This website does not provide cost information. Occasionally, more images are obtained for clarification or better visualization of certain areas or structures. How should I prepare? Gammagrafa a series of images taken over 20 to 30 minutes immediately after radiopharmaceutical injection, it also helps determine how well the kidneys are working. The camera may rotate around you or it may stay in one position and you will be asked to change positions in between images.

You will receive specific instructions based on the type of scan you are undergoing. Leave jewelry at home and wear loose, comfortable clothing.

Allergic reactions to radiopharmaceuticals may occur but are extremely rare and are usually mild. Renal scintigraphy is one of many imaging methods used to evaluate the kidneys. This radioactive material accumulates in the organ or area of your body being gaammagrafia, where it gives off a small amount of energy in the form of gamma rays.

While the camera is taking pictures, you will need to remain still for brief periods of time. When the examination is completed, you may be asked to wait until the technologist checks the images in case additional images are needed. 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.

After the injection, you could experience a brief metallic taste. The gamma camera itself does not emit any radiation.

Ga,magrafia medicine imaging is usually performed on gammagrafai outpatient basis, but is often performed on hospitalized patients as well. 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.

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.

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. For the convenience of our users, RadiologyInfo.

Renal Scintigraphy

What are some common uses of the procedure? You should inform your physician and the technologist performing your exam of any medications you are taking, including vitamins and herbal supplements. Please type your comment or suggestion into the text box below. This energy is detected by a device called a gamma camera. Nuclear renal images cannot reliably differentiate between cysts and tumors. Unless your physician tells you otherwise, you may resume your normal activities after your nuclear medicine scan.

You may be asked to drink extra fluid or possibly receive intravenous IV fluids. You may be asked to wear a gown. You may rsnal be given a diuretic to increase urine production.

Renal Scintigraphy – Nuclear medicine imaging/scanning of the kidneys

Four types of renal imaging help determine whether the kidneys are working normally or abnormally. This is necessary to obtain the best quality images. After injection, the radiotracer travels throughout the body to the kidneys, where it gives off energy in the form of gamma rays.


Please contact your physician with specific medical questions or for a referral to a radiologist or other physician. Renal cortical scintigraphy detects the amount of functioning renal cortical tissue through images taken with a gamma camera approximately two hours after radiopharmaceutical injection.

You rena be informed as to how often and when you will need to return to the nuclear medicine department for further procedures. Because the radiotracer interacts differently in different kinds of tissue, it can help physicians determine if something is wrong with the kidneys or if the kidneys are gajmagrafia normally. 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.

You should also inform them gammwgrafia you have any allergies and about recent illnesses or other medical conditions. It can provide unique information that is often unattainable using other imaging procedures. If you are claustrophobic, you should inform the technologist before your exam begins. Renal scintigraphy can also be used to evaluate a kidney transplant. In some cases, the camera may move very close to your body.

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

You may be asked to wear a gown during the exam or you may be allowed to wear your own clothing.
