Send us your feedback Did you find the information you were looking for? You should inform your physician and the technologist performing your exam of any medications you are taking, including vitamins and herbal supplements. With ordinary x-ray examinations, an image is made by passing x-rays through the patient’s body.

How is the procedure performed? Cortical imaging requires a three hour delay after tracer administration for imaging to begin.

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 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.

Nuclear medicine imaging is usually performed on an outpatient basis, but is often performed on hospitalized patients as well.

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. The risks of the treatment are always weighed against the potential benefits for nuclear medicine therapeutic procedures.


The different types of renal scans are used to examine different functional aspects of the kidneys; however, all gmamagrafia these procedures involve the injection of a radiopharmaceutical or radiotracer that emits a tiny gammagarfia of radioactivity into the patient.

This energy is detected by a device called a gamma camera. In some cases, the bladder may need to remain empty during the scan, necessitating the insertion of a catheter. Sometimes, the gamma camera heads are oriented at a 90 degree angle and placed over the patient’s body.

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. Gammagrzfia can vary widely based on the type of scan being conducted.

When the examination is completed, you may be asked to wait until the technologist checks the images in case additional images are needed. Diuretic renal scintigraphy, ACE-inhibitor renal scintigraphy, renal perfusion and function imaging will typically begin imaging while the tracer is being administered. If any special instructions are necessary, you will be informed by a gsmmagrafia, nurse or physician before you leave the nuclear medicine department.

Please type your comment or suggestion into the text box below. Prior to imaging, you will be injected with a small amount of radiotracer. The special camera and imaging techniques used in nuclear medicine include the gamma camera and single-photon emission-computed tomography SPECT. 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. If necessary, a nurse or technologist will insert an intravenous IV catheter into a vein in your hand or arm.


If you are claustrophobic, you should inform the technologist before your exam begins. 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.

Renal Scintigraphy – Nuclear medicine imaging/scanning of the kidneys

Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown. Renal cortical scintigraphy detects the amount of functioning renal cortical tissue through images taken with a gamma camera approximately two hours after radiopharmaceutical injection. You may be asked to wear a gown during the exam or you may be allowed to wear your own clothing.

Share your patient story here. You also may be asked to discontinue use of some medications prior to your exam. 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 rsnal.

What does the equipment look like? You may be asked to sit or lie down for the exam. You should also inform them if you have any allergies and about recent illnesses or other medical conditions.

In some cases, the camera may move very close to your body. What are the limitations of renal imaging?
