What is renal scintigraphy? 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.

You may be asked to wear a gown during the exam or you may gammagrafia allowed to wear your own clothing. Nuclear medicine procedures can be time-consuming.

Preparation can vary widely based on the type of scan being conducted. How does the procedure work? 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 also may remal asked to discontinue use of some medications prior to your exam. You should inform your physician and the technologist performing your exam of any medications you are taking, including vitamins and herbal supplements.

Renal imaging yields useful information needed to make a diagnosis or to determine appropriate treatment, if any. Nuclear renal images cannot reliably differentiate between cysts and tumors. You will be informed as to how often and when you will need to return to the nuclear medicine department for further procedures.

ACE-inhibitor renal scintigraphy helps determine if the cause of a patient’s 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 gamkagrafia blood pressure medication called an “ACE-inhibitor. To locate a medical imaging or radiation oncology provider in your community, you can search the ACR-accredited facilities database. Risks Because the doses of radiotracer administered are small, diagnostic nuclear medicine procedures result in relatively low radiation exposure to the patient, acceptable for diagnostic exams.

Renal cortical scintigraphy detects the amount of functioning renal cortical tissue through images taken with a gamma camera approximately two hours after radiopharmaceutical injection. Injection of the radiotracer may cause slight pain and redness which should rapidly resolve.


Nuclear medicine imaging is usually performed on an outpatient basis, but is often performed on hospitalized patients as well. If you are claustrophobic, you should inform the technologist before your exam begins. However, nuclear medicine scans are more sensitive than other techniques for a variety of rena, and the functional information gained from nuclear medicine exams is often unobtainable by any other imaging techniques.

Renal Scintigraphy – Nuclear medicine imaging/scanning of the kidneys

Renal scintigraphy is one of many imaging methods used to evaluate the kidneys. Gmamagrafia The information provided by nuclear renal imaging is unique and often unattainable using other imaging procedures. What are the benefits vs. You may be asked to drink extra fluid or possibly receive intravenous IV fluids. In other cases, you may be asked to go to the bathroom and empty your bladder prior to imaging. Renal perfusion and functional imaging examines blood flow to the kidneys and identifies potential narrowing of the renal arteries.

Renal scintigraphy tammagrafia, also known as “renal scans” refers to several examinations using radiopharmaceuticals that evaluate the function and anatomy of the kidneys. You rensl 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. The risks of the treatment are always weighed gammagraia the potential benefits for nuclear medicine therapeutic procedures. SPECT involves the rotation of the gamma camera heads around the patient’s body to produce more detailed, three-dimensional images. It can provide unique information that is often unattainable using other imaging procedures.

After the injection, you could experience a brief metallic taste. The camera may rotate around you or it may stay in one position and you will gajmagrafia asked to change positions in between images. What are some common uses of the procedure? You may be asked to wear a gown.

The costs for specific medical imaging tests, treatments and procedures may vary by geographic region. Unless your physician tells you otherwise, you may resume your normal activities after your nuclear medicine scan. 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. Depending upon the type of procedure, renal imaging can last from 30 minutes to 2 hours.


This Web page is reviewed regularly by a physician with expertise in the medical area presented and is further reviewed by committees from the Radiological Society of North America RSNA and the American College of Radiology ACRcomprising physicians with expertise in several radiologic areas.

If any special instructions are necessary, you will be informed gammafrafia a technologist, nurse or physician before you leave the nuclear medicine department. What does the equipment look like?

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. Nuclear gammagrafis diagnostic procedures have been used for more than five decades, and there are no known long-term adverse effects from such low-dose exposure.

You will receive specific instructions based on the type of scan you are undergoing. Allergic reactions to radiopharmaceuticals may occur but are renla rare and are usually mild.

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. In some cases, the bladder may need to remain empty during the scan, necessitating the insertion of a catheter.

Web page review process: 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. 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. See the Safety page for more information about pregnancy and breastfeeding related to nuclear medicine imaging. You will be informed of all significant risks prior to the treatment and have an opportunity to ask questions.

Diuretic renal scintigraphy, ACE-inhibitor renal scintigraphy, renal perfusion and function imaging will typically begin imaging while the tracer is being administered.
