Our data show that the addition of limited exercise to dipyridamole results in benefits during Tc-99m sestamibi imaging, increasing heart-to-liver activity ratio, preventing vasodilator-induced hypotension, and improving ECG sensitivity for the detection of ischemia. Furthermore, this protocol also provides an estimation of the patient's physical capacity and could be used as an alternative for patients undergoing dipyridamole infusion who are not completely unable to exercise.

Ga-67 scintigraphy was extremely effective in the differentiation between experimental drug-induced ATN and AIN.

Performing a second and a third cycle in RNC yielded an additional VUR diagnosis of 35.7%, as compared to performing only 1 cycle. The second cycle showed efficacy in all the groups, whereas the third cycle diagnosed more VUR only in group A. These results confirmed the importance of performing additional cycles in RNC for VUR diagnosis, both in children and adults.
