What are the other Names for the Procedure?
- Radionuclide Scans
What is Radioisotope Scans radiology procedure? (General Explanation)
- Radioisotope Scans are noninvasive procedures that use very small amounts of radioactive material to diagnose and treat various types of diseases, such as heart disease, cancers, endocrine, gastrointestinal, and neurological problems
- It provides details about the molecular activity in the body and helps detect diseases in their early stages
- A radiotracer can be sent to the organ via injection, swallow, or inhalation of a gas, which eventually goes to the target organ; then, special imaging devices detect the emission and produce pictures
- In image fusion, images are taken using nuclear medicine and superimposed with a CT or MRI scan to produce special images, in order to obtain more information and an accurate diagnosis
What part of the Body does the Procedure involve?
In adults, Radioisotope Scan procedures are used for many organs, such as the heart, thyroid, bones, brain, liver, lung, kidneys, gallbladder, and spleen.
Why is the Radioisotope Scans radiology procedure Performed?
Radioisotope Scans can be used to diagnose the following conditions:
- Gastrointestinal (GI) bleeding
- Blockage in kidney
- Bone cancers
- Urine reflux from the bladder into the kidney
- Abnormality in thyroid glands
What is the Equipment used? (Description of Equipment)
A Radioisotope Scan procedure may use the following tools:
- Positron emission tomography (PET)
- Single photon emission computed tomography (SPECT)
- Gamma camera
- A gamma camera detects radiation and takes pictures from different angles
- The gamma camera is used in SPECT as well, which rotates around the body to produce 3D images of the body
- A computer uses data from the cameras and produces images
What are the Recent Advances in the Procedure?
There have been no recent advances to replace Radioisotope Scan procedures.
What is the Cost of performing the Radioisotope Scans radiology procedure?
The cost of a Radioisotope Scan procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.
In many cases, an estimate may be provided before the procedure. The final amount depends upon the findings during the surgery/procedure and post-operative care that is necessary.
When do you need a Second Opinion, prior to Procedure?
- It is normal for a patient to feel uncomfortable and confused with a sudden inflow of information regarding Radioisotope Scan procedures and what needs to be done
- If the patient needs further reassurance or a second opinion, a physician will almost always assist in recommending another physician.
- Also, if the procedure involves multiple steps or has many alternatives, the patient may take a second opinion to understand and choose the best one. They can also choose to approach another physician independently.

Prior to Radioisotope Scans radiology procedure:
How does the Radioisotope Scans radiology procedure work?
The Radioisotope Scan procedure is outlined:
- The patient is given radioactive material, which accumulates in the target organ
- After the radioactive material has accumulated, a gamma camera, SPECT, or PET scan, detects the radioactivity and takes pictures
- During coronary artery scan, images of blood flow to the heart at rest are taken. After the first scan at rest, the patient is asked to do some exercises for the stress test, or given medications to increase blood flow to the heart
- During exercise, blood flow to the heart increases and thus blockages of coronary arteries are easy to detect. Another scan is performed and it is compared to the scan at rest, to find any blockages
How is the Radioisotope Scans radiology procedure Performed?
The Radioisotope Scan procedure is performed as:
- An intravenous (IV) line is inserted into the patient’s arm
- The radioactive tracer is injected through an IV, or taken orally, inhaled, or injected via a catheter, depending on the nuclear medicine exam
- After the radiotracer injection, the physician waits until the radiotracer accumulates inside the patient’s body. This may take a few hours to a few days
- On the day of imaging, the patient is asked to lie down on a movable imaging table in various positions
- The patient may be asked to hold their breath during the procedure
- The IV line is removed at the end of the procedure
Where is the Procedure Performed?
Radioisotope Scan services are typically provided to both inpatients and outpatients.
Who performs the Procedure?
Radioisotope Scan procedures are performed by nuclear medicine technologists.
How long will the Procedure take?
- The length of time for Radioisotope Scans varies greatly, depending on the type of exam being performed
- The actual scanning time for nuclear imaging exams can take anywhere from 20 minutes to several hours, and may be conducted over several days
Who interprets the Result?
A radiologist, who has specialized training in Radioisotope Scan procedures, interprets the results from the procedure and informs the primary care physician, who then informs the patient.
What preparations are needed, prior to the Procedure?
The following preparations may be needed prior to a Radioisotope Scan procedure:
- The physician may evaluate the individual’s medical history to gain a comprehensive knowledge of the overall health status of the patient, including information related to the medications that are being currently taken
- Do inform the medical professional if you have a history of any medical conditions, such as a heart disease, asthma, diabetes, or kidney disease
- The patient may continue their medications, but if they are taking beta-blocker medications, they should ask the physician about temporary discontinuation of the same
- Do inform the medical professional about any allergies, especially related to barium or iodinated contrast material, which may be used in the procedure
- The individual should not take caffeine and avoid smoking for 48 hours before the procedure
- It is advisable to wear comfortable and loose clothes. Avoid wearing any metal objects or jewelry, as it may interfere with the x-ray
- It is highly recommended to inform your healthcare professional, if you are pregnant or breastfeeding
- The patient must avoid eating or drinking at least 8 hours prior to the procedure, depending on when the procedure is arranged
- Depending on the procedure adopted, the patient may be asked for certain bowel or bladder preparations, before the preparation sessions
What is the Consent Process before the Procedure?
A physician will request your consent for Radioisotope Scan procedures using an Informed Consent Form.
Consent for the Procedure: A “consent” is your approval to undergo a procedure. A consent form is signed after the risks and benefits of the procedure, and alternative treatment options, are discussed. This process is called informed consent.
You must sign the forms only after you are totally satisfied with the answers to your questions. In case of minors and individuals unable to personally give their consent, the individual’s legal guardian or next of kin, shall give their consent for the procedure.
What are the Benefits versus Risks, for this Procedure?
Following are the benefits of Radioisotope Scan procedures:
- It is noninvasive and less expensive procedure and provides detailed information
- It provides details about both structure and function, which is usually unobtainable with other imaging techniques
Following are the risks of Radioisotope Scan procedures:
- Patients may develop an allergic reaction to radioactive material used in the procedure, but it is very rare
- The amount of radioactive material used in the procedure is very small, so the risk from radiation is very minimal compared to other procedures
