Signet ring gallbladder carcinoma is a rare aggressive variant of mucinous adenocarcinoma with poor prognosis. Positron emission tomography/computed tomography (PET/CT) with Fluor18 deoxyglucose (F18-FDG) is a useful tool in the staging of gallbladder cancer. We report a 68 years old man with a surgically resected acute cholecystitis, whose biopsy was positive for signet ring cell gallbladder carcinoma. During surgery, locoregional lymph nodes, liver or peritoneal involvement were not detected. A PET/CT was performed for staging, finding multiple hypermetabolic lytic bone lesions...

BACKGROUND: Measures of tumour heterogeneity derived from 18-fluoro-2-deoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) scans are increasingly reported as potential biomarkers of non-small cell lung cancer (NSCLC) for classification and prognostication. Several segmentation algorithms have been used to delineate tumours, but their effects on the reproducibility and predictive and prognostic capability of derived parameters have not been evaluated. The purpose of our study was to retrospectively compare various segmentation algorithms in terms of inter-observer reproducibility and prognostic capability of texture parameters derived from non-small cell lung cancer (NSCLC) (18)F-FDG PET/CT images...

Sickle cell anemia (SCA) causes dysfunction of multiple organs, with pulmonary involvement as a major cause of mortality. Recently, there has been growing interest in the nitrogen single-breath washout (N2SBW) test, which is able to detect ventilation heterogeneity and small airway disease when the results of other pulmonary function tests (PFTs) are still normal. Thus, the objectives of the present study were to assess the heterogeneity in the ventilation distribution in adults with SCA and to determine the association between the ventilation distribution and the clinical, cardiovascular, and radiological findings...

A 78-year-old woman with hypertension had a positive fecal immunochemical test and underwent colonoscopy, which revealed a 4 mm sessile polyp (Paris type; 0-Is) in the transverse colon. Based on low magnification colonoscopy with narrow band imaging, the polyp was Type 2 according to the NBI International Colorectal Endoscopic classification, diagnosed as an adenoma, and then resected via cold snare polypectomy (CSP). Five days after CSP, she complained of right-sided abdominal pain. Abdominal CT showed focal wall thickening of the transverse colon and focal infiltration of tissues surrounding the transverse colon...

Prompt and accurate diagnosis is the foundation of acute ischaemic stroke care. Multiple positive endovascular thrombectomy trials in ischaemic stroke patients with large vessel occlusions have further emphasised this but also added complexity to treatment decisions. CT angiography is now routine for patients who present with an acute stroke syndrome around the world. Members of the neurology and stroke teams (rather than radiologists) are often the first doctors to lay eyes on the CT images and are best equipped to integrate the clinical picture with the imaging findings...

PURPOSE: Post-implant CT-scanning is an essential part of permanent prostate brachytherapy. However, the evaluation of post-implant CT dosimetry is not straightforward due to the edema that can modify the dose to the prostate and to the organs at risk. The aim of this study is to evaluate the impact of the timing of the post-implant CT-scan on the dosimetric results and to verify if the Day 0 scan findings can predict Day 50 scanning. METHODS: 136 consecutive patients who received monotherapy with I-125 implants were selected for this study...

This study was designed to explore the underlying mechanism of p-coumaric acid (CA), a dietary polyphenol in adjuvant-induced arthritis (AIA) rat model with reference to synovitis and osteoclastogenesis. Celecoxib (COX-2 selective inhibitor) (5 mg/kg b.wt) was used as a reference drug. CA remarkably suppressed the paw edema, body weight loss and inflammatory cytokine and chemokine levels (TNF-α, IL-1β, IL-6, and MCP-1) in serum and ankle joint of arthritic rats. Consistently, CA reduced the expression of osteoclastogenic factors (RANKL and TRAP), pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, and IL-17), and inflammatory enzymes (iNOS and COX-2) in arthritic rats...

INTRODUCTION: Postmortem CT angiography is the method of choice for the postmortem imaging investigations of the cardiovascular (CV) system. However, autopsy still remains the gold standard for CV measurement. Nevertheless, there are not any studies on CV measurements on the multi-phase postmortem angiography (MPMCTA) which includes comparisons with autopsy. Therefore, the aim of this study is to compare CV measurements between the native CT scan and the three phases of the MPMCTA to find out which of these modalities correlate the best with autopsy measurements...
