A myocardial perfusion scan assesses the flow of blood to the heart when it's stressed by exercise or medicine. It's performed through injecting thallium into a vein in the arm or hand before the scan.

yes... as long as you dont live across a national border or have to go through airport security to get there... cause you will set off the radiation sensors.

It could be an indication of a blocked coronary artery, however the definitive proof would be a cardiac cath to actually visualize the flow in the vessel and see if it is something that needs to be intervened on.

I googled it and found this: 78480 - Myocardial perfusion study with ejection fraction. It looks like an Add-on code which means there must be a primary procedure code that this is related to.

The medical term VQ scan means a combination of two different tests. These tests are called a ventilation scan and a perfusion scan and a both used for the purpose of testing the health of lungs.

typically in the UK an exercise myocardial test would cost approximately £500. a pharmaceutical (dobutamine or adenosine based ) will cost a fraction bit more.
However cost varies tremendously across the European countries and it will be much cheaper in India for example.

A V-P scan is a ventilation/perfusion scan. Sometimes it's called a V/Q scan as well. It is a radiology study to check how well air is getting into the lungs (ventilation) and how well blood is getting to the lungs (perfusion).

Yes, epinephrine can decrease myocardial oxygen demand by increasing coronary perfusion, improving cardiac output, and reducing systemic vascular resistance. However, high doses of epinephrine may increase myocardial oxygen demand due to its positive inotropic and chronotropic effects.

A thallium heart scan is used to evaluate the blood supply to the heart muscle. It can identify areas of the heart that may have a poor blood supply as a result of damage from a previous heart attack or blocked coronary arteries.

A fixed apical defect on a nuclear medicine myocardial perfusion scan is most likely due to an attenuation artifact caused by breast tissue, diaphragm, or body habitus. This artifact decreases the amount of radiation reaching the camera, resulting in a false defect in the apical region of the heart.

A reversible inferolateral defect seen on a myocardial perfusion imaging scan typically indicates reduced blood flow to the inferior and lateral walls of the heart during stress, but this impairment is reversible with rest. It suggests the presence of ischemia in those regions and may indicate potential underlying coronary artery disease. Follow-up testing and evaluation by a healthcare provider is usually recommended to further assess the significance of this finding.

A pulmonary ventilation/perfusion scan involves two nuclear scan tests. These tests use inhaled and injected radioactive material (radioisotopes) to measure breathing (ventilation) and circulation (perfusion) in all areas of the lungs.
Alternative NamesV/Q scan; Ventilation/perfusion scan; Lung ventilation/perfusion scan
How the test is performedA pulmonary ventilation/perfusion scan is actually two tests. These tests may be performed separately or together.
During the perfusion scan, a health care provider injects radioactive albumin into your vein. You are placed on a movable table that is under the arm of a scanner. The machine scans your lungs as blood flows through them to find the location of the radioactive particles.
During the ventilation scan, you breathe in radioactive gas through a mask while you are sitting or lying on a table under the scanner arm.
How to prepare for the testYou do not need to stop eating (fast), eat a special diet, or take any medications before the test.
A chest x-ray is usually done before or after a ventilation and perfusion scan.
You will sign a consent form and wear a hospital gown or comfortable clothing that does not have metal fasteners.
How the test will feelThe table may feel hard or cold. You may feel a sharp prick while the material is injected into the vein for the perfusion part of the scan.
The mask used during the ventilation scan may make you feel nervous about being in a small space (claustrophobia). You must lie still during the scan.
The radioisotopeinjection usually does not cause discomfort.
Why the test is performedThe ventilation scan is used to see how well air and blood flow moves through the lungs. The perfusion scan measures the blood supply through the lungs.
A ventilation and perfusion scan is most often done to detect a pulmonary embolus(blood clot in the lungs). It is also used to:
- Detect abnormal circulation (shunts) in the blood vessels of the lungs (pulmonary vessels)
- Test lung function in people with advanced pulmonary disease, such as COPD
The health care provider should take a ventilation and perfusion scan and then evaluate it with a chest x-ray. All parts of both lungs should take up the radioisotope evenly.
What abnormal results meanIf the lungs take up lower than normal amounts of radioisotope during a ventilation or perfusion scan, it may be due to:
- Airway obstruction
- Chronic obstructive pulmonary disease (COPD)
- Pneumonia
- Narrowing of the pulmonary artery
- Pneumonitis
- Pulmonary embolus
- Reduced breathing and ventilation ability
Risks are about the same as for x-rays (radiation) and needle pricks.
No radiation is released from the scanner. Instead, it detects radiation and converts it into an image.
There is a small exposure to radiation from the radioisotope. The radioisotopes used during scans are short-lived. All of the radiation leaves the body in a few days. However, as with any radiation exposure, caution is advised for pregnant or breast-feeding women.
There is a slight risk for infection or bleeding at the site where the needle is inserted. The risk with perfusion scan is the same as with inserting an intravenous needle for any other purpose.
In rare cases, a person may develop an allergy to the radioisotope. This may include a serious anaphylactic reaction.
Special considerationsA pulmonary ventilation and perfusion scan may be a lower-risk alternative to pulmonary angiography for evaluating disorders of the lung blood supply.
This test may not provide an definite diagnosis, especially in people with lung disease. Other tests may be needed to confirm or rule out the findings of a pulmonary ventilation and perfusion scan.

Left Ventricular dysfunction-A condition in which the LEFT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE; MYOCARDIAL INFARCTION; and other cardiovascular complications.

Myocardial Infarctions, or heart attacks, can be caused by obesity. A fatty diet or lack of regular exercise can lead to a higher chance of a myocardial infarction.

Myocardial infarction occurs when the blood flow to the myocardium is suddenly reduced or stopped due to constriction or occlusion of coronary arteries leading to myocardial damage.
1 answer
Perfusion is the process through which blood flow is regulated in tissues, delivering oxygen and nutrients while removing waste products. It is essential for maintaining the function and health of organs throughout the body. disruptions in perfusion can lead to tissue damage and organ failure.
