What are the benefits vs. Please type your comment or suggestion into the text box below. You should also inform them if you have any allergies and about recent illnesses or other medical conditions. Renzl 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.
You may be asked to drink extra fluid or possibly receive intravenous IV fluids.

You will be informed of all significant risks prior to the treatment and have an opportunity to ask questions. The camera may rotate around you or it may stay in one position and you will be asked to change positions in between images.
Occasionally, more images are obtained for clarification or better visualization of certain areas or structures. The costs for specific medical imaging tests, treatments and procedures may vary by geographic region.
For the convenience of our users, RadiologyInfo. You should inform your physician and the technologist performing your exam of any medications you are taking, including vitamins and herbal supplements. In other cases, you may be asked to go to the bathroom and empty your bladder prior to imaging. The gamma camera, also called a scintillation camera, detects radioactive energy that is emitted from the patient’s body and converts it into an image.
Depending upon the type of procedure, renal imaging can last from 30 minutes to 2 hours.
Renal cortical scintigraphy detects the amount of functioning renal cortical tissue through images taken with a gamma camera approximately two hours after radiopharmaceutical injection. Photograph of a technologist performing a renal scan on a patient using a gamma camera.
Areas eenal greater intensity, called “hot spots,” indicate where large amounts of the radiotracer have accumulated and where there rena, a high level of chemical or metabolic activity. Cortical imaging requires a three hour delay after tracer administration for imaging to begin.
See the Safety page for more information about pregnancy and breastfeeding related to nuclear medicine imaging. Injection of the radiotracer may cause slight pain and redness which should rapidly resolve.
Please contact your physician with specific medical questions or for a referral to a radiologist or other physician. Send us your feedback Did you find the information you were looking for? Prior to imaging, you will be injected with a small amount of radiotracer.
After injection, the radiotracer travels throughout the body to the kidneys, where it gives off energy in the form of gamma rays. 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.
Nuclear medicine procedures can be time-consuming. You may be asked to wear a gown during the exam or you may be allowed to wear your own clothing. 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.
Four types of renal imaging help determine whether the kidneys are working normally or abnormally. With ordinary x-ray examinations, an image is made by passing x-rays through the patient’s body. The risks of the treatment are always weighed against the potential benefits for nuclear medicine therapeutic procedures.
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. It can provide unique information that is often unattainable using other imaging procedures. While the camera is taking pictures, you will need to remain still for brief periods of time.
Leave jewelry at home and wear loose, comfortable clothing. What will I experience during and after the procedure? What are some common uses of the procedure? In some cases, the camera may move very close to your body. Diuretic renal scintigraphy, ACE-inhibitor renal scintigraphy, renal perfusion and function imaging will typically begin imaging while the tracer is being administered. Renal scintigraphyalso known as “renal scans” refers to several examinations using radiopharmaceuticals that evaluate the function and anatomy of the kidneys.
View full size with caption. 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. What are the limitations of renal scintigraphy? Renal scintigraphy can also be used to evaluate a kidney transplant.
Renal Scintigraphy – Nuclear medicine imaging/scanning of the kidneys
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 functioning normally. 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 a blood pressure medication called an “ACE-inhibitor.
However, nuclear medicine scans are more sensitive than other techniques for a variety of fenal, and the functional information gained from nuclear medicine exams is often unobtainable by any other imaging techniques.
