What is a sestamibi scan? A sestamibi (MIBI) scan measures the amount of blood being supplied to your heart. The scan is done in two parts: At rest – sitting and breathing normally. After a chemical or physical stress test – when your heart is beating faster after exercising on a treadmill or exercise bike.

What is a sestamibi scan used for?
A sestamibi scan is used to evaluate the function of the parathyroid glands; these four glands are located in the neck and help manage the body’s calcium levels. To better understand the impact of a sestamibi scan, let’s examine this parathyroid gland assessment in detail.
How is sestamibi administered?
Technetium (99mTc) sestamibi is a lipophilic cation which, when injected intravenously into a patient, distributes in the myocardium proportionally to the myocardial blood flow.
What does sestamibi stand for?
sĕstə-mēbē An injectable drug containing an isotope of the radioactive element technetium, used in nuclear medicine imaging primarily to visualize the heart muscle, parathyroid glands, and breast tissue. noun.
How long does a MIBI scan take?
The final imaging process lasts between 15 and 30 minutes. In a routine exercise stress test, the medication and tracer injections take between 20 and 30 minutes; however, this portion of the exam may take longer. In between, there is a one- to two-hour wait for the tracer to travel to your heart.
How do I prepare for a sestamibi scan?
How do I prepare for a sestamibi scan?
- Avoid caffeine for 24 hours before the test – caffeine may reduce the quality of the scan results (caffeine is in tea, coffee, cola and chocolate.
- Fast (not eat) for 4 hours before the test – but you can drink water.
How accurate are sestamibi scans?
Only the overactive parathyroid gland shows upa very accurate test. The Sestamibi scan will display the hyperactive gland which is causing hyperparathyroidism in about 90 percent (90% sensitivity) of all patients. If the Sestamibi does show the hyperactive gland it is almost always correct (98-100% specificity).
What is the half-life of sestamibi?
Technetium Tc 99m decays by isomeric transition with a physical half-life of 6.02 hours. Blood clearance studies indicate that the fast clearing component clears with a t½ of 4.3 minutes at rest, and clears with a t½ of 1.6 minutes under exercise conditions.
How much does a myocardial perfusion scan cost?
On MDsave, the cost of a Nuclear Stress Test (Myocardial Perfusion Scan) ranges from $990 to $3,173. Those on high deductible health plans or without insurance can save when they buy their procedure upfront through MDsave. Read more about how MDsave works.
What is a NM cardiac myocardial perfusion scan?
A nuclear medicine Myocardial Perfusion (MIBI) exam is used to study the structure and function of the heart. A small amount of radioactive tracer is injected into a vein in your arm and flows proportionally to the heart muscle, showing structure and function of the heart.
What medications should be delayed prior to a sestamibi?
In most cases, you can take your normal medications. However, there are various cardiac (heart) medications which you will need to discontinue (for two days prior to the test), including Isoptin and Beta Blockers (including Inderal, Betaloc, Lopressor, Aptin, Tenormin, Visken).
How much does a sestamibi scan cost?
At a cost of $550 per sestamibi scan and with the error inherent in the scan, it is not cost effective to obtain Tc-99m-sestamibi scan before initial surgery for primary hyperparathyroidism.
How much radiation is in a sestamibi scan?
The mean radiation dose of dynamic parathyroid CT was 5.56 mSv, while sestamibi scintigraphy delivered a mean radiation dose of 3.33 mSv (P <. 05).
What is injected during MIBI?
MIBI is the name given to a radioactive tracer dye that is injected into an arm vein. This dye is safe (see later). It circulates in your circulation, and when it passes through the heart, it is absorbed into HEALTHY HEART MUSCLE CELLS.
Is a MUGA scan the same as an echocardiogram?
But how each test generates images is fundamentally different: A MUGA scan is a nuclear medicine test that uses gamma rays and a chemical tracer to generate images of your heart. An echocardiogram uses high-frequency sound waves and a transducer with a special gel to generate ultrasound images of your heart.
Does a nuclear stress test show blocked arteries?
The test can show the size of the heart’s chambers, how well the heart is pumping blood, and whether the heart has any damaged or dead muscle. Nuclear stress tests can also give doctors information about your arteries and whether they might be narrowed or blocked because of coronary artery disease.
