Abstract
LAFOV PET presents an excellent sensitivity, offering the ability of high-quality extra short images. We assess through a case report the additional value of performing 68 GA-PSMA-11 PET/CT dynamic acquisitions on an LAFOV PET system to improve discrimination between pathological uptakes, such as lymph nodes, from urinary physiological uptake. We performed a single-bed 4-minute list-mode acquisition, reconstructed in 4 frames of 1 minute, providing a dynamic visualization of 68 GA-PSMA-11 urinary ureteral excretion over time. This additional reconstruction is easy to implement in clinical practice, requiring no additional acquisition time or radiological exposure.
