SPECT involves the rotation of the gamma camera heads around the patient’s body to produce more detailed, three-dimensional images. What are the limitations of renal scintigraphy? Preparation can vary widely based on the type of scan being conducted. If you are claustrophobic, you should inform the technologist before your exam begins. Renal perfusion and functional imaging examines blood flow to the kidneys and identifies potential narrowing of the renal arteries.
Renal scintigraphy can also be used to evaluate a kidney transplant. Renal scintigraphy is one of many imaging methods used to evaluate the kidneys.
In other cases, you may be asked to go to the bathroom and empty your bladder prior to imaging. Please type your comment or suggestion into the text box below.
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.
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.
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. The camera works with a computer to produce special pictures offering details on both the structure and function of organs and tissues.
Renal Scintigraphy – Nuclear medicine imaging/scanning of the kidneys
A radiologist or other physician who has specialized training in nuclear medicine will interpret the images and send a report to your referring physician.
Who interprets the results and how do I get them? Your doctor will determine which of these examinations will provide the best information about your kidneys. 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.
You will be positioned on an examination table. With ordinary x-ray examinations, an image is made by passing x-rays through the patient’s body. 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. What are the benefits vs.
Diuretic renal scintigraphy, ACE-inhibitor renal scintigraphy, renal perfusion and function imaging will typically begin imaging while the tracer is being administered.
After the injection, you could experience a brief metallic taste. View full size with caption. Four types of renal imaging help determine whether the kidneys are working normally or abnormally. 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. You will be asked to lie on your back or sit gxmmagrafia, and will need gammagrfia remain as still as possible while the camera takes each picture.
Renal imaging yields useful information needed to make a diagnosis or to determine appropriate treatment, if any. 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. Prior to imaging, you will be injected with a small fenal of radiotracer. While the camera is taking gsmmagrafia, you will need to remain still for brief periods of time. The costs for gammagrxfia medical imaging tests, treatments and procedures may vary by geographic region.
You will be informed as to how often and when you will need to return to the nuclear medicine department for further procedures. 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.
The gamma camera itself does not emit any radiation. Send us your feedback Did you find the information you were looking for?
Share your patient story here. 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.
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. This website gmmagrafia not provide cost information.
Nuclear medicine imaging is usually performed on an outpatient basis, but is often performed on hospitalized patients as well. You will be informed of all significant risks prior to the treatment and have an opportunity to ask questions.
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.
When it is time for the imaging to begin, the gamma camera will take a series of images. Less intense areas, or “cold spots,” indicate a smaller concentration of radiotracer and less chemical activity.
