Renal Scan (Renogram)

What is a Renogram?

A renogram is a nuclear medicine study performed to evaluate kidney function.

What should I do to prepare for my exam?

Empty your bladder before the study begins.

What will happen during a renogram and how will I get my results?

The patient will lie on a table with the gamma camera over the abdomen. The patient will be injected, intravenously, with a small amount of radioactive tracer. Images begin immediately. This test takes 30 minutes. A second injection may be given around 12 minutes into the study. A post study image over the bladder will be taken.

The physician who interprets the scan will send a report to your physician, who will then share the results with you.
