For the convenience of our users, RadiologyInfo. Prior to imaging, you will be injected with a small amount of radiotracer.

Diuretic renal scintigraphy, ACE-inhibitor renal scintigraphy, renal perfusion and function imaging will typically begin imaging while the tracer is being administered. You will be informed of all significant risks prior to the treatment and have an opportunity to ask questions. The different types of renal scans are used to examine different functional aspects of the kidneys; however, all of these procedures involve the injection of a radiopharmaceutical or radiotracer that emits a tiny amount of radioactivity into the patient.

To locate a medical imaging or radiation oncology provider in your community, you can search the ACR-accredited facilities database. Preparation can vary widely based on the type of scan being conducted. Renal scintigraphy is one of many imaging methods used to evaluate the kidneys.

Renal Scintigraphy

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. Jewelry and other metallic accessories should be left at home if possible, or removed prior to the exam because they may interfere with the procedure. 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.

It is important that you remain still while the images are being recorded.

See the Safety page for more information about pregnancy and breastfeeding related to nuclear medicine imaging. What does the equipment look like? SPECT involves the rotation of the gamma camera heads around the patient’s body to produce more detailed, three-dimensional images.

Women should always inform their physician or technologist if there is any possibility that they are pregnant or if they are breastfeeding. What are some common uses of the procedure? Your doctor will instruct you on how to prepare and may advise you to stop taking some medications or increase fluid intake prior to your exam. You should also inform them if you have any allergies and about recent illnesses or other medical conditions. With ordinary x-ray examinations, an image is made by passing x-rays through the patient’s body.

The gamma camera itself does not emit any radiation. Four types of renal imaging help determine whether the kidneys are working normally or abnormally.

Renal Scintigraphy – Nuclear medicine imaging/scanning of the kidneys

You will receive specific instructions based on the type of scan you are undergoing. You will feel a slight pin prick when the radiotracer is injected.

The camera works with a computer to produce special pictures offering details on both the structure and function of organs and tissues. 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. After the injection, you could gakmagrafia a brief metallic taste. ACE-inhibitor renal scintigraphy helps determine if the cause of a gammmagrafia high blood pressure is coming from the kidneys, due to narrowing of the renal artery or arteries, by comparing kidney images before and after taking a blood pressure medication called an “ACE-inhibitor.

In some cases, the bladder may need to remain empty during the scan, necessitating the insertion of a catheter. Nuclear medicine diagnostic procedures have been used for more than five decades, and there are no known long-term adverse effects from such low-dose exposure. Who interprets the results and how do I get them?

Benefits The information provided by nuclear renal imaging is unique and often unattainable using other imaging procedures. Leave jewelry at home and wear loose, comfortable clothing. In other cases, you may be asked to go to the bathroom and empty your bladder prior to imaging. You will be informed as to how often and when you will need to return to the nuclear medicine department for further procedures. The risks of the treatment are always weighed against the potential benefits for nuclear medicine therapeutic procedures.


Cortical imaging requires a three hour delay after tracer administration for imaging to begin. What is renal scintigraphy? After injection, the radiotracer travels throughout the body to the kidneys, where it gives off gxmmagrafia in the form of gamma rays. If necessary, a nurse or technologist will insert an intravenous IV catheter into a vein in your hand or arm. You may be asked to sit or lie down for the exam. Renal perfusion and functional imaging examines blood gammagrxfia to the kidneys and identifies potential narrowing of the renal arteries.

Renal scintigraphyalso known gammayrafia “renal scans” refers to several examinations using radiopharmaceuticals that evaluate the function and anatomy of the kidneys. You may be asked to wear a gown. Areas of greater intensity, gammagrrafia “hot spots,” indicate where large amounts of the radiotracer have accumulated and where there is a high level of chemical or metabolic activity.

The costs for specific medical imaging tests, treatments and rrnal may vary by geographic region. What are the limitations of renal scintigraphy? The resolution of structures of the body with nuclear medicine may not be as clear as with other imaging techniques, such as CT or MRI. Gammagrafiaa medicine imaging is usually performed on an outpatient basis, but is often performed on hospitalized patients as well. What are the benefits vs.

Your doctor will determine which of these examinations will provide the best information about your kidneys. Photograph of a technologist performing a renal scan on a patient using a gamma camera. Through a series of images taken over 20 to 30 minutes immediately after radiopharmaceutical injection, it also helps determine how well the kidneys are working. What are the limitations of renal imaging?

Nevertheless, you should inform the nuclear medicine personnel of any allergies you may have or other problems that may have occurred during a previous nuclear medicine exam.
