Objective: To validate an IDL program for processing dynamic renal scans written by one of our physicists and if successful validation occurred implement its use amongst technologists. Our department had 17 technologists at the time of this study so it was also a good chance to analyse their individual processing of dynamic renal scans.

Method: For validation of the IDL program 20 renal scans were chosen. These included a range of normal and abnormal scans (including duplex kidneys and single kidneys). These scans were processed by 2 technologists. They were processed once using the current system by both technologists separately and were processed again by both technologists separately using the new IDL program. Left and right differential function was recorded as well as left and right half clearance times. For implementation of the IDL program and to check technologists' processing, technologists were given a lesson in how to use the new IDL program. 5 of the original scans used for validation were chosen and each technologist processed them using the IDL program.

Results: These will be discussed in more detail on the poster (graphs and images included) but the validation was successful and our consultants were happy to start using the program clinically. All technologists could use the program successfully but there were some inconsistencies in processing.

Conclusion: The validation of the specially written IDL program was successful. All technologists could use the program successfully but care and thought needs to be used when processing dynamic renal scans.
