Head-to-head comparison of image quality between brain ¹⁸F-FDG images recorded with a fully digital versus a last-generation analog PET camera.

ABSTRACT:

Background

The quality of phantom images was previously shown to be higher on digital (Vereos Philips®) compared to analog PET (Ingenuity Philips®) cameras. This study aimed to determine the extent to which this difference still remains significant on normal brain ¹⁸F-FDG PET images.

Methods

Relative noise and contrast as well as border sharpness (a spatial resolution index) of central (striata) and peripheral (occiput) gray-matter structures were compared between 10 sets of normal brain ¹⁸F-FDG PET images recorded and reconstructed on digital and analog last-generation PET cameras, together with a subjective visual analysis of image quality provided by experienced physicians.

Results

Compared with analog PET, digital PET provided marked improvem
