Abstract
PURPOSE To evaluate the accuracy of contrast-enhanced mammography (CEM) and magnetic resonance imaging (MRI) in the assessing radiological response to primary systemic therapy (PST). METHOD Prospective study between February 2021 and October 2022. Women with breast cancer and indication of PST were enrolled. CEM and MRI were performed before and after PST, and the findings, including size and radiological response pattern, were compared with the size of the residual lesion measured in surgical specimens and its Miller-Payne classification (considered the gold standard). Two of four independent radiologists, with 2 years of CEM experience and 10 years of MRI experience, reviewed the images while being blinded to the results of the other technique. The agreement between measurements was evaluated using the Pearson correlation coefficient (r) and Lin's coefficient. RESULTS Forty-eight women with breast cancer who required PST were enrolled in the study, with a mean age of 57.21 ± 10.14 years. A total of thirty-three participants (68.75 %) completed the study. The correlation between CEM and MRI measurements was high before PST (r: 0.97), and local staging was identical for 45 out of 48 patients. MRI demonstrated better accuracy in predicting residual tumor size than CEM, with Lin's coefficient 0.91 and 0.73, respectively. However, no significant differences were observed in predicting response to therapy. Both methods tended to overestimate the size and degree of response in our study, with mean overestimations of 2.87 mm in CEM and 0.51 mm in MRI. CONCLUSION CEM was found to be as accurate as MRI in predicting response to PST, indicating its potential as an alternative imaging technique, but further research is necessary.

Abstract
OBJECTIVE To assess the utility of intraoperative indocyanine green video angiography (ICG-VA) during microsurgical resection of arteriovenous malformations (AVMs). METHODS Data of the 24 patients, who were surgically treated for AVM using intraoperative ICG-VA, were reviewed retrospectively. Postoperative digital subtraction angiography (DSA) was performed in all patients before they regained consciousness and became fully awake, and the results were compared with those obtained with intraoperative ICG-VA. A scheduled DSA was performed in all patients in the third, sixth, and 12th postoperative months as well. RESULTS Authors retrospectively analyzed the records of intraoperative ICG-VA application of all 24 patients. Though the exposures were limited and the image qualities were poor at higher magnification on the surgical microscope within deep surgical fields, the AVM niduses, feeding arteries, draining veins, and their relations to normal vasculature were observed precisely with ICG-VA in all the procedures. Furthermore, the visualization was not qualified enough to identify these pathological vascular structures accurately before evacuating and irrigating the layer of blood clots that obscure the view in patients who presented with hemorrhage. In a patient in our series, a residual nidus in the tail of the caudate nucleus was detected with immediate postoperative DSA which was not revealed by terminal assessment with final intraoperative ICG-VA. CONCLUSIONS Intraoperative ICG-VA is particularly effective in the identification of the feeder, nidus, and drainer and in the assessment of the flow dynamics of the nidus in cerebral AVM surgery. It may be a quick and safe technique for intraoperative imaging of the angioarchitecture of superficial AVMs, but it may be less helpful for deep-seated lesions. Furthermore, this method alone may not be useful in the identification of residual disease or improvement of the clinical outcomes. DSA has remained the gold standard for confirming AVM obliteration. Despite the technical limitations associated with ICG-VA, a combination of intraoperative ICG-VA and immediate postoperative DSA may advance the safety and efficacy of AVM surgery.

Abstract
BACKGROUND Metastasis to the ovary from nongynecologic organs accounts for 9% of all ovarian malignancies. Although the most common nongynecologic primary site of ovarian metastasis is the gastrointestinal tract, metastasis from other sites to the ovary is not uncommon. Differential diagnosis of primary and metastatic ovarian tumors is important; otherwise, appropriate treatment cannot be determined. Furthermore, an optimal treatment strategy for ovarian metastasis from nongynecologic primary sites still needs to be explored. METHODS One hundred seventy-seven patients with ovarian metastasis from nongynecologic primary sites admitted to Peking Union Medical College Hospital between May 2005 and May 2018 were retrospectively evaluated. RESULTS The mean age was 48 years (range, 18-83). Approximately 60% of patients were premenopausal women. The two most common nongynecologic primary sites of ovarian metastasis were the colorectum (68 cases) and stomach (61 cases). In addition to the most common symptoms of abdominal distension (39.0%), abdominal pain (37.9%), and ascites (27.7%), 18.1% of patients presented with abnormal uterine bleeding. Half of the patients who tested serum CA-125 preoperatively had elevated CA-125 levels within the range of 35 U/ml to 200 U/ml. More than 70% of synchronous ovarian metastases were preoperatively misdiagnosed as primary ovarian cancer. Of all included cases, 56.5% achieved optimal cytoreductive surgery (the diameter of the largest residual lesion < 2 cm). The overall 5-year survival rate and median survival time were 10% and 20 months, respectively. The primary site, optimal cytoreductive surgery, tumor differentiation, and postoperative adjuvant treatment were identified as prognostic indicators. CONCLUSIONS The colorectum and stomach are the most common nongynecologic primary sites of ovarian metastasis. Synchronous ovarian metastasis is easily misdiagnosed as primary ovarian cancer. Optimal cytoreductive surgery and postoperative adjuvant treatment can be performed to confer survival benefit in selected patients.

Abstract
Magnetic resonance imaging (MRI) is the preferred imaging method for evaluating treatment response in spine infection. However, there are still no definite correlation between follow-up MRI findings and clinical status. Recently, Fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET) shows great potential as diagnostic and monitoring options. Simultaneous 18F-FDG PET/MRI makes us to expect a huge synergic effect on diagnosis and evaluation of treatment response with metabolic and anatomical advantages in spine infection. We introduce an application of 18F-FDG PET/MRI for evaluating residual lesion in the patient with pyogenic spine infection.

Abstract
BACKGROUND In order to optimize postoperative therapy in patients with Crohn's disease (CD), it is important to detect endoscopic recurrence preceding clinical recurrence. However, we have little knowledge about how high the rate of residual lesions is and whether these lesions have an influence on postoperative course or not. AIMS To assess residual lesions in small bowel immediately after surgery. METHODS Capsule endoscopy (CE) was performed immediately after surgery (< 3 months), and endoscopic activity was assessed using the Lewis score (LS) composed of the highest tertile score (in first, second, and third tertile) and the stenosis score (in whole small intestine). The relationship between these residual lesions and postoperative clinical recurrence was prospectively evaluated. RESULTS After assessing patency using a patency capsule, CE was performed in 25 patients. The mean LS was 751.3, and 84.0% (21/25) had endoscopic activity. These lesions were detected by preoperative examinations in 0% and by a serosal side view during surgery in 16.0%. Regarding the cumulative clinical recurrence rate according to endoscopic severity (normal, mild, and moderate-to-severe) immediately after surgery, no significant difference was found. However, comparing groups divided according to the highest tertile score, the cumulative clinical recurrence rate was significantly higher in the group with the highest third tertile score. Furthermore, patients with ulcers in the third tertile had a significantly higher recurrence rate. CONCLUSIONS Many cases with CD had endoscopic activity immediately after "curative" surgery. These residual lesions, especially in the distal small intestine, were associated with postoperative clinical recurrence.

Abstract
Preventive percutaneous coronary intervention (PCI) for non-culprit lesions after primary PCI remains controversial in patients with acute coronary syndrome (ACS). We analyzed whether PCI for non-culprit lesions would be associated with a better long-term prognosis in very elderly (≥85 years) patients. This study included 91 consecutive patients with ACS (mean age, 88.2 ± 3.0, 52 % male). We investigated the association of residual lesions with 1-year mortality. Culprit lesions affected the left anterior descending artery (LAD) in 50 patients, the left circumflex artery (LCx) in 29, and the right coronary artery (RCA) in 31. Residual lesions affected LAD in 20 cases, LCx in 22, and RCA in 21 patients. Residual lesions in LAD were associated with a higher 1-year mortality (p = 0.013), whereas residual lesions in LCx or RCA were not (p = 0.547 and 0.473, respectively). A Cox regression model demonstrated that patients with residual lesions in LAD had an increased risk of 1-year mortality compared with those without residual lesions (hazard ratio, 2.39; 95 % confidence interval, 1.16-4.96; p = 0.019). Therefore, the option to not treat residual lesions in LAD of patients with PCI may be associated with a higher 1-year mortality. Further studies are needed to confirm these findings.

Abstract
AIM To evaluate the ability of (18)F-fluorodeoxyglucose positron emission and computed tomography ((18)F-FDG PET/CT) in restaging of hepatocellular carcinoma (HCC) after treatment. METHODS We reviewed a database of the diagnostic performance of (18)F-FDG PET/CT scan for patients with HCC following local or regional treatment. The database consisted of (18)F-FDG PET/CT information of 21 male and 4 female (age range, 27-81 years; mean age, 51.6 years) patients who had received surgical resection and/or interventional treatments and then underwent (18)F-FDG PET/CT scan. All patients had received enhanced CT scan of the liver two weeks before or after the (18)F-FDG PET/CT scan. Intrahepatic recurrence and/or extrahepatic metastases were confirmed by histological analysis or clinical and imaging follow-up. The accuracy of (18)F-FDG PET/CT study was determined by histopathological results or by clinical and imaging follow-up. RESULTS (18)F-FDG PET/CT was abnormal in 19 of the 25 (76.0%) patients. In detecting HCC recurrence, (18)F-FDG PET/CT scored 17 true positives, 5 true negatives, 2 false positives and 1 false negative. The sensitivity, specificity and accuracy of (18)F-FDG PET/CT in detecting HCC recurrence was 89.5%, 83.3% and 88%, respectively. (18)F-FDG PET/CT had an impact on management of these patients by settling the problem of an unexplained increase in alpha-fetoprotein after treatment (14 patients), by monitoring response to the treatment and guiding additional regional therapy (12 patients), by identifying extrahepatic metastases (10 patients), by identifying tumor growth or thrombosis in the portal vein (6 patients), or by guiding surgical resection of extrahepatic metastases (2 patients). CONCLUSION Our results suggest that whole body (18)F-FDG PET/CT may be useful in the early evaluation of residual, intrahepatic recurrent or extrahepatic metastatic lesions and able to provide valuable information for the management of HCC recurrence.
