Kidney Imaging (Renal Scan)

What is Kidney or Renal Imaging?

Renal Scans allow the physician to monitor the flow or urine, the degree of any blockage and access the amount of scarring in the kidney tissue.

What takes place during the test?

A small needle or IV will be placed in the arm where it will remain for most of the test. You will then be injected through the IV with a radionuclide material and scanned for approximately 40 minutes. During the scan, you will lie on the imaging table with the camera positioned above or below you while several images are taken. Also during the scan, you will be given a diuretic through the IV to speed up flow through the urinary tract. Pediatric exams require catheter insertion from the beginning of the test until completion to help keep the bladder empty and decrease chance of urinary back-up.

How long will the test take to complete?

Approximately 45 minutes.
