A new approach in radionuclide imaging to ureteric peristalsis using 99Tcm-MAG 3 and condensed images.
A new method for the evaluation of ureteric peristalsis is described. Standard, dynamic renal scintigraphy was carried out using 99Tcm-MAG 3 in 59 patients. Time-activity curves and condensed images over the ureter area were created simultaneously. A six-grade scale (O-V) was chosen for the classification of ureteral function. The results obtained were compared with parameters of renographic curves and other clinical findings. In a group of 13 patients, two different renal radiopharmaceuticals were used: 131I-OIH and 99Tcm-DTPA. The results show that the new method is suitable for the assessment of ureteral disorders, and has some advantages compared with previously described methods. 99Tcm-MAG 3, with a better target-to-background ratio compared to 131I-OIH and 99Tcm-DTPA, is the most suitable radiopharmaceutical for this purpose.
