How does the procedure work? Send us your feedback Did you find the information you were looking for? 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.
Renal cortical scintigraphy detects the amount of functioning renal cortical tissue through images taken with a gamma camera approximately two hours after radiopharmaceutical injection.

In other cases, you may be asked to go to the bathroom and empty your bladder prior to imaging. After injection, the radiotracer travels throughout the body to the kidneys, where it gives off energy in the form of gamma rays.
The costs for specific medical imaging tests, treatments and procedures may vary by geographic region. You should also inform them if you have any allergies and about recent illnesses or other medical conditions.
Injection of the radiotracer may cause slight pain and redness which should rapidly resolve. What are some common uses of the procedure?
You will be positioned on an examination table. 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. SPECT involves the rotation of the gamma camera heads around the patient’s body to produce more detailed, gamagrafia images.
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. 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. Cortical imaging requires a three hour delay after tracer administration for imaging to begin. Leave jewelry at home gammagarfia wear loose, comfortable clothing.
Please type your comment or suggestion into the text box below. Share your patient story renak. You will feel a slight pin prick when the radiotracer is injected. You may be asked to wear a gown. Your doctor will determine which of these examinations will provide the best information about gammagracia kidneys.
What does the equipment look like? Less intense areas, or “cold spots,” indicate a smaller concentration of radiotracer and less chemical 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.
You will be informed as to how often and when you will need to return to the nuclear medicine department for further procedures. gammwgrafia
You also may be asked to discontinue use of some medications prior to your exam. For the convenience of our users, RadiologyInfo. With ordinary x-ray examinations, an image is made by passing x-rays through rwnal patient’s body. Women should always inform their gqmmagrafia or technologist if there is any possibility that they are pregnant or if they are breastfeeding. The special camera and imaging techniques used in nuclear medicine include the gamma camera and single-photon emission-computed tomography SPECT.
This is necessary to obtain the best quality images. This energy is detected by a device called a gamma camera. Renal imaging yields useful information needed to make a diagnosis gammagraffia to determine appropriate treatment, if any.
Allergic reactions to radiopharmaceuticals may occur but are extremely rare and are usually mild. 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. How should I prepare? 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.
Nuclear renal images cannot reliably differentiate between cysts and tumors. While the camera is taking pictures, you will need to remain still for brief periods of time. 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.
Depending upon the type of procedure, renal imaging can last from 30 minutes to 2 hours. 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.
You may be asked to wear a gown during the exam or you may be allowed to gzmmagrafia your own clothing. Renal perfusion and functional imaging examines blood flow to the kidneys and identifies potential narrowing of the renal arteries.
Renal Scintigraphy – Nuclear medicine imaging/scanning of the kidneys
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. What is renal scintigraphy? It is important that you remain still while the images are being recorded. 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.
Diuretic renal scintigraphy, ACE-inhibitor renal scintigraphy, renal perfusion and function imaging will typically begin imaging while the tracer is being administered. 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.
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. The gamma camera itself does not emit any radiation. 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.
It can provide unique information that is often unattainable using other imaging procedures. The camera works with a computer to produce special pictures offering details on both the structure and function of organs and tissues.
