If you are claustrophobic, you should inform the technologist before your exam begins. What are the limitations of renal imaging?

Allergic reactions to radiopharmaceuticals may occur but are extremely rare and are usually mild. 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.

Thus, the radiation risk is very low compared with the potential benefits. However, nuclear renxl scans are more sensitive than other techniques for a variety of indications, and the functional eenal gained from nuclear medicine exams is often unobtainable by any other imaging techniques.

View full size with caption. The camera works with a computer to produce special pictures offering details on both the structure and function of organs and tissues. 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. You may be asked to sit or lie down for the exam.

Four types of renal imaging help determine whether the kidneys are working normally or abnormally. What are the benefits vs. This energy is detected by a device called a gamma camera. For the convenience reanl our users, RadiologyInfo.

You also may be asked to discontinue use of some medications prior to your exam. 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. SPECT involves the rotation of the gamma camera heads around the patient’s body to produce more detailed, three-dimensional images. See the Safety page for more information gammagrafka pregnancy and breastfeeding related to nuclear medicine imaging.

The special camera and imaging techniques used in nuclear medicine include the gamma camera and single-photon emission-computed tomography SPECT. Women should always inform their physician or technologist if there is any possibility that they are pregnant or if they are breastfeeding.

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. To locate a medical gammagratia or radiation oncology provider in your community, you can search the ACR-accredited facilities database.

Renal scintigraphy is one of many imaging methods used to evaluate the kidneys. Sometimes, the gamma camera heads are oriented at a 90 gammaggafia angle and placed over the patient’s body.

Risks Because the doses of radiotracer gammatrafia are small, diagnostic nuclear medicine procedures result in relatively low radiation exposure to the patient, acceptable for diagnostic exams. Areas of greater intensity, called “hot spots,” indicate where large rennal of the radiotracer have accumulated and where there is a high level of chemical or metabolic activity.

After injection, the radiotracer travels throughout the body to the kidneys, where it gives off energy in the form of gamma rays. Leave jewelry at home and wear loose, comfortable clothing. If any special instructions are necessary, you will be informed by a technologist, nurse or physician before you leave the nuclear medicine department.

Renal Scintigraphy – Nuclear medicine imaging/scanning of the kidneys

The risks of the treatment are always weighed against the potential benefits for nuclear medicine therapeutic procedures. 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. You will be informed of all significant risks prior to the treatment and have an opportunity to ask questions. You will be gammafrafia on an examination table.

In other cases, gam,agrafia may be asked to go to the bathroom and empty your bladder prior to imaging. What will I experience during and after the procedure?

Renal Scintigraphy

Preparation can vary widely based on the type of scan being conducted. With ordinary x-ray examinations, an image is made by passing x-rays through the patient’s body. Renal perfusion and functional imaging examines blood flow to the kidneys and identifies potential narrowing of the renal arteries.

You may be asked to wear a gown. Web page review process: The gamma camera itself does not emit any radiation. Cortical imaging requires a three hour delay after tracer administration for imaging to begin.
