From: 68Ga-PSMA-11 PET/MRI: determining ideal acquisition times to reduce noise and increase image quality

Lesion detectability increased as acquisition time increased, and for all acquisition times, lesions with SUVmax ≥ 7.5 were more detectable compared with lesions with SUVmax < 7.5, though this difference narrows at longer acquisition times. This graph demonstrates that lesions with mild uptake need longer acquisition times to have similar detectability as lesions with intense uptake (p < .001)
