The present study evaluates the accuracy of computed tomographic (CT) scan and positron emission tomography with (18)F-fluorodeoxyglucose (FDG-PET)/CT for the quantification of peritoneal carcinomatosis (PC) in patients undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Data were retrospectively collected for 58 patients, who were considered for CRS an...

A 35-year-old woman, already treated with surgery, chemotherapy, and radiotherapy for a ductal carcinoma of the left breast, underwent an (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) scan for an increase of the serum markers carcinoembryonic antigen (CEA) and cancer antigen 15.3 (CA15.3). The scan showed multiple FDG-avid lesions in the liver and ...

UNLABELLED (18)F-FDG PET plays an important role in the evaluation of patients with lung malignancies but can lead to false-positive and false-negative results. Very little is known about (18)F-FDG PET scanning in amyloidosis. METHODS A computer-assisted search of medical records was conducted to identify subjects with pulmonary amyloidosis (confirmed by biopsy) who were seen at the Mayo Clin...

BACKGROUND The study aimed to evaluate the use of positron emission tomography/computed tomography (PET/CT) with (68)Ga-PRGD2 as the tracer for imaging of synovial angiogenesis in patients with rheumatoid arthritis (RA). METHODS Twenty untreated active patients with RA underwent (68)Ga-PRGD2 PET/CT and (18)F-FDG PET/CT before treatment; two patients with osteoarthritis served as controls. Amo...

Fig. 1. The PET/CT scan was performed 70 min after intravenous injection of 363 MBq (9.8 mCi) of F-FDG. Maximum intensity projection (A), axial PET (B, E), PET/CT fusion (C, F) and CT (D, G) at level of upper abdominal and thoracic images showed a large right adrenal mass (60 × 45 mm dimensions, 44 HU) without any significant FDG uptake (SUVmax: 1.8) (open arrows) and increased FDG uptake in a ...

We present here the case of a 40-year-old woman with a greater than 10 year prior history of bilateral breast silicone injection and saline bag implantation. Bilateral palpable breast nodules were observed, but the ultrasound scan was suboptimal and the magnetic resonance imaging showed no gadolinium-enhanced tumor. The (18)F-FDG PET/CT scan showed a hypermetabolic nodule in the left breast wit...

PURPOSE The aim of this study was to evaluate the effect of combined (68)Ga and (18)F-FDG PET/CT on treatment management for patients with pancreatic neuroendocrine tumor (PNET). METHODS Between January 2012 and April 2014, 49 consecutive patients with a cytologically and/or histologically proven diagnosis of PNET underwent combined (68)Ga and (18)FDG PET/CT on the same day. RESULTS The stu...

The aim of this retrospective analysis was to describe our clinical experience for fluorine-18 (F) fluorodeoxglucose (FDG) positron emission tomography/computed tomography (PET/CT) in patients with soft tissue and osseous sarcoma. Total of 26 F-FDG PET/CT scans were evaluated in 17 patients (7 osteosarcoma, 5 Ewing’s sarcoma, 3 uterine sarcoma and 2 rhabdomyosarcoma) in different stages of dise...

UNLABELLED This study was designed to compare tumor (18)F-FDG uptake between a single 20-s acquisition of deep-inspiration breath-hold PET/CT and free-breathing PET/CT for lung cancer. METHODS Before the clinical study, a phantom study was performed to determine the optimum breath-hold time for the PET scan. We studied 47 patients with lung cancer who underwent free-breathing PET/CT with the ...

We report a case of a multicentric form of Castleman's disease with multiple lymph nodes showing intense FDG uptake on whole body scan mimicking non-Hodgkin's lymphoma. In this report, the patient had multiple cervical, mediastinal, hilar, retroperitoneal and abnormal lymph nodes in the groin. (18)F-fluorodeoxyglucose positron emission tomography/computed tomography was performed before tissue ...
