چکیده

False-positive results on combined positron emission tomography/computed tomography can complicate detection and surveillance of head and neck cancers. We present a rare case of false-positive contralateral [18F]-2-fluoro-2-deoxy-D-glucose tongue uptake after hypoglossal nerve paralysis caused by squamous cell carcinoma originating from the base of the tongue.

A Comparative Study of the Construction of Positron Emission Tomography/Computed Tomography Facilities in Three South African Hospitals

Introduction: Development of higher energy modalities such as positron emission tomography/computed tomography (PET/CT), has led to more complex shielding problems. This is due to several factors, such as the radiopharmaceutical relatively high-administered activity, high patient throughput, and high energies of 511 kilo-electron volt (keV) positron annihilation photon...

Detection of Alzheimer\\\\\\\'s Disease using Multitracer Positron Emission Tomography Imaging

Alzheimer's disease is characterized by impaired glucose metabolism and demonstration of amyloid plaques. Individual positron emission tomography tracers may reveal specific signs of pathology that is not readily apparent on inspection of another one. Combination of multitracer positron emission tomography imaging  yields promising results. In this paper, 57 Alzheimer's disease neuroimaging ini...

FFDG positron emission tomography/computed tomography to judge benign or malignant colorectal hypermetabolic lesions

The lengthy and tortuous journey, the unstable positioning of the colon and rectum, and variations in intestinal wall thickness during intestinal peristalsis have brought about significant difficulties for computed tomography (CT) diagnosis. Glucose metabolism is unstable in the colon and rectum, and smooth muscle peristalsis, gland secretion, spasms, and inflammation can also cause abnormal me...
