Abstract
Background SMARCA4-deficient undifferentiated tumor (SMARCA4-UT) is a class of high-grade malignant tumors that has only been described in recent years, with an undifferentiated or rhabdoid morphology and genetic deletion of SMARCA4 (BRG1), a subunit of the BRG1-associated factors (BAFs) chromatin remodeling complex. It is a rare tumor type that occurs in young to middle-aged men and usually presents as a compressive thoracic mass with rapid progression and poor prognosis. However, much remains unknown about the clinical and imaging manifestations of the disease. Case Description Herein, we report a 51-year-old man who came to our hospital with multiple enlarged lymph nodes in the chest after a computed tomography (CT) examination at another hospital. The patient underwent conventional ultrasound (US), contrast-enhanced ultrasound (CEUS), magnetic resonance imaging (MRI), 18F-fluorodeoxyglucose positron emission tomography/CT (PET/CT), and finally confirmed the diagnosis of SMARCA4-UT by US-guided puncture biopsy. After symptomatic management, the patient was transferred to another hospital and we performed a short-term follow-up. Conclusions During this procedure, we obtained a series of relevant clinical and imaging data, especially US and CEUS images, which were described for the first time, offering valuable imaging information that will contribute to the clinical diagnosis of this disease to a certain extent. Moreover, this case highlights the efficacy of CEUS in identifying internal necrosis within tumors and lymph nodes, thereby improving the success rate of obtaining tumor tissue for pathological diagnosis. These findings substantiate the practical utility of US and CEUS in the context of mediastinal SMARCA4-UT, emphasizing their potential for widespread clinical adoption.

Abstract
Thoracic ultrasound (TU) has rapidly gained popularity over the past 10 years. This is in part because ultrasound equipment is available in many settings, more training programmes are educating trainees in this technique, and ultrasound can be done rapidly without exposure to radiation. The aim of this review is to present the most interesting and innovative aspects of the use of TU in the study of thoracic diseases. In pleural diseases, TU has been a real revolution. It helps to differentiate between different types of pleural effusions, guides the performance of pleural biopsies when necessary and is more cost-effective under these conditions, and assists in the decision to remove thoracic drainage after talc pleurodesis. With the advent of COVID19, the use of TU has increased for the study of lung involvement. Nowadays it helps in the diagnosis of pneumonias, tumours and interstitial diseases, and its use is becoming more and more widespread in the Pneumology ward. In recent years, TU guided biopsies have been shown to be highly cost-effective, with other advantages such as the absence of radiation and the possibility of being performed at bedside. The use of contrast in ultrasound to increase the cost-effectiveness of these biopsies is very promising. In the study of the mediastinum and peripheral pulmonary nodules, the introduction of echobronchoscopy has brought about a radical change. It is a fully established technique in the study of lung cancer patients. The introduction of elastography may help to further improve its cost-effectiveness. In critically-ill patients, diaphragmatic ultrasound helps in the assessment of withdrawal of mechanical ventilation, and is now an indispensable tool in the management of these patients. In neuromuscular patients, ultrasound is a good predictor of impaired lung function. Currently, in Neuromuscular Disease Units, TU is an indispensable tool. Ultrasound study of the intercostal musculature is also effective in the study of respiratory function, and is widely used in Respiratory Rehabilitation. In Intermediate Care Units, thoracic ultrasound is indispensable for patient management. In these units there are ultrasound protocols for the management of patients with acute dyspnoea that have proven to be very effective.

Abstract
Cancer cases have been on the rise over the world. Cancer treatment can benefit from an early accurate diagnosis. Percutaneous needle biopsy under the guidance of CT images is the most common method to obtain tumor samples for accurate diagnosis. However, due to the lack of vascular information in the CT images, the biopsy procedure is at great risk, especially for the tumor surrounded by vessels. In this study, a biomechanical model and surface elastic registration-based fusion algorithm were developed to map the vessels from contrast-enhanced CT images of the liver and lung to the corresponded CT image. Radiologists could observe vessels in the CT images during the biopsy procedure so that the risk can be decreased. The developed algorithm was tested through 20 groups of lung data and 16 groups of liver data. The results show that the fusion errors (mean ± standard deviation) were 2.35 ± 0.85, 2.08 ± 0.41, 2.31 ± 0.49, and 2.37 ± 0.62 mm for portal vein, hepatic vein, pulmonary artery, and pulmonary vein, respectively. The accuracy of this method was satisfied in clinical application

Efficacy of contrast-enhanced ultrasound-guided percutaneous core needle biopsy in anterior mediastinal masses. J Interv Med 2022; 5:159-165. [PMID: 36317148 PMCID: PMC9617154 DOI: 10.1016/j.jimed.2022.04.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 04/15/2022] [Accepted: 04/16/2022] [Indexed: 11/23/2022] Open
Abstract
Objective To evaluate the efficacy and safety of percutaneous core needle biopsy (PCNB) using ultrasound (US)-guided and contrast-enhanced ultrasound (CEUS)-guided procedures for anterior mediastinal masses (AMMs). Methods In total, 284 consecutive patients (166 men, 118 women; mean age, 43.0 ± 18.4 years) who underwent PCNB for AMMs were enrolled. Patients were divided into the US-guided group (n = 133) and the CEUS-guided group (n = 151). PCNB was performed using a core needle (16-gauge or 18-gauge). Internal necrosis, diagnostic yield, and diagnostic accuracy were compared between the two groups. Results The predominant final diagnosis of the cases in this study was thymoma (29.7%), lymphoma (20.5%), thymic carcinoma (13.3%), and germ cell tumour (13.3%), respectively. There was no significant difference in patient age, sex, number of percutaneous biopsies, or display rate of internal necrosis on conventional US between the two groups. The rate of internal necrosis of the lesions was significantly higher after contrast agent injection (72.2% vs. 41.7%; P < 0.001). The CEUS-guided group had a higher diagnostic yield than the US-guided group (100% vs. 89.5%, P < 0.001). There was no significant difference between the diagnostic accuracy of the CEUS-guided and US-guided groups (97.3% vs. 97.4%; P = 1.000). None of the patients experienced adverse reactions or complications after US-guided or CEUS-guided PCNB. Conclusions CEUS-guided PCNB can improve the diagnostic yield by optimizing the biopsy procedure.

Abstract
Background Adequate tissue sampling is fundamental for establishing a definitive diagnosis, assessing prognosis and tailoring therapy. Each of the methods for obtaining tissue (e.g., endoscopic, image guidance and surgical biopsies) results in a different diagnostic yield and complication rate profile. Objectives Present feasibility, and assess safety and efficacy of freehand transthoracic ultrasound‐guided core‐needle biopsies (USGNB) of thoracic lesions performed by pulmonologist. Methods A retrospective analysis study of ultrasound‐guided core‐needle biopsies of thoracic lesions performed at the Pulmonary Institute of Rabin Medical Center was conducted from September 2020 to October 2021. All core‐needle biopsies were performed under local anesthesia with guidance of Mindray TE7 2019 US system. Procedural variables including complications and pathological diagnostic yield were the primary end point. IRB 0671‐21‐RMC. Results In total 91 biopsy procedures were analyzed in38 females and 53 males, average age 71.1 years. Twenty‐three (25.3%) cases were lung lesions, 7 (7.7%) – mediastinal, 13 (14.3%) – chest wall, 27 (29.7%) – pleural, and 21 (23.1%) supraclavicular lesions. Average lesion size was 51.6 mm, the largest in the mediastinum and the smallest in supraclavicular locations (97.7mm and 28.0 mm, respectively). Overall pathological diagnostic yield was 90%, highest success in chest wall (100%) and lowest in mediastinal biopsies (71.4%). We had only one complication –hemothorax resolved by chest tube drainage‐ accounting for only 1.1% complication rate. Conclusion Safety and efficacy were demonstrated in freehand US‐guided core‐needle biopsy of thoracic lesions performed by pulmonologists. We suggest thoracic ultrasound and USG‐CNB be part of training and clinical practice in interventional pulmonology.

Abstract
INTRODUCTION Contrast-enhanced ultrasound is utilized in an increasing array of medical fields, including thoracic medicine. However, the technique is still relatively new and only sporadically mentioned in current guidelines and recommendations. The aim of this systematic review is to provide a literature overview and to critically appraise the current clinical applications of contrast-enhanced thoracic ultrasound (CETUS). MATERIALS AND METHODS A systematic literature search using major electronic databases and in accordance with PRISMA guidelines was performed. Studies with a primary focus on CETUS of thoracic disorders compared to a standard reference test were included. The QUADAS-2 tool was used for quality assessment of the studies. RESULTS The search identified 43 articles: 1 randomized controlled study, 6 non-randomized controlled studies, 16 non-randomized non-controlled studies, 5 case series, 10 single case reports, and 5 animal studies. The overall risk of bias was judged to be high. Diagnostic accuracy measurements of noninvasive applications of CETUS were only reported in a few studies and they were too dissimilar for meta-analysis. Six studies compared CETUS-guided versus ultrasound-guided transthoracic needle biopsy of thoracic masses. They individually reported a significant increase in diagnostic accuracy in favor of CETUS guidance but were too heterogeneous for meta-analysis. CONCLUSION The current literature on CETUS is overall heterogeneous with a few high evidence level studies, small study populations and a high risk of bias. CETUS-guided biopsy is the most frequent clinical application and increases diagnostic accuracy compared to ultrasound guidance by an average of 14.6 percentage points.

Abstract
Objective To retrospectively evaluate the safety and efficacy of percutaneous image-guided mediastinal mass core-needle biopsy. Patients and Methods Retrospective review of an institutionally maintained biopsy registry identified 337 computed tomography- or ultrasound-guided percutaneous mediastinal mass core needle biopsies between October 2002 and August 2017 in a single quaternary referral center. Mean patient age was 51 (range, 18 to 93) years. Procedural techniques, anticoagulation/antiplatelet therapy, and tumor anatomical characteristics were reviewed. Classification and gradation of complications was based on the Clavien-Dindo system. Diagnostic yield was defined as the ratio of diagnostic biopsy to all biopsies performed. Results Mean tumor size was 59.2 (range, 10 to 180) mm with 89.9% (n=303) of lesions located in the prevascular (anterior) mediastinum. There was a single major complication (0.3%) of a symptomatic pneumothorax requiring intervention. There were seven (2.1%) minor complications, including three bleeding complications. A transpleural approach was the only variable associated with an increased complication rate (P<.01). Forty-one (12.2%) patients had a biopsy performed while taking an antiplatelet/anticoagulant agent within the therapeutic window, with a single case (0.3%) associated with a minor bleeding complication. Of 18 (5.3%) procedures performed without cessation of anticoagulant/antiplatelet therapy, there were no bleeding complications. Of all 337 biopsies, 322 (95.5%) were diagnostic. None of the analyzed variables were significantly associated with a nondiagnostic biopsy. Conclusion Image-guided percutaneous core-needle biopsy of mediastinal masses is a safe procedure with high diagnostic yield. Further prospective studies are required to assess the complication profile in higher risk patients.

Abstract
OBJECTIVES To determine contrast enhancing features of mediastinal masses (ML) using transcutaneous contrast-enhanced ultrasound (CEUS). METHODS Retrospective analysis of n = 58 patients with histologically confirmed ML, which were examined in the period from October 2005 to February 2018 using transcutaneous B-mode ultrasound and CEUS. In n = 29 (50%) histological confirmation was performed by ultrasound guided core-needle biopsy. The lesions were evaluated using CEUS in regard to the enhancement pattern (hyper-, iso-, hypoenhancement, non-enhancement, homogenous, inhomogenous) compared to enhancement of the spleen as an in vivo reference. RESULTS N = 53 (91.4%) of ML were malignant (m) (lymphoma n = 36, metastasis n = 11, thymoma n = 2, teratoma n = 1, sarcoma n = 2, seminoma n = 1). In n = 5 (8.6%) cases there was a benign (b) histology (thyroid tissue n = 2, thymus residue n = 1, ganglioneurinoma n = 1, scar tissue: n = 1). In ultrasound, n = 53 (91.4%; (48 = m, 5 = b)) were hypoechoic, n = 5 (8.6%, (5 = m,0 = b)) hyperechoic. In CEUS, n = 35 lesions presented an arterial isoenhancement (60.3%; 33 = m, 2 = b). An arterial hypoenhancement had n = 21 (36.2%, (20 = m,1 = b)), and no enhancement showed n = 2 (3.5%, (0 = m, 2 = b) of the ML. A parenchymal isoenhancement was observed in n = 1 (1.7%, (1 = m, 0 = b)), a hypoenhancement in n = 54 (93.1%; 51 = m, 3 = b) of the patients and almost no enhancement in n = 3 ML (5.2%, (1 = m, 2 = b).) The enhancement was homogeneous in n = 26 (44.8%, (25 = m,1 = b)) cases, in n = 31 (53.5%, (28 = m,3 = b)) inhomogeneous and n = 1 (1.7%) benign lesion was exclusively cystic. CONCLUSION In CEUS, mediastinal tumor formations showed variable arterial enhancement, followed by parenchymal hypoenhancement (wash-out).

Abstract
Optimal assessment of the mediastinal masses is performed by a combination of clinical, radiological and often histological assessments. Image-guided transthoracic biopsy of mediastinal lesions is a minimally invasive and reliable procedure to obtain tissue samples, establish a diagnosis and provide a treatment plan. Biopsy can be performed under Computed Tomography, MRI, or ultrasound guidance, using a fine needle aspiration or a core-needle. In this paper, we review the image-guided strategies and techniques for histologic sampling of mediastinal lesions, along with the related clinical scenarios and possible procedural complications. In addition, image-guided mediastinal drainage and mediastinal ablations will be briefly discussed.

Abstract
Two-dimensional ultrasound (US) and color doppler flow imaging are associated with certain limitations in the preprocedural evaluation and design of the puncture path for biopsies of thoracic lesions, such as a poorly defined boundary between the tumor and the atelectatic lesions in central lung cancer with atelectasis. Contrast-enhanced ultrasound (CEUS) can be valuable in the preoperative evaluation of the biopsy site and in increasing the accuracy of the biopsy. The present study investigated the value of clinical application of CEUS in US-guided core needle biopsy (US-CNB) in improving the diagnostic accuracy in thoracic lesions. A total of 120 patients with first-stage thoracic lesions from the Affiliated Tumor Hospital of Guangxi Medical University who underwent US-CNB were recruited and randomnly assigned to a conventional US group (n=66) and a CEUS group (n=54). All patients underwent preoperative evaluation and US-guided puncture of thoracic lesions. The intergroup differences in sonographic features, biopsy duration, biopsy success rate and complications were assessed. The CEUS group had a higher rate of detection of necrotic tissue (40.7% vs. 16.7%; χ2=8.633; P=0.003) and change of initial puncture path (48.1%) compared with the US group. In central lung cancer with atelectasis, the ability to distinguish between tumor and atelectasis was higher in the CEUS group compared with the conventional US group (31.5 vs. 7.6%; χ2=11.336; P=0.001). In addition, the CEUS group had a higher puncture success (96.3 vs. 80.3%; χ2=6.946; P=0.008) and a lower complication rate (3.7% vs. 18.2%; χ2=6.041; P=0.014) compared with the US group. CEUS can identify necrotic areas and occult tumors within atelectatic lung tissue and can be used for guiding puncture biopsy of thoracic lesions to improve the diagnostic accuracy with greater comparative clinical utility than conventional US. Pre-biopsy CEUS is especially useful for patients undergoing repeated US-CNB and those with hypovascular lesions, atelectasis or necrosis.

Abstract
Background Given low incidence and high heterogeneity, the treatment strategies of anterior mediastinal masses (AMMs) are diverse based on pathology. The purpose of the study is to evaluate the usefulness of contrast-enhanced ultrasound (CEUS) in transthoracic biopsy of malignant AMMs when compared with that of ultrasound (US) alone and to screen lesions that are more suitable for CEUS evaluation and guidance. Methods We reviewed all the US- and CEUS-guided transthoracic core needle biopsy (CNB) of AMMs performed in National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between July 2013 and April 2019. A total of 68 patients (mean age 36 years; male-female ration 1.6:1) who were suspected with malignant AMMs were enrolled in the study. Among them, 20 patients received pre-biopsy CEUS examination (CEUS group); 48 patients underwent conventional US examination and guidance (US group). Demographic, radiologic, pathologic, medical records, and biopsy procedure details were retrospectively reviewed and compared between the two groups. Results The display of internal necrosis areas was significantly improved when compared with that of the conventional US (70%, 30%; P=0.008). Specifically, CEUS improved the diagnostic accuracy of US-guided transthoracic biopsy (95.0%, 79.2%; P=0.210) and especially for AMMs exceeding 10 cm (100%, 68.2%; P=0.040) and carcinoma (100%, 0%; P=0.048). The number of punctures in US group and CEUS group was 2.6 and 4.4 times, respectively (P<0.001). In case of similar number of punctures (1 to 3 times), CEUS improved diagnostic accuracy when compared to that of the conventional US (100%, 75%; P=0.486). The technical success rate was 100% (68/68). In both groups, patients did not exhibit symptomatic complications such as bleeding, pneumothorax, or hemoptysis after the biopsy. Conclusions The application of CEUS in transthoracic biopsy of malignant AMMs improved diagnostic accuracy when compared with conventional US and especially played more important role in lesions exceeding 10 cm and presumptive clinical carcinoma.

Abstract
Biopsy has been used to diagnose thoracic diseases for more than a century. Percutaneous needle biopsy plays a crucial role in the diagnosis, staging, and treatment planning for tumors in the lungs, thoracic wall, hilum, and mediastinum. With the continuous improvement in imaging techniques, the range of clinical applications for percutaneous needle biopsy is also expanding. It has become important to improve Chinese professionals’ and technicians’ understanding of percutaneous transthoracic needle biopsy (PTNB) in order to standardize operating procedures and to strengthen perioperative management. However, there is currently no Chinese expert consensus that provides systematic standardization and guidance for PTNB in clinical practice. The Committee of Chinese Society of Interventional Oncology (CSIO) of the Chinese Anti‐Cancer Association (CACA) initiated a Chinese multidisciplinary expert consensus on PTNB. The consensus includes image‐guided methods, indications, contraindications, multidisciplinary team recommendations, biopsy procedures, daytime/outpatient biopsy, complications, pathological examination, and management of negative results.

Abstract
The aim of this article is to provide an inventory of the use of contrast-enhanced ultrasound (CEUS) in relation to percutaneous interventional procedures. The article is structured into a systematic literature review followed by a clinical part relating to percutaneous CEUS-guided procedures. A literature search identified 3109 records. After abstract screening, 55 articles were analyzed and supplemented with pictorial material to explain the techniques. In conclusion, the best-evidenced indications for CEUS-guided interventions are biopsy and ablation of inconspicuous or B-mode-invisible tumors, intraprocedural ablation control and follow-up, as well as percutaneous transhepatic cholangiography and drainage procedures.

Contrast-Enhanced Ultrasound Improves the Pathological Outcomes of US-Guided Core Needle Biopsy That Targets the Viable Area of Anterior Mediastinal Masses. BIOMED RESEARCH INTERNATIONAL 2018; 2018:9825709. [PMID: 29581992 PMCID: PMC5822857 DOI: 10.1155/2018/9825709] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/07/2017] [Accepted: 12/18/2017] [Indexed: 01/13/2023]
Abstract
Based on the option that ultrasound-guided core needle biopsy (US-CNB) of the enhanced portion of anterior mediastinal masses (AMMs) identified by contrast-enhanced ultrasound (CEUS) would harvest viable tissue and benefit the histological diagnoses, a retrospective study was performed to elucidate the correlation between the prebiopsy CEUS and diagnostic yield of AMMs and found that CEUS potentially improved the diagnostic yield of AMMs compared with conventional US with a significant increase in the cellularity of samples. Furthermore, the marginal blood flow signals and absence of necrosis can predict the diagnostic yield of AMM. It was concluded that US-CNB of the viable part of AMMs, as verified by CEUS, was able to harvest sufficient tissue with more cellularity that could be used for ancillary studies and improve the diagnostic yield. And CEUS was recommended to those patients with AMMs undergoing repeated US-CNB, with the absence of marginal blood signals or presence of necrosis.
