You will receive specific instructions based on the type of scan you are undergoing. Renal scintigraphy can also be used to evaluate a kidney transplant. Renal scintigraphy is one of many imaging methods used to evaluate the kidneys.

You will be asked to lie on your back or sit up, and will need to remain as still as possible while the camera takes each picture. The gamma camera is composed of radiation detectors, called gamma camera heads, which are encased in metal and plastic and most often shaped like a box, attached to a round circular donut shaped gantry.

You will be positioned on an examination table. If any special instructions are necessary, you will be informed by gmamagrafia technologist, nurse or physician before you leave the nuclear medicine department.

Cortical imaging requires a three hour delay after tracer administration for imaging to begin.

Renal Scintigraphy

Injection of the radiotracer may cause slight pain and redness which should rapidly resolve. You will be informed as to how often and when you will need to return to the nuclear medicine department for further procedures.

Nuclear renal images cannot reliably differentiate between cysts and tumors.


Areas of greater intensity, called “hot spots,” indicate where large amounts of the radiotracer have accumulated and where there is a high level of chemical or metabolic activity. You may be asked to wear a gown. You may also be gammmagrafia a diuretic to increase urine production. If you are claustrophobic, you should inform the technologist before your exam begins. What are some common uses of the procedure?

Renal Scintigraphy – Nuclear medicine imaging/scanning of the kidneys

What does the equipment look like? Though nuclear imaging itself causes no pain, there may be some discomfort from having to remain still or to stay in one particular position during imaging. You may be asked to drink extra fluid or possibly receive intravenous IV fluids. In some cases, the bladder may need to remain empty during the scan, necessitating the insertion of a catheter.

Four types of renal imaging help determine whether the kidneys are working normally or abnormally. Nuclear medicine procedures can be time-consuming. SPECT involves the rotation of the gamma camera heads around the patient’s body to produce more detailed, three-dimensional images. Please type your comment or suggestion into the text box below. The patient lies on the examination table which slides in between two parallel gamma camera heads that are positioned above the patient and beneath the examination table.

This energy is detected by a device called a gamma camera. When it is time for the imaging to begin, the gamma camera will take a series of images. You may be asked to wear a gown during the exam or you may be allowed to wear your own clothing.

See the Safety page for more information about pregnancy and breastfeeding related to gammagrqfia medicine imaging. The need for additional images does not necessarily mean there was a problem with the exam or that something abnormal was found, and should not be a cause of concern for you.


You should also inform them if you have any allergies and about recent illnesses or other medical conditions. How is the procedure performed? The gamma camera itself does not emit any radiation. Send us your feedback Did you find the information you were looking for? It is important that you remain still while the images are being recorded. In contrast, nuclear medicine procedures use a radioactive material, called a radiopharmaceutical or radiotracer, which is injected into the bloodstream, swallowed or inhaled as a gas.

Diuretic renal scintigraphy detects kidney blockages or obstruction of urine flow through images taken before and after the introduction of a diuretic to move urine through the kidneys. Unlike other imaging techniques, nuclear medicine imaging exams focus on depicting physiologic processes within the body, such as rates of metabolism or levels of various other chemical activity, instead of showing anatomy and structure.

Depending upon the type of procedure, renal imaging can last from 30 minutes to 2 hours. Special cameras detect this energy, and with the help of a computer, create pictures offering details on both the structure and function of organs and tissues in your body.
