Colorectal cancer represents the second most common malignancy worldwide, with approximately one million newly diagnosed cases each year, and is the fourth leading cause of cancer mortality. This article provides an overview of the role of FDG (fluorodeoxyglucose) PET (positron emission tomography) CT (computed tomography) for assessment in patients with colorectal cancer. A summary of key lear...

18F-FDG is formed through radiochemical synthesis from cyclotron-produced 18F (K. Breslow, written communication, June 2000). Production of 18F is through proton bombardment of enriched 18O-water. 18F-fluoride is bound to 1,3,4,6-tetra-O-acetyl-2-O-trifluoromethanesulfonyl-Dmannopyranose (mannose triflate) under conditions of a stereospecific second-order nucleophilic substitution reaction, whi...

A 71-year-old woman was referred to our tertiary care center for evaluation of asymptomatic recurrence of primary hyperparathyroidism. As per our protocol, the patient underwent neck/mediastinum F-fluorocholine (FCH) positron emission tomography-computed tomography (PET-CT) for localization. In our institution, FCH PET-CT is performed in patients with hyperparathyroidism and negative convention...

Submit Manuscript | http://medcraveonline.com Malignant peripheral nerve sheath tumor (MPNST) is a rare tumor group seen in neurofibromatosis type I patients. There are few reports on PET-CT imaging of this rare entity in literature. FDG PET-CT is a part of the conventional work-up among a variety of cancer patients. Nevertheless, in certain clinical situations PETCT may be of great significanc...

TO THE EDITOR: We read with great interest the recent article by Cheung et al. on the utility of 11C-acetate/18F-FDG PET/CT for clinical staging and appropriate selection of patients with hepatocellular carcinoma (HCC) for liver transplantation based on the Milan criteria (1). The authors of this study were able to show the strength of PET/CT over dynamic contrast-enhanced CT to detect HCCs (pa...
