Therefore, a more accurate risk assessment tool is required. We investigated the predictive value of two new volume-based parameters determined from baseline 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT), baseline total metabolic tumor volume (TMTV) and total lesion glycolysis (TLG), in 45 patients with high-tumor-burden FL who underwent baseline PET/CT.

Methods: Preoperative PET/CT findings (pStage IB-III 182 patients) and pathological diagnoses after surgical resection were evaluated. Using PET/CT images to determine the standardized uptake value (SUV) ratio, the SUV of a contralateral hilar lymph node (on the side of the chest opposite to the primary tumor) was measured simultaneously.
Objectives: For thymic epithelial tumors, simple contact with adjacent structures does not necessarily mean invasion. The purpose of our study was to develop a simple noninvasive technique for evaluating organ invasion using routine pretreatment computed tomography (CT).
Methods: This retrospective study analyzed the pathological reports on 95 mediastinal resections performed between January 2003 and June 2020.
Background: Uterine adenomyosis is a benign disease, common among women in their 40 and 50 s, characterised by ectopic endometrial tissue in the uterine myometrial layer. Adenomyosis causes infertility and has a negative effect on the outcomes of in vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI) embryo transfer (ET) cycles. It has also been reported to have different characteristics depending on the adenomyotic lesion localisation.

Purpose: To investigate the effectiveness of postmortem computed tomography in the diagnosis of drowning, focusing on the comparison of fresh water and salt water cases using three-dimensionally (3D) reconstructed data.
Materials And Methods: We examined features of drowning in 25 fresh water drowning cases (FWDCs; 13 men, 12 women; mean age 73.1 years; range 43-95 years), and compared these with 12 salt water drowning cases (SWDCs; 5 men, 7 women; mean age 66.
Purpose: To evaluate CT density of liver changes between before and after amiodarone administration.
Materials And Methods: Twenty-five patients underwent non-enhanced CT including the liver before and after amiodarone administration. We set regions of interest (ROIs) at liver S8, spleen, paraspinal muscle, and calculated average CT density in these ROIs, then compared CT density between liver and other organs.
Background: The aim of the present study was to use surgical and histological results to develop a simple noninvasive technique for improving nodal staging using preoperative PET/CT in patients with resectable non-small cell lung cancer (NSCLC).
Methods: Preoperative PET/CT findings (163 patients) and pathological diagnoses after surgical resection were evaluated. Using PET/CT images, lymph node section area (SA), the maximum standardized uptake value (SUV), SA of SUV ≥2.
Introduction: Ultrasound-guided intranodal lipiodol lymphangiography (LAG) from the groin is a recently introduced technique for diagnosing and treating postoperative chylothorax. The benefits of this technique include reduced technical difficulty and shorter procedure duration, as compared to traditional pedal LAG. Although these benefits may eventually increase utilization of intranodal LAG, reports are still few.

However, there are particular pancreatic tumors having various grades of malignancy such as intraductal papillary mucinous neoplasm (IPMN) or pancreatic neuroendocrine tumor. We examined whether the cut-off value of maximum standardized uptake value (SUVmax) determined by pancreatic ductal cancers is also applicable for other pancreatic tumors.

Methods: A total of 16 patients with endoscopically proven high-risk GVs treated using combined B-RTO with ET+LPD and EIS with CA between January 2007 and July 2012 were enrolled.
Results: Twelve cases included GVs involving both the cardia and fundus, two cases included fundal varices and two cases included cardiac varices.
Although spine injuries are not always detectable on postmortem computed tomography (PMCT), spinal hyperostosis, an important risk factor for spine injury, is relatively easily detectable on PMCT. We therefore examined the utility of the detection of spinal hyperostosis on PMCT as an indicator of spine injury. Full-body PMCT images of 88 autopsy cases with a bruise on the face or forehead but no identifiable skull fracture were reviewed prior to autopsy for the identification and classification of spinal hyperostosis.

Methodology: Forty patients with gallbladder lesions (22 patients with cancer, 7 patients with adenoma, and 11 patients with inflammatory disease) were enrolled in this study. All patients underwent high-b value DWI, and the ADC value was measured.
Purpose: This study investigated the actual rate or extent of lymph node metastasis or the survival outcomes among patients that underwent esophagectomy with lymph node dissection after ESD for clinical mucosal, but pathological submucosal, esophageal cancer.
Methods: Seventeen patients that received esophagectomy with two- or three-field lymph node dissection as additional treatment after ESD for clinical mucosal, but pathological submucosal, esophageal cancer between 2006 and 2010 were analyzed. The rate and extent of lymph node metastasis and the patient outcomes were determined.
Background: In cases of thoracic esophageal cancer, multidirectional lymphatic flow from the tumor means that lymph node metastasis can occur in an area extending from the neck to the abdomen. To validate a method for limiting the performance of three-field lymphadenectomy only to patients who need it, we carried out a prospective study in which superparamagnetic iron oxide (SPIO)-enhanced lymphatic mapping was used to determine whether to perform neck lymph node dissection in patients with submucosal thoracic esophageal cancer.
Methods: A total of 22 patients with clinically submucosal thoracic squamous cell esophageal cancer, without neck lymph node metastasis, were enrolled.
