What Is Ventilation Perfusion Scan
Radiological test: A ventilation-perfusion (v/q) scan is a specialized radiological lung test comparing mismatches between any part of your lung that still exchanges oxygen (affected in COPD e.g.) and any part that is not receiving blood flow. This is done through radio-tracers. A mismatch means there is a clot in that part of the lung hindering blood flow. Diseases & surgery of the lung complicate interpretation. ...Read moreSee 1 more doctor answer
Let me try to: Myocardial perfusion scan is a nuclear medicine procedure that illustrates the function of the heart muscle (myocardium). It evaluates many heart conditions from coronary artery disease to hypertrophic cardiomyopathy and myocardial wall motion abnormalities. The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction (lvef) of the heart. Good luck. ...Read moreSee 3 more doctor answers
Dx Pulmonary Embolus: A ventillation perfusion lung scan is a nuclear test used to diagnose a blood clot to the lung or pulmonary embolus. Medication is injected into your vein and you also breath a medication into the lung to look for a mismatch on a nuclear imaging camera which would suggest a pulmonary embolus. ...Read moreSee 1 more doctor answer
Lung V-Q scan: Ventilation scanning involves the patient breathing in a radiotracer while perfusion scanning involves injecting the radiotracer through an iv. The procedure is done usually to evaluate the presence of absence of a pulmonary embolism (usually a blood clot) and involves comparing the radiotracer's presence in the alveoli vs. Its presence in the lung circulation. ...Read moreSee 1 more doctor answer
Well...: Since you had a cardiac nuclear scan, I assume your doctors were looking for coronary artery disease. You seem to be a smoker, which makes artery disease worse. So smoking is not a good thing for you, and you should try to stop. Having said that, you are probably not in any more immediate risk for heart problem for smoking after the nuclear exam. Long term risks are greater with smoking. ...Read moreSee 2 more doctor answers
Stress Test: That uses a radioactive tracer to evaluate blood flow in the coronary arteries. Images are taken at peak exercise and at rest . These images are able to compare blood flow to the heart in specific territories supplied by each coronary artery and any flow disparity would be consistent with a potential blockage in that artery. ...Read more
Not realy very: Ventilation/perfusion scan (v/q scan or lung scintigraphy), which shows that some areas of the lung are being ventilated but not perfused with blood (due to obstruction by a clot). This type of examination is used less often because of the more widespread availability of ct technology, however, it may be useful in people who have an allergy to iodinated contrast or in pregnancy. Thanks. ...Read moreSee 1 more doctor answer
Cardiac stress test..: A myocardial perfusion scan is used to detect ischemia or infarction (heart attack) and also to evaluation cardiac function (ejection fraction) and ventricular volumes. If there is significant ischemia sometimes a stent can be placed to prevent infarction. ...Read moreSee 1 more doctor answer
Nuclear stress test: This is a specialized form of stress test used to confirm the presence of coronary artery disease in patients suspected of having this problem. It uses a low-level nuclear tracer to assess blood flow to the heart muscle before and after exercise-induced stress. In patients who cannot exercise, other pharmacologic means can be used such as adenosine, lexiscan, persantine, or dobutamine. ...Read moreSee 2 more doctor answers

VQ scan...: There are 2 parts to a VQ scan: ventilation and perfusion. If there is a clot present, the scan will show that areas of the lung are being ventilated but not perfused. In other words, the clot is preventing blood flow in an area that is being ventilated. This is the classic finding for a pe in a VQ scan but not all scans are that clear-cut so additional testing is sometimes needed. ...Read moreSee 2 more doctor answers
Probably not: A cardiac echo/Doppler study would show pulmonary HTN changes by viewing the right ventricular function , size and pressure. There are additonsl studies that can also be done. It is very important to know WHY you have Pulmonary HTN. If due chronic Pulmonary embolism it is a serious situation for which there exists very effective Rx. Other causes can also be treated. Consult your doc. ...Read more
