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...

Neurolymphomatosis (NLY) is a type of rare disease with poor prognosis, characterized by infiltration of nerves, nerve roots and plexus. We report a case of 54-years old female patient non-diabetic and normotensive diagnosed with chronic lymphocytic leukemia presented with pain in the neck and arm and numbness in the ipsilateral hand. The patient underwent 18F fluorodeoxyglucose PET/...

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...

Purpose: To study the relationship between (FDG) uptake expressed quantitatively as standardized uptake values (SUVs) in normal breast tissues and breast density, age, menopausal status determined during dual-time point FDGPET/CT imaging. Materials and Methods: maximum and average SUVs were determined in two hundred eighty four patients (all females; mean age 55.5 ± 14.1 range 13-84 years, 115 ...

Thyroid incidentalomas are common findings during imaging studies including (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) for cancer evaluation. Although the overall incidence of incidental thyroid uptake detected on PET imaging is low, clinical attention should be warranted owing to the high incidence of harboring primary thyroid malignancy. We ...

objective(s): the present study was conducted to examine whether the standardized uptake value (suv) may be affected by the spatial position of a lesion in the radial direction on positron emission tomography (pet) images, obtained via two methods based on time-of-flight (tof) reconstruction and point spread function (psf). methods: a cylinder phantom with the sphere (30mm diameter), located in...
