What is a DTPA scan?
A DTPA (Diethylene-triamine Pentaacetic acid) gives information about
- Any abnormalities in perfusion (blood supply) and drainage of both kidneys
- Possible site of obstruction to the drainage
- Functioning of individual kidney
Similar information can be obtained with MAG-3 and LLEC scans.
How much time will it take to complete a DTPA scan?
Imaging takes 30-60 mins generally. If there is an obstruction to drainage delayed images up to 4 hrs, 6 hrs or more may be needed.
