Introduction. With biomedical imaging research increasingly using large datasets, it
becomes critical to find operator-free methods to quality control the data collected and the …

A major goal of the PET studies is to obtain a good quality and detailed image of an object
by the PET scanner, and so it depends on how well the scanner performs in image …

The aim of this study was to demonstrate the necessity of an off-centre uniformity
measurement during performance evaluation and acceptance testing of a positron emission …

This article briefly describes the event of a defective detector block in a daily quality
assurance scan/blank scan and insists on implementing guidelines to scan or not to scan in …

Positron emission tomography (PET) is based on the detection in coincidence of the two 511-
keV annihilation radiations that originate from β+-emitting sources, such as the patient …

Medicina Nuclear (MN) é uma especialidade médica na qual um composto químico
contendo um isótopo radioativo é administrado a um paciente por via oral, intravenosa ou …

In infants, brain 18F-FDG PET often requires sedation. To keep the sedation mild, the PET
acquisition time should be kept short. Therefore, calculated attenuation correction is often …

The scope of this article is to cover the synthesis and quality control procedures involved in
production of Fludeoxyglucose (18 F–FDG). The article also describes the cyclotron …

Several parameters associated with PET scanners are critical to good-quality image
formation, which include spatial resolution, sensitivity, noise, scattered radiations, and …

We report 2 separate cases with significant head motion causing apparent hypometabolic
and hypermetabolic cerebral activity on FDG PET/CT. Case 1 is a 57-year-old man with …
