Gammagrafía renal by Jésica Bruno on Prezi

This radioactive material accumulates in the organ or area of your body gammqgrafia examined, where it gives off a small amount of energy in the form of gamma rays. This energy is detected by a device called a gamma camera.

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. You will be positioned on an examination table. You may be asked to wear a gown during the exam or you may be allowed to wear your own clothing.

The camera may rotate around you or it may stay in one position and you will be asked to change positions in between images. The gamma camera itself does not emit any radiation. 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.

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

Who interprets the results and how do I get renaal When it is time gammagraifa the imaging to begin, the gamma camera will take a series of images. In other cases, you may be asked to go to the bathroom and empty your bladder prior to imaging. Renal scintigraphyalso known as “renal scans” refers to several examinations using radiopharmaceuticals that evaluate the function and anatomy of the kidneys. For the convenience of our users, RadiologyInfo. What are the benefits vs. Women should always inform their physician or technologist if there is any possibility that they are pregnant or if they are breastfeeding.

Renal Scintigraphy – Nuclear medicine imaging/scanning of the kidneys

Prior to imaging, you will be injected with a small amount of radiotracer. 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. 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.

It is important that you remain still while the images are being recorded. Cortical imaging requires a three hour delay after tracer administration for imaging to begin. How is the procedure performed? In some cases, the camera may move very close to your body. Please contact your physician with specific medical questions or for a referral to a radiologist or other physician.

Allergic reactions to radiopharmaceuticals may occur but are extremely rare and are usually mild. Diuretic renal scintigraphy, ACE-inhibitor renal scintigraphy, renal perfusion and function imaging will typically begin imaging while the tracer is being administered. See the Gmamagrafia page for more information about pregnancy and breastfeeding related to nuclear medicine imaging. View full size with caption.

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. Occasionally, more images are obtained for clarification or better visualization of certain areas or structures. Renal scintigraphy can also be used to evaluate a kidney transplant. 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.

You may be asked to drink extra fluid or possibly receive intravenous IV fluids. What are the limitations of tammagrafia imaging? Renal imaging yields useful information needed to make a diagnosis or to determine appropriate treatment, if any.

Preparation can vary widely based on the type of scan being conducted. 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 also be given a diuretic to increase urine production. 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 does the equipment look like? Less intense areas, or “cold spots,” indicate a smaller concentration of radiotracer and less chemical activity.

When the examination is completed, you may be asked to wait until the technologist checks the images in case additional images are needed. This is necessary to obtain the best quality images. Nuclear medicine procedures can be time-consuming. If any special instructions are necessary, you will be informed by a technologist, nurse or physician before you leave the nuclear medicine department.

Sometimes, the gamma camera heads are oriented at a 90 degree angle and placed over the patient’s body. Jewelry and other metallic accessories should be left at home if possible, or removed prior to the exam because they may interfere with the procedure. Renal cortical scintigraphy detects the amount of functioning renal cortical tissue through images taken with a gamma camera approximately two hours after radiopharmaceutical injection.

What are the limitations of renal scintigraphy? Benefits The information provided by nuclear renal imaging is unique and often unattainable using other imaging procedures.

While the camera is taking pictures, you will need to remain still for brief periods of time. If you are claustrophobic, you should inform the technologist before your exam begins. What are some common uses of the procedure?
