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

摘要

Lesion detectability (mean Likert Score) increased as acquisition time increased (left, p < .001), and there was no significant difference between 7 and 10 min of acquisition time. For acquisition times less than 10 min per bed position, lesions ≥ 5 mm were more detectable compared with lesions < 5 mm in size (right). This graph demonstrates that small lesions need longer acquisition times to have the same detectability as large lesions (p = .036)
