Role of fluoroethyl tyrosine positron emission tomography-computed tomography scan in differentiating ewing's sarcoma from osteomyelitis

World Journal of Nuclear Medicine, 2019
Ewing's sarcoma is a kind of undifferentiated reticulocytic sarcoma, which was first reported in 1921 by James Ewing. It is difficult to differentiate Ewing's sarcoma from osteomyelitis on computed tomography (CT) and X-ray and hence cytological ...

Xanthogranulomatous cholecystitis mimicking gallbladder cancer on 18F-fluorodeoxyglucose positron emission tomography/computed tomography scan

World Journal of Nuclear Medicine, 2021
The abnormal thickening of the gallbladder (GB) wall can be caused by a malignant condition like gallbladder carcinoma or by benign lesions such as chronic cholecystitis or xanthogranulomatous cholecystitis (XGC).

Optimisation of CT protocols in PET-CT across different scanner models using different automatic exposure control methods and iterative reconstruction algorithms

EJNMMI Physics, 2021
Background A significant proportion of the radiation dose from a PET-CT examination is dependent on the CT protocol, which should be optimised for clinical purposes.

Practical issues and limitations of brain attenuation correction on a simultaneous PET-MR scanner

EJNMMI Physics, 2020
Background Despite the advent of clinical PET-MR imaging for routine use in 2011 and the development of several methods to address the problem of attenuation correction, some challenges remain.

FDG-PET/CT in lymphoma

Indian Journal of Radiology and Imaging, 2013
Lymphomas are a heterogeneous group of diseases that arise from the constituent cells of the immune system or from their precursors. 18F-fludeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT) is now the cornerstone of staging

Cessation of anti-VLA-4 therapy in a focal rat model of multiple sclerosis causes an increase in neuroinflammation

EJNMMI Research, 2019
Background Positron emission tomography (PET) can be used for in vivo evaluation of the pathology associated with multiple sclerosis. We investigated the use of longitudinal PET imaging and the 18-kDa translocator protein (TSPO) binding radioligand [18F ...
