TL;DR
Open-source BSREM showed task-, region, and count-dependent behavior, supporting task- and count-specific parameter selection before clinical application, and showed reduced left-putaminal uptake remained underestimated, and putaminal asymmetry moved further from their theoretical values.
This study identified settings associated with improved quantitative metrics within the evaluated parameter space, with potential implications for quantitative imaging requiring clinical validation, and identified candidate optimised StarGuide/Q.Clear reconstruction parameters for 123I and 177Lu imaging.

Whether Q.Clear and VUE Point FX (VPFX) reconstructions obtained from the same brain PET acquisition are quantitatively interchangeable is investigated to characterise the regional, reference-region and noise-texture dependence of any differences.

Under matched reconstruction conditions, 18F retained superior intrinsic resolution and contrast recovery, whereas longer acquisitions mainly reduced noise and could not overcome the physical resolution limitations of 68Ga.

This study investigated the relationship between body size, administered activity, and image quality (IQ) using two patient-like phantoms representing normal and obese body profiles, and demonstrated the count rate capabilities up to and beyond the saturation limit.
