Abstract
BACKGROUND Radical prostatectomy (RP) is recommended in case of localized or locally advanced prostate cancer (PCa), but it can lead to side effects, including urinary incontinence (UI) and erectile dysfunction (ED). Magnetic resonance imaging (MRI) is recommended for PCa diagnosis and staging, but it can also improve preoperative risk-stratification. PURPOSE This nonsystematic review aims to provide an overview on factors involved in RP side effects, highlighting anatomical and pathological aspects that could be included in a structured report. EVIDENCE SYNTHESIS Considering UI evaluation, MR can investigate membranous urethra length (MUL), prostate volume, the urethral sphincter complex, and the presence of prostate median lobe. Longer MUL measurement based on MRI is linked to a higher likelihood of achieving continence restoration. For ED assessment, MRI and diffusion tensor imaging identify the neurovascular bundle and they can aid in surgery planning. Finally, MRI can precisely describe extra-prostatic extension, prostate apex characteristics and lymph-node involvement, providing valuable preoperative information for PCa treatment. CONCLUSIONS Anatomical principals structures involved in RP side effects can be assessed with MR. A standardized MR report detailing these structures could assist urologists in planning optimal and tailored surgical techniques, reducing complications, and improving patients' care.

A novel quantitative model based on gross tumor volume corresponding to anatomical distribution measured with multidetector computed tomography to determine the resectability of non‑distant metastatic esophageal squamous cell carcinoma. Oncol Lett 2023; 26:485. [PMID: 37818136 PMCID: PMC10561156 DOI: 10.3892/ol.2023.14072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 09/12/2023] [Indexed: 10/12/2023] Open
Abstract
It is important to accurately determine the resectability of thoracic esophageal squamous cell carcinoma (ESCC) for treatment decision-making. Previous studies have revealed that the CT-derived gross tumor volume (GTV) is associated with the staging of ESCC. The present study aimed to explore whether the anatomical distribution-based GTV of non-distant metastatic thoracic ESCC measured using multidetector computed tomography (MDCT) could quantitatively determine the resectability. For this purpose, 473 consecutive patients with biopsy-confirmed non-distant metastatic thoracic ESCC who underwent contrast-enhanced CT were randomly divided into a training cohort (TC; 376 patients) and validation cohort (VC; 97 patients). GTV was retrospectively measured using MDCT. Univariate and multivariate analyses were performed to identify the determinants of the resectability of ESCC in the TC. Receiver operating characteristic (ROC) analysis was performed to clarify whether anatomical distribution-based GTV could help quantitatively determinate resectability. Unweighted Cohen's Kappa tests in VC were used to assess the performance of the previous models. Univariate analysis demonstrated that sex, anatomic distribution, cT stage, cN stage and GTV were related to the resectability of ESCC in the TC (all P<0.05). Multivariate analysis revealed that GTV [P<0.001; odds ratio (OR) 1.158] and anatomic distribution (P=0.027; OR, 1.924) were independent determinants of resectability. ROC analysis revealed that the GTV cut-offs for the determination of the resectability of the upper, middle and lower thoracic portions were 23.57, 22.89 and 22.58 cm3, respectively, with areas under the ROC curves of >0.9. Unweighted Cohen's Kappa tests revealed an excellent performance of the ROC models in the upper, middle and lower thoracic portions with Cohen k-values of 0.913, 0.879 and 0.871, respectively. On the whole, the present study demonstrated that GTV and the anatomic distribution of non-distant metastatic thoracic ESCC may be independent determinants of resectability, and anatomical distribution-based GTV can effectively be used to quantitatively determine resectability.

Standardization of Body Composition Status in Patients with Advanced Urothelial Tumors: The Role of a CT-Based AI-Powered Software for the Assessment of Sarcopenia and Patient Outcome Correlation. Cancers (Basel) 2023; 15:cancers15112968.

Abstract
BACKGROUND Sarcopenia is a well know prognostic factor in oncology, influencing patients' quality of life and survival. We aimed to investigate the role of sarcopenia, assessed by a Computed Tomography (CT)-based artificial intelligence (AI)-powered-software, as a predictor of objective clinical benefit in advanced urothelial tumors and its correlations with oncological outcomes. METHODS We retrospectively searched patients with advanced urothelial tumors, treated with systemic platinum-based chemotherapy and an available total body CT, performed before and after therapy. An AI-powered software was applied to CT to obtain the Skeletal Muscle Index (SMI-L3), derived from the area of the psoas, long spine, and abdominal muscles, at the level of L3 on CT axial images. Logistic and Cox-regression modeling was implemented to explore the association of sarcopenic status and anthropometric features to the clinical benefit rate and survival endpoints. RESULTS 97 patients were included, 66 with bladder cancer and 31 with upper-tract urothelial carcinoma. Clinical benefit outcomes showed a linear positive association with all the observed body composition variables variations. The chances of not experiencing disease progression were positively associated with ∆_SMI-L3, ∆_psoas, and ∆_long spine muscle when they ranged from ~10-20% up to ~45-55%. Greater survival chances were matched by patients achieving a wider ∆_SMI-L3, ∆_abdominal and ∆_long spine muscle. CONCLUSIONS A CT-based AI-powered software body composition and sarcopenia analysis provide prognostic assessments for objective clinical benefits and oncological outcomes.

Aorta and tracheobronchial invasion in esophageal cancer: comparing diagnostic performance of 3.0-T MRI and CT. Eur Radiol 2023:10.1007/s00330-023-09425-2. [PMID: 36692595 DOI: 10.1007/s00330-023-09425-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 12/11/2022] [Accepted: 01/02/2023] [Indexed: 01/25/2023]
Abstract
OBJECTIVES To compare between the diagnostic performance of 3.0-T MRI and CT for aorta and tracheobronchial invasion in patients with esophageal cancer (EC). METHODS We prospectively included patients with pathologically confirmed EC from November 2018 to June 2021, who had baseline stage of T3-4N0-2M0 and restaging after neoadjuvant chemotherapy. All patients underwent contrast-enhanced CT and MRI of the thorax. Two independent blinded radiologists scored image quality and the presence of invasion. Agreements between the two readers were calculated using kappa test. The sensitivity, specificity, accuracy, positive predict value (PPV), and negative predict value (NPV) of MRI and CT in evaluating invasion were calculated. The net reclassification index (NRI) was used to evaluate the change in the number of patients correctly classified by MRI and CT. RESULTS A total of 70 patients (64.8 ± 9.0 years; 53 men) were enrolled. Inter-reader agreements of image quality scores and presence of invasion by MRI and CT between the two readers were almost perfect (kappa > 0.80). The accuracy of MRI in evaluating thoracic aorta invasion was significantly higher than that of CT (reader 1: 90.0% vs. 71.4%; reader 2: 92.9% vs. 70.0%, respectively), and the accuracy of MRI in evaluating tracheobronchial invasion also was significantly higher than that of CT (reader 1: 92.9% vs. 72.9%; reader 2: 95.7% vs. 70.0%, respectively). NRI values were positive in both the evaluation of aorta and tracheobronchial invasion. CONCLUSIONS The accuracy of 3-T MRI in determining thoracic aorta and tracheobronchial invasion is significantly higher than that of CT. KEY POINTS • 3.0-T MRI was significantly more accurate than CT in assessing invasion of the thoracic aorta in patients with esophageal cancer. • 3.0-T MRI was also significantly more accurate than CT in assessing tracheobronchial invasion in patients with esophageal cancer. • 3.0-T MRI has a higher diagnostic performance than CT in evaluating patients with suspected aortic or tracheobronchial invasion in esophageal cancer.

Abstract
OBJECTIVE This article aims to show the usefulness of the pneumo-computed tomography gastric distention technique in the detection and morphological characterization of subepithelial gastric lesions. We correlate the pneumo-computed tomography and pathology findings in lesions studied at our institution and review the relevant literature. CONCLUSION Pneumo-computed tomography, combined with multiplanar reconstructions, three-dimensional reconstructions, and virtual endoscopy, is useful for delineating the morphological details of subepithelial gastric lesions, thanks to the additional gastric distention. This technique better delimits and characterizes the upper and lower margins of the lesions. Pneumo-computed tomography can be considered a useful noninvasive imaging techniques for characterizing these lesions.

Abstract
BACKGROUND CT is the most commonly used method to stage esophageal cancer (EC). However, the reported CT T-staging criteria for EC are controversial. PURPOSE To determine and validate the optimal esophageal wall thickness (EWT) threshold on CT to distinguish lesions with different T stages in esophageal squamous cell carcinoma (ESCC) patients. METHODS One thousand, one hundred-two consecutive patients with histopathologically confirmed ESCC between July 2014 and April 2020 were retrospectively reviewed. All patients underwent a preoperative CT examination and surgical treatment. The maximal EWT of the lesions on CT was measured. Patients were divided into pT1, pT2, pT3 and pT4 subgroups according to the pathologic stage. We employed the support vector machine, where linear kernels were leveraged to determine the optimal threshold to classify samples with different T stages. 90% of samples from each subgroup were randomly selected as the training set, while the remainder comprised the testing set. RESULTS The mean EWTs of the pT1, pT2, pT3 and pT4 subgroups were 4.9 ± 2.6 mm, 8.1 ± 2.3 mm, 12.4 ± 3.6 mm, and 18.6 ± 4.4 mm, respectively. Differences in the EWT between the four subgroups or between adjacent subgroups were significant (p < 0.001), and esophageal wall became thicker with increasing pT stage. We utilized MATLAB 2020a to implement the SVM model and ran the code 10 times. The accuracy of the model was 60.29 ± 2.33%. The thresholds between samples from pT1/pT2, pT2/pT3 and pT3/pT4 lesions were 5.5 ± 0.3 mm, 10.8 ± 0.8 mm and 15.9 ± 0.5 mm, respectively. CONCLUSIONS Possibility of predicting T stage of ESCC by EWT on CT scans was limited to 60% by model examination with large sample size.

Abstract
Gastroesophageal reflux disease (GERD) is a common condition and impairs the quality of life for millions of patients, accounts for considerable health care spending, and is a primary risk factor for esophageal adenocarcinoma. There have been substantial advances in understanding the pathogenesis of GERD and its complications and much progress in diagnosis and management of GERD; however, these have not been comprehensively discussed in the recent radiology literature. Understanding the role of imaging in GERD and its complications is important to aid in multidisciplinary treatment of GERD. GERD results from prolonged or recurrent reflux of gastric contents into the esophagus. Common symptoms include heartburn or regurgitation. Prolonged reflux of gastric contents into the esophagus can cause erosive esophagitis. Over time, the inflammatory response related to esophagitis can lead to deposition of fibrous tissue and development of strictures. Alternatively, the esophageal mucosa can undergo metaplasia (Barrett esophagus), a precursor to dysplasia (which can lead to adenocarcinoma). Conventional barium esophagography has long been considered the primary imaging modality for the esophagus, and the fluoroscopic findings for diagnosis of GERD have been well established. Multimodality imaging has a clear role in detection and assessment of the complications of GERD, specifically reflux esophagitis and Barrett esophagus; differentiation of benign and malignant strictures; and detection, staging, and posttreatment surveillance of esophageal adenocarcinoma. Given the dramatic changes in utilization of abdominal imaging during the past 2 decades, with significantly declining volume of fluoroscopic procedures and concomitant increase in CT and MRI studies, it is crucial that modern radiologists appreciate the value of barium esophagography in the workup of GERD and recognize the key imaging features of GERD and its complications at CT and MRI.

Abstract
Esophageal cancer is a major cause of morbidity and mortality worldwide. Recent advancements in the management of esophageal cancer have allowed for earlier detection, improved ability to monitor progression, and superior treatment options. These innovations allow treatment teams to formulate more customized management plans and have led to an increase in patient survival rates. For example, in order for the most effective management plan to be constructed, accurate staging must be performed to determine tumor resectability. This article reviews the multimodality imaging approach involved in making a diagnosis, staging, evaluating treatment response and detecting recurrence in esophageal cancer.

The aim of this study was to assess the potential of a prone chest CT for the evaluation of esophageal cancer, as compared with a routine supine chest CT. 69 patients (67±18 years old) with pathologically confirmed esophageal cancers underwent MDCT in the supine and prone positions. The supine CT was performed first, followed by the prone position. Localization and staging of individual esophageal lesions on both the prone and supine CTs were assessed by two thoracic radiologists, using a scoring system that consisted of three confidence scales, and the results were correlated with the endoscopic and surgical findings. The mean confidence score for the detection of esophageal cancer was higher in the prone position (2.58±0.74) than that in the supine position (2.42±0.83) with statistical significance (p=0.002). The mean confidence score for predicting local invasion in the selected patients (n=18) who underwent esophagectomy was also higher in the prone position (2.39±0.85) than that in the supine position (2.06±0.73) with statistical significance (p=0.01). In 10 of 11 cases that showed definitive determination for periesophageal infiltration or adjacent organ invasion on the prone CT (score 3), the corresponding findings were also observed in the post-operative evaluations. In conclusion, prone chest CT for evaluating esophageal cancer could have advantages in regards to the localization of esophageal cancer and predicting local invasion compared to that of routine supine CT and can improve the diagnostic accuracy of chest CTs.

Abstract
In this report, we present a case in which good results were achieved by treatment using a free jejunal patch graft with virtual endoscopy (VE) assistance in a patient whose swallowing had failed to improve for 40 years after he mistakenly swallowed sulfuric acid, despite pectoralis major myocutaneous flap grafting and frequent balloon dilatation surgery. During the last 20 years, virtual computed tomography imaging has improved remarkably and continues to be used to address new challenges. For reconstructive surgeons, the greatest advantage of VE is that it is a noninvasive modality capable of visualizing areas inaccessible to a flexible endoscope. Using VE findings, we were able to visualize the 3-dimensional shape beyond the stenosis. VE can also help predict the area of the defect after contracture release.

Abstract
OBJECTIVES To compare the T staging of resectable oesophageal cancer (OC) using radial VIBE (r-VIBE) and endoscopic ultrasound (EUS) with pathological confirmation of the T stage. METHODS Forty-three patients with endoscopically proven OC and indeterminate T1/T2/T3/T4a stage by computed tomography (CT) and EUS were imaged on a 3-T magnetic resonance imaging (MRI) scanner. T stage was scored on MRI and EUS by two independent radiologists and one endoscopist, respectively, and compared with postoperative pathological findings. T staging agreement between r-VIBE and EUS with postoperative pathological T staging was analysed by a kappa test. RESULTS EUS and pathological T staging showed agreement of 69.8% (30/43). Radial VIBE and pathological T staging agreement was 86.0% (37/43) and 90.7% (39/43) for readers 1 and 2, respectively. High accuracy for T1/T2 stage was obtained for both r-VIBE readers (90.5% and 100% for reader 1 and reader 2, respectively) and EUS reader (100%). For T3/T4, r-VIBE showed accuracy of 81.8% and 90.9% for reader 1 and reader 2, respectively, while for EUS, accuracy was only 68.2% compared with pathological T staging. CONCLUSIONS Contrast-enhanced r-VIBE is comparable to EUS in T staging of resectable OC with stage of T1/T2, and is superior to EUS in staging of T3/T4 lesions. KEY POINTS • Radial VIBE may be useful in preoperative T staging of OC • Accuracy of staging on r-VIBE is higher in T1/2 than in T3/4 • Accuracy of EUS was 100% and 68.2% for T1/T2 and T3/T4 stage • Inter-reader agreement of T staging for r-VIBE was good.

Abstract
PURPOSE The goal of this study was to analyze the effect of oral sherbet application on esophageal distension and esophageal evaluation with thoracic multidetector-row computed tomography (MDCT) regarding sherbet timing. MATERIALS AND METHODS A total 120 patients (65 men, 55 women) with a mean age of 59.7 years who were given 4g sherbet powder to be swallowed 60, 30 or 10seconds before thoracic MDCT were included. Inner esophageal diameter was measured in three planes at three anatomic levels. Area of esophageal lumen and assessable length of the esophagus were calculated and statistically analyzed using repeated-measures-ANOVA and post-hoc-t-tests. Results were compared groupwise and intra-individually with previous examinations without sherbet. RESULTS Intra-individual comparison and subgroup-analysis showed that esophageal distension was significantly better when sherbet was used (mean inner area: 1.98±0.66cm(2) vs. 0.49±0.14cm(2)) (P<0.001). After preparation, in average 80.2% of the esophageal length were assessable compared to 39.2% without sherbet (P<0.001). Timing of sherbet administration within one minute before scan-start revealed no significant differences (P=0.9), yet a shorter delay to scan-start led to the best results. CONCLUSION Oral sherbet administration within one minute before scan-start improves esophageal distension and evaluation using thoracic MDCT. This method of esophageal preparation is simple, can easily be applied in clinical routine and may improve the diagnosis of esophageal pathologies.

Abstract
PURPOSE To determine the feasibility of diffusion-tensor magnetic resonance (MR) imaging and tractography as a means of evaluating the depth of mural invasion by esophageal carcinomas. MATERIALS AND METHODS This study was approved by the institutional review board, and written informed consent was obtained from each patient. Twenty esophageal specimens, each containing a carcinoma, were studied with a 7.0-T MR imaging system equipped with a four-channel phased-array surface coil. Diffusion-tensor MR images were obtained with a field of view of 50-60 mm × 25-30 mm, matrix of 256 × 128, section thickness of 1 mm, b value of 1000 sec/mm(2), and motion-probing gradient in seven noncollinear directions. The MR images were compared with the histopathologic findings as the reference standard. The differences in diffusion-tensor MR imaging parameters between the carcinoma and the layers of the esophageal wall were statistically analyzed by using the Dunnett test. RESULTS In all 20 carcinomas (100%), the diffusion-weighted images, apparent diffusion coefficient (ADC) maps, fractional anisotropy (FA) maps, λ1 maps, and direction-encoded color FA maps made it possible to determine the depth of tumor invasion of the esophageal wall that was observed during histopathologic examination. The λ1 maps showed the best contrast between the carcinomas and the layers of the esophageal wall. The carcinomas had both lower ADC values and lower FA values than the normal esophageal wall; thus, the carcinomas were clearly demarcated from the normal esophageal wall. Diffusion-tensor tractography images were also useful for determining the depth of tumor invasion of the esophageal wall. CONCLUSION Diffusion-tensor MR imaging and tractography are feasible in esophageal specimens and provide excellent morphologic data for the evaluation of mural invasion by esophageal carcinomas.

Abstract
A variety of benign conditions can affect the oesophagus, both primarily and secondarily. Traditionally fluoroscopic oesophagography and endoscopy have formed the mainstay for investigating oesophageal diseases. Increasing use of cross-sectional imaging means that many such diseases and their thoracic complications are now detected at computed tomography (CT), which is very often the first imaging tool. This review describes the CT manifestations of a range of benign oesophageal conditions and discusses the role of CT in their evaluation.

Abstract
BACKGROUND The purpose of this study was to determine whether the degree of esophageal circumferential tumor involvement and tumor size of resectable esophageal squamous cell carcinoma (ESCC) assessed on computed tomography could predict T category. METHODS One hundred eighty-five consecutive patients with ESCC underwent radical esophagectomy less than 3 weeks after contrast-enhanced computed tomography. The degree of esophageal circumferential tumor involvement and tumor size of ESCC expressed as tumor length, maximal thickness, and gross tumor volume were evaluated on computed tomography. Statistical analyses were performed to identify whether degree of esophageal circumferential tumor involvement and tumor size could predict T category. RESULTS Esophageal squamous cell carcinoma with whole esophageal circumferential tumor involvement was more likely to be at T3 category, whereas tumor without this involvement was more likely to be at T1 or T2 category (p < 0.001). Degree of esophageal circumferential tumor involvement could distinguish ESCC at T1/T2 from ESCC at T3 category with a sensitivity of 77.4% and specificity of 74.8%. Tumor length, maximal thickness, and gross tumor volume increased with advancing T category (p < 0.001). Mann-Whitney tests showed that tumor size could distinguish T category (p < 0.001). Compared with degree of esophageal circumferential tumor involvement, tumor length, and maximal thickness, gross tumor volume could be a better differentiating indicator between T1 and T2 categories (cutoff, 5.15 cm(3)), between T1 and T3 categories (cutoff, 11.1 cm(3)), between T2 and T3 categories (cutoff, 17.75 cm(3)), and between T1/T2 and T3 categories (cutoff, 15.9 cm(3)), with sensitivity of 81.3%, 88.8%, 68.8%, and 78.8%, and specificity of 76%, 88%, 67.5%, and 75.4%, respectively. CONCLUSIONS Gross tumor volume of resectable ESCC measured with computed tomography could be a recommended indicator for predicting T category.

Abstract
This study was conducted to investigate the clinical application of three-dimensional (3D) reconstructed computed tomography (CT) images in detecting and gaining information on esophageal foreign bodies (FBs). Two patients with esophageal FBs were enrolled for analysis. In both cases, 3D reconstructed images were compared with the FB that was removed according to the object shape, size, location, and orientation in the esophagus. The results indicate the usefulness of conversion of CT data to 3D images to help in diagnosis and treatment. Use of 3D images prior to treatment allows for rapid prototyping and surgery simulation.

Abstract
AIMS This study aims to compare transverse images and vessel probe (VP) in MPR mode reconstructions obtained by 16-row MDCT with the histological findings in the preoperative T staging of esophageal cancer. MATERIALS AND METHODS Thirty-one patients (23 M, 8 F, mean age 63.2) with endoscopic and histological diagnosis of esophageal carcinoma underwent CT examination. Esophageal lumen was distended by CO2 and a biphasic technique with 35 s and 70 s delay was used after intravenous injection of contrast material. Transverse and VP in MPR mode images were evaluated and the following parameters were considered: presence and location of the tumor; esophageal wall thickness and enhancement; depth of visceral wall invasion; periesophageal fat morphology and infiltration of adjacent organs. Preoperative staging was performed and then it was compared with the histological findings considered as reference standard. RESULTS Sensibility, negative predictive and accuracy values were 67%, 64% and 79% by using axial images for preoperative T staging, while the use of VP increased the previous values up to 83%, 78% and 89%, respectively. CONCLUSIONS In the preoperative staging of esophageal cancer, VP in MPR mode reconstructions obtained by 16-row MDCT increase the sensibility and diagnostic accuracy values in the T parameter evaluation compared with axial images.

Abstract
BACKGROUND Pre-surgical characterization and staging of esophageal cancer with only one imaging method could be useful since gastric invasion determines the scope of resection and the kind of surgery to be performed. Our aim is to demonstrate the usefulness of Pneumo-64-MDCT (PnCT64) in the presurgical characterization of esophageal neoplasms in correlation with surgical findings. MATERIALS AND METHODS A total of 50 patients with diagnosis of esophageal neoplasm were prospectively studied. A 14 French Foley catheter was used transorally in all patients. Air was instilled through the catheter to achieve esophageal distension. A 64-row MDCT scan was performed and the tumor was characterized according to scope, shape and anatomic location by using multiplanar 3D reconstructions and virtual endoscopy. Wall infiltration and presence of adenopathies were analyzed. RESULTS Adequate gastroesophageal distension was achieved in all patients. In 44/50 patients, wall thickening was observed, and in 34/50 regional adenopathies were found. In 29/50 patients the lesion was found in the lower third and in the gastroesophageal junction. The surgical correlation for wall infiltration was 85.7%. CONCLUSIONS PnCT64 proved to be useful and safe for identification of esophageal wall thickening and presurgical characterization. Optimal distension allowed definition of both upper and lower borders of the tumors located in the gastroesophageal junction, of utmost importance to determine the surgical approach.

Abstract
Multi-detector computed tomography (CT) offers new opportunities in the imaging of the gastrointestinal tract. Its ability to cover a large volume in a very short scan time, and in a single breath hold with thin collimation and isotropic voxels, allows the imaging of the entire esophagus with high-quality multiplanar reformation and 3D reconstruction. Proper distention of the esophagus and stomach (by oral administration of effervescent granules and water) and optimally timed administration of intravenous contrast material are required to detect and characterize disease. In contrast to endoscopy and double-contrast studies of the upper GI tract, CT provides information about both the esophageal wall and the extramural extent of disease. Preoperative staging of esophageal carcinoma appears to be the main indication for MDCT. In addition, MDCT allows detection of other esophageal malignancies, such as lymphoma and benign esophageal tumors, such as leiomyma. A diagnosis of rupture or fistula of the esophagus can be firmly established using MDCT. Furthermore, miscellaneous esophageal conditions, such as achalasia, esophagitis, diverticula, and varices, are incidental findings and can also be visualized with hydro-multi-detector CT. Multi-detector CT is a valuable tool for the evaluation of esophageal wall disease and serves as an adjunct to endoscopy.

Abstract
Accurate staging of disease is necessary in patients with newly diagnosed esophageal cancer in order to prompt appropriate curative or palliative therapy. Computed tomography (CT) may be used to evaluate for local spread into adjacent structures (T4 disease) and to diagnose distant metastases (M1). Endoscopic ultrasonography (EUS) is the modality of choice for distinguishing T1 tumors from higher stage lesions and for detecting and sampling regional lymph nodes (N1 disease). Positron emission tomography (PET) scanning is most helpful for detecting previously occult distant metastases. Optimal staging generally requires a multimodality approach.

Abstract
OBJECTIVE The objective of our study was to evaluate the performance of MDCT in the preoperative T-staging of gallbladder cancer and to determine whether adding multiplanar reconstruction (MPR) images to axial images can improve the accuracy of MDCT for the T-staging of gallbladder cancer. MATERIALS AND METHODS Two abdominal radiologists retrospectively reviewed by consensus axial images of portal phase MDCT scans of 118 patients who had pathologically confirmed gallbladder cancers; they then reviewed the axial and MPR images from 53 of the 118 patients who had undergone MPR imaging. Local disease spread was evaluated according to the TNM system, and the results were compared with the pathologic findings using the McNemar test. The MDCT performance to differentiate each T-stage was evaluated using Fisher's exact test. RESULTS The sensitivities of the ability to differentiate the < or = T1 versus > or = T2 lesions, < or = T2 versus > or = T3 lesions, and < or = T3 versus T4 lesions were 79.3%, 92.7%, and 100%, respectively; the specificities were 98.8%, 86%, and 100%, respectively (p < 0.0001). The overall accuracy for the T-stage was 83.9%. In the 53 patients with MPR images, the combined reading of the axial and MPR images increased the diagnostic accuracy compared with axial image reading only from 71.7% to 84.9%, a statistically significant degree (p = 0.0233). CONCLUSION MDCT provided 83.9% accuracy in the diagnosis of the local extent of gallbladder carcinomas, thereby showing acceptable sensitivity and specificity. The addition of MPR images to the axial CT data increased the accuracy.

Abstract
OBJECTIVE The self-expanding metallic stent (SEMS) is widely used in the palliative treatment of stenosing esophageal cancer. Multidetector computed tomography (MDCT) allows volumetric investigation including virtual endoscopy. The aim of this study was to determine the feasibility of MDCT follow-up of esophageal SEMS and to describe the imaging patterns encountered as well as correlating them with fibroscopic evaluation. MATERIAL AND METHODS Thirteen consecutive patients (10 M, mean age 64 years) with esophageal SEMS as a palliative treatment underwent MDCT for recurrent dysphagia (n =7), chest pain and fever (n = 1) or follow-up without symptoms (n = 5). Patency and esophageal wall patterns were studied and compared with diagnosis by fibroscopy. RESULTS No metallic artefact related to the SEMS was observed. At the SEMS level, MDCT revealed a tissular lump (n = 1), a thin recurrent layer of tissue (n = 1), extrinsic compression (n = 1), fluid stasis (n =7) and intussusception of the gastric wall into the SEMS (n =4). The esophageal wall was analyzed by MDCT (peripheral thickening around the stent (n = 8), tumor overgrowth under or above the SEMS level (n = 8)) and showed tracheal compression (n = 3). At the level of the SEMS, fibroscopy showed tumor recurrence (n = 2), a thin recurrent layer of tissue (n = 1), a distorted SEMS (n = 1) and a tumor overgrowth under or above the SEMS level (n = 6). In comparison with fibroscopy, MDCT satisfactorily diagnosed the SEMS patency in 92% of cases and the esophageal wall in 73%. CONCLUSIONS Morphology, patency of the SEMS and analysis of the esophageal wall can be performed by MDCT with a good degree of accuracy as compared to fibroscopy. In such patients in palliative care, a non-invasive investigation is worth promoting as a first-line procedure.

Abstract
Intramural hematoma of the esophagus (IHE) is a rare but well-documented condition that is part of the spectrum of esophageal injuries which includes the more common Mallory-Weiss tear and Boerhaave's syndrome. Acute retrosternal or epigastric pain is a common clinical feature, which can be accompanied by dysphagia, odynophagia, or hematemesis. An early differentiation from Mallory-Weiss tear, Boerhaave syndrome, ruptured aortic aneurysm, aortic dissection, acute myocardial infarction, or pulmonary pathology can be difficult. Computed tomography (CT) is the imaging modality of choice and characteristically reveals a concentric or eccentric thickening of the esophageal wall with well-defined borders and variable degree of obliteration of the lumen. Measurement of the attenuation values within the lesion will reveal blood density which varies according to the age of the hematoma. CT should be considered the preferred diagnostic technique, thereby facilitating proper clinical management. Early diagnosis is crucial as most patients may be treated conservatively with good outcome.

Abstract
Squamous cell carcinomas and adenocarcinomas account for the majority of cases of esophageal cancer. Esophageal cancer often is diagnosed in advanced stages as clinical symptoms are lacking in early stages. The major aims of imaging in esophageal cancer are to determine local tumor extension (T and N staging), to rule out systemic disease (M staging), and to assess response to neoadjuvant therapy (response evaluation). CT is still inferior to endoscopic ultrasound in differentiating T stages and detecting regional lymph node metastases. However, it plays a central role in determining infiltration into adjacent organs (T4 stage) and in ruling out distant metastases. Multislice-CT (MSCT) offers the possibility of reconstructions, which often help to assess the relationship between tumor and anatomic landmarks like the tracheobronchial tree or the diaphragm. First results of CT volumetry for response evaluation are promising; however, PET and PET/CT with the glucose analogue FDG are the standard methods to evaluate response to neoadjuvant therapy.

Abstract
Accurate staging of cancer is of fundamental importance to treatment selection and planning. Current staging paradigms focus, first, on a detailed delineation of the primary tumour in order to determine its suitability for resection, and, thereafter, on assessment of the presence of metastatic spread that would alter the surgical approach, or mandate non-surgical therapies. This approach has, at its core, the assumption that the best, and sometimes the only, way to cure a patient of cancer is by surgical resection. Unfortunately, all non-invasive techniques in current use have imperfect ability to identify those primary tumours that are able to be completely excised, and even worse ability to define the extent of metastatic spread. Nevertheless, because of relatively low cost and widespread availability, computed tomography (CT) scanning is the preferred methodology for tumour, nodal and systemic metastasis (TNM) staging. This is often supplemented by other tests that have improved performance in particular staging domains. For example, magnetic resonance imaging (MRI), mammography, or endoscopic ultrasound may be used as complementary tests for T-staging; surgical nodal sampling for N-staging; and bone scanning, MRI or ultrasound for M-staging. Accordingly, many patients undergo a battery of investigations but, even then, are found to have been incorrectly staged based on subsequent outcomes. Even for those staged surgically, pathology can only identify metastases within the resection specimens and has no capability for detecting remote disease. As a result of this, many patients undergo futile operations for disease that could never have been cured by surgery. In the case of restaging, the situation is even worse. The sequelae of prior treatment can be difficult to differentiate from residual cancer and the likelihood of successful salvage therapy is even less than at presentation. More deleteriously, patients may be subjected to additional morbid treatments when cure has already been achieved. Thus, in post-treatment follow-up, the presence and extent of disease is equally critical to treatment selection and patient outcome as it is in primary staging. One of the major strengths of positron emission tomography (PET)/CT as a cancer staging modality is its ability to identify systemic metastases. At any phase of cancer evaluation, demonstration of systemic metastasis has profound therapeutic and prognostic implications. Only in the absence of systemic metastasis does nodal status become important, and only when unresectable nodal metastasis has been excluded does T-stage become important. There are now accumulating data that PET/CT could be used as the first, rather than the last test to assess M- and N-stage for evaluating cancers with an intermediate to high pre-test likelihood of metastatic disease based on poor long-term survival. In this scenario, there is great opportunity for subsequently selecting and tailoring the performance of anatomically based imaging modalities to define the structural relations of abnormalities identified by PET, when this information would be of relevance to management planning. Primary staging of oesophageal cancer and restaging of colorectal cancer are illustrative examples of a new paradigm for cancer imaging.

Abstract
This paper describes the spectrum of imaging features of oesophageal adenocarcinoma seen using high-resolution T2-weighted (T2W) magnetic resonance imaging (MRI). Thirty-nine patients with biopsy-proven oesophageal adenocarcinoma were scanned using an external surface coil. A sagittal T2W sequence was used to localise the tumour and to plan axial images perpendicular to the tumour. Fast spin-echo (FSE) T2W axial sequence parameters were: TR/TE, 3,300-5,000 ms/120-80 ms; field of view (FOV) 225 mm, matrix 176x512(reconstructed) mm to 256x224 mm, giving an in-plane resolution of between 1.28x0.44 mm and 0.88x1.00 mm, with 3-mm slice thickness. Thirty-three patients underwent resection and the MR images were compared with the histological whole-mount sections. There were four T1, 12 T2, and 17 T3 tumours. The T2W high-resolution MRI sequences produced detailed images of the oesophageal wall and surrounding structures. Analysis of the imaging appearances for different tumour T stages enabled the development of imaging criteria for local staging of oesophageal cancer using high-resolution MRI. Our study illustrates the spectrum of appearances of oesophageal cancer on T2W high-resolution MRI, and using the criteria established in this study, demonstrates the potential of this technique as an alternative non-invasive method for local staging for oesophageal cancer.

Abstract
In the past few years, major improvements and new technologies have been proposed and applied in esophageal surgery. Its evolution depended not only on a thorough knowledge of surgical anatomy and technique, but also on important developments in pre- and postoperative care. Esophageal resection for cancer is still associated with high morbidity and mortality. Postoperative complications may be either patient or surgeon related. Patient-related factors include age, malnutrition, immunodepression and associated diseases. The surgeon-related factors are surgical experience, hospital volume and multidisciplinary approach. Preoperative evaluation is defined as the process of clinical assessment that precedes the delivery of anesthesia. The principle is to gain information concerning patients that leads to modification of their management, and improves the outcome from surgery.

Abstract
The aim of this study was to determine whether multidetector computed tomography (MDCT) imaging, including CT esophagography (CTE), can be used as a comprehensive imaging test for esophageal tumors. Twenty-three patients with esophageal neoplasms underwent MDCT with esophageal distension and endoscopy. Of them, 20 underwent barium study. Two radiologists independently reviewed MDCT images with 3D CT esophagography (CTE) including CT endoscopy and were asked to determine the presence of the esophageal lesions and characterize them using a five-point confidence scale. The radiologists' performance for the lesion detection and characterization was evaluated by receiver operating characteristic (ROC) analysis. They were also requested to determine the local staging of esophageal cancer, and the overall accuracies of MDCT for local staging were calculated. The ability of MDCT with CTE was also evaluated compared with conventional studies. CTE images successfully revealed 14 of 16 esophageal cancers and all seven submucosal tumors. Two esophageal cancers, both confined to the mucosal layer, were undetected. The Az values of the MDCT images were 0.954-0.957 for determining the presence of a lesion and 0.954-0.995 for differentiating between cancer and submucosal tumors. The overall accuracies for T and N staging were 42.9% and 85.7%, respectively. In 80% and 74% of cases, CTE gave similar or superior information to barium study and endoscopy, respectively. MDCT esophagography has the potential to serve as a comprehensive imaging modality for evaluating esophageal tumors as it provides accurate information regarding the detection and characterization of esophageal tumors as well as the similar information to conventional studies.
