It is important that you remain still while the images are being recorded. You will be informed as to how often and when you will need to return to the nuclear medicine department for further procedures. Nuclear renal images cannot reliably differentiate between cysts and tumors. Less intense areas, or “cold spots,” indicate a smaller concentration of radiotracer and less chemical activity.

Please contact your physician with specific medical questions or for a referral to a radiologist or other physician. Occasionally, more images are obtained for clarification or better visualization of certain areas or structures. This energy is detected by a gammagrafi called a gamma camera.

A radiologist or other physician who has specialized training in nuclear medicine will interpret the images and send a report to your referring physician.

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. What is renal scintigraphy?

Renal scintigraphy is one of many imaging methods used to evaluate the kidneys. Unlike other imaging techniques, nuclear medicine imaging exams focus on depicting physiologic processes within the body, such as rates of metabolism or levels of various other chemical activity, instead of showing anatomy and structure.

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.

What are some common uses of the procedure? With ordinary x-ray examinations, an image is made by passing x-rays through the patient’s body.

Renal Scintigraphy

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. While the camera is taking pictures, you will need to remain still for brief periods of time.

What will I experience during and after the procedure? Renal perfusion and functional imaging examines blood flow to the kidneys and identifies potential narrowing of the renal arteries. You should inform your physician and the technologist performing your exam of any medications you are taking, including vitamins and herbal supplements.

Sometimes, the gamma camera heads are oriented at a 90 degree angle and placed over the patient’s body. Web page review process: 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. Four types of renal imaging help determine whether the kidneys are rehal normally or gammagratia. You may be asked to wear a gown during the exam or you may be allowed to wear your own clothing.

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. Who interprets the results and how do I get them?

If any special instructions are necessary, you will be informed by a technologist, nurse or physician before you leave the nuclear medicine department. 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.

You may also be given a diuretic to increase urine production. You may be asked to drink extra fluid or possibly receive intravenous IV fluids. Renal cortical scintigraphy detects the amount of functioning renal cortical tissue through images taken with a gamma camera approximately two hours after radiopharmaceutical injection. The camera may rotate around you or it may stay in one position and you will be asked to change positions in between images.

You will feel a slight pin prick when gammagrafiia radiotracer is injected.

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.

You will receive specific instructions based on the type of gammmagrafia you are undergoing. After the injection, you could experience a brief metallic taste.

Renal Scintigraphy – Nuclear medicine imaging/scanning of the kidneys

In some cases, the camera may move very close to your body. Your doctor will determine which of these examinations will provide the best information about your kidneys. The risks of the treatment are always weighed against the potential benefits for nuclear medicine therapeutic procedures.

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. Women should always inform gamagrafia physician or technologist if there is any possibility that they are pregnant or if they are breastfeeding.

For the convenience of our users, RadiologyInfo. Thus, the radiation risk is very low compared with the potential renaal.
