NETs lesions can be difficult to characterize with conventional anatomic imaging (CT and MRI). Functional imaging techniques, and especially PET imaging, are very useful for detecting small neuroendocrine tumors that would not be seen with other techniques. The role of nuclear medicine in the localization, staging, restaging, treatment and monitoring of neuroendocrine tumors (NETs) has become progressively more relevant due to: the availability of tracers on new targets, tracers for positron emission tomography (PET); the development of cyclotrons and generators that allow this availability; as well as to hybrid systems (SPECT/CT, PET/CT and PET/MRI) that, by joining the functional and anatomical image, improve the quality of the images.

Early-phase 18F-florbetaben PET/CT has been proposed as a surrogate of 18F-FDG PET/CT providing information related to regional brain perfusion. We report the case of a 61-year-old woman referred to the cognitive impairment unit for study, preliminary diagnosed as probable Alzheimer disease.

- The study investigated the side effects of regadenoson, a stress agent for heart imaging, when combined with two types of low-level exercise, focusing on different body mass index (BMI) categories.
- A total of 356 patients participated, undergoing either treadmill walking or sitting leg swings, with results showing differences in side effects based on the type of exercise rather than BMI.
- Treadmill exercise led to fewer side effects like flushing and dizziness compared to sitting exercises, and while heart rate increased more in the treadmill group, blood pressure remained stable across all BMI categories.
