Nuclear medicine imaging is usually performed on an outpatient basis, but is often performed on hospitalized patients as well. Diuretic renal scintigraphy, ACE-inhibitor renal scintigraphy, renal perfusion and function imaging will typically begin imaging while the tracer is being administered.

Nevertheless, you should inform the nuclear medicine personnel of any allergies you may have or other gammaagrafia that may have occurred during a previous nuclear medicine exam. What is renal scintigraphy? 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.
While the camera is taking pictures, you will need to remain still for brief periods of time. You will be informed as to how often and when you will need to return to the nuclear medicine department for further procedures. This radioactive material accumulates in the organ or area of your body being examined, where it gives off a small amount of energy in the form of gamma rays.
This website does not provide cost information. Four types of renal imaging help determine whether the kidneys are working normally or abnormally.

Injection of the radiotracer may cause slight pain and redness which should rapidly resolve. What are the benefits vs. If you are claustrophobic, you should inform the technologist before your exam begins. You should also inform them if you have any allergies and about recent renaal or other medical conditions. Renal cortical scintigraphy detects the amount of functioning renal cortical tissue through images taken with a gamma camera approximately two hours after radiopharmaceutical injection.
If necessary, a nurse or technologist will insert an intravenous IV catheter into a vein in your hand or arm. Preparation can vary widely based on the type of scan being conducted.
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.
Cortical imaging requires a three hour delay after tracer administration for imaging tenal begin. Renal perfusion and gammwgrafia imaging examines blood flow to the kidneys and identifies potential narrowing of the gammagracia arteries.

How does the procedure work? The camera may rotate around you or it may stay in one position and you will be asked to change positions in between images. Nuclear renal images cannot reliably differentiate between cysts and tumors.
What will I experience during and after the procedure? Renal scintigraphyalso known as “renal scans” refers to several examinations using radiopharmaceuticals that evaluate the function and anatomy of the kidneys. 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. However, nuclear medicine scans are more sensitive than other techniques for a variety of indications, and the functional information gained from nuclear medicine exams is often unobtainable by any other imaging techniques.
Women should always inform their physician or technologist if there is any possibility that they are pregnant or if they are breastfeeding. 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. Share your patient story here. 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 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.
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.
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. SPECT involves the rotation of the gamma camera heads around the patient’s body to produce more detailed, three-dimensional images. The costs for specific medical imaging tests, treatments and procedures may vary by geographic region.
You may also be given a diuretic to increase urine production. It can provide unique information that is often unattainable using other imaging procedures. Renal scintigraphy can also be used to evaluate a kidney transplant. Renal scintigraphy is one of many imaging methods used to evaluate the kidneys. What does the equipment look like? A radiologist or other physician who has specialized training in nuclear medicine will interpret the images and send a report to your referring physician.
Please type your comment or suggestion into the text box below. 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.
Web page review process: The gamma camera, also called a scintillation camera, detects radioactive energy that is vammagrafia from the patient’s body and converts it into an image.
This is necessary to obtain the best quality images. Who interprets the results and how do I get them?
It is gammagraria that you remain still while the images are being recorded. In some cases, the camera may move very close to your body. To locate a medical imaging or radiation oncology provider in your community, you can search the ACR-accredited facilities database.
When it is time for the imaging to begin, the gamma camera will take a series of images.
