Investigation of the effectiveness of no-reference metric in image evaluation in nuclear medicine.

ABSTRACT:

Background

In nuclear medicine, normalized mean square error (NMSE) is widely used for image quality evaluation and machine adjustment. However, evaluating clinical images in nuclear medicine using NMSE necessitates acquiring a reference image, which is time consuming and impractical. Therefore, it is necessary to explore no-reference metrics, such as perception-based image quality evaluator (PIQE) and natural image quality evaluator (NIQE), as alternatives for evaluating the quality of clinical images used in nuclear medicine.

Purpose

To examine whether no-reference metrics can be applied to image quality evaluations for clinical images in nuclear medicine.

Methods

Images of the Hoffman Brain Phantom containing 18F-fluoro-2-deoxy-D-glucose (FDG) were obtained using B
