Positron emission tomography/computed tomography (PET/CT) integrated with 2-[18F]fluoro-2-deoxy-D-glucose (FDG) is a useful tool for acquisition of both glucose metabolism and anatomic imaging data, as only a single device and one diagnostic session is required, thus opening a new field in clinical oncologic imaging. FDG-PET/CT has been successfully used for initial staging, restaging, assessment of early treatment response, evaluation of metastatic disease response, and prognostication of intestinal cancer as well as various malignant tumors...

  A woman in her thirties was diagnosed as Takayasu's arteritis (TAK) by dilatation, wall thickness of her abdominal aorta in contrast-enhanced computed tomography. Although she didn't have any subjective bowel symptoms, fluorodeoxyglucose (FDG)-positron emission tomography (PET) also revealed uptake of FDG in descending colon, and colonoscopy revealed aphthous colitis. After the start of steroid therapy, both arteritis and colitis were improved. FDG-PET can detect TAK and inflammatory bowel diseases at an early stage...

Tumoral calcinosis is a benign condition characterized by periarticular calcified lesions that is frequently observed in patients with chronic renal failure. Tumoral calcinosis often presents with subcutaneous masses and joint swelling. We present a case of tumoral calcinosis with dramatically increased 18F-fluoro-2-deoxy-d-glucose (18F-FDG) uptake on positron emission tomography/computed tomography (PET/CT) that mimicked lymphoma or lymph node metastases.

A 65-year-old woman with metastatic lung cancer was referred for CT-guided cryoablation of a right adrenal metastasis. For cryoablation, probes were placed into the adrenal region. FDG PET/CT 3 months later showed new activity in hepatic segment 6 initially suspected to be metastasis. Proximity of the hepatic lesion to the adrenal metastasis was a strange coincidence and prompted review of imaging from the cryoablation. CT showed the probe entered the liver, and postablation image demonstrated injury to the liver adjacent to the adrenal metastasis...

INTRODUCTION: The prevalence of incidental 18 F-fluorodeoxyglucose (FDG)-avid findings on positron emission tomography-computed tomography (PET/CT) has been extensively described. Few studies, however, have assessed the prevalence and significance of non-FDG-avid findings; pathology that is identified on review of the low-dose, non-contrast CT. The aim of this study was to determine the overall prevalence of non FDG-avid incidental findings on PET/CT and the prevalence of 'clinically significant' non FDG-avid pathology...

The risk factors and potential practice implications of radiation-induced pleural effusion (RIPE) are undefined. This study examined lung cancer patients treated with thoracic radiation therapy (TRT) having follow-up computed tomography (CT) or 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT. Increased volumes of pleural effusion after TRT without evidence of tumor progression was considered RIPE. Parameters of lung dose-volume histogram including percent volumes irradiated with 5-55 Gy (V5-V55) and mean lung dose (MLD) were analyzed by receiver operating characteristic analysis...

Objective: MET is a member of the receptor tyrosine kinases. Several MET-targeting inhibitors and antagonistic antibodies have shown promising data in clinical trials of lung adenocarcinoma. Finding noninvasive diagnostic tools to estimate the status of MET is helpful in clinical practice. 18F-fluorodeoxyglucose positron emission tomography/computerized tomography (18F-FDG PET/CT) has been used routinely for the diagnosis and staging of tumors. However, the relationship between MET expression and 18F-FDG uptake has not been investigated yet...
