Introduction: Dynamic renal scintigraphy is a useful tool to evaluate kidney function. Software Ostnucline mostly used in the Czech Republic runs however under Windows 98. We had an opportunity to test new software InterViewXP™ from Mediso.

Aim: To compare an operation of both softwares and values of quantitative parameters calculated by both softwares.

Method: We evaluated 34 non-selected patients (13 male, 21 female), average age 53 (21-89) years send to our department for dynamic kidney scintigraphy. Method was performed with a gamma camera MB9200, Tc-99m MAG3 was used as a radiopharmaceutical. Data were processed with both softwares, quantitative parameters were compared with t-test, and level of significance was 5%.

Results: Operation of both softwares is very similar; the main advantage of InterViewXP™ is a possibility to correct for patient motion in two planes. Values of ERPF, separate function and clearance did not differ significantly (p = 0,888-0,999), time intervals differ in the range of minutes (p = 0,304-0,737). All evaluated parameters did not differ significantly.

Conclusion: New software InterViewXP™ for dynamic renal scan provides almost identical values as presently used software Ostnucline. It can, therefore, substitute its use. Its main advantage is a possibility to provide motion correction.
