What is a renal scan/kidney scan?
A renal scan/kidney scan is simply imaging of the kidney. The scan involves using a radioactive substance, which can produce brighter images of the kidneys and the urinary tract when injected into the body. The uses of the test are centred around finding anatomical defects in kidney function or localisation of any cysts. The kidney images are produced with the help of X-rays, CT, or MRI. During the test, you might be asked to stay still as the camera records the internal pictures of your kidneys. The side effects of the test are limited to radioactive exposure.
