What Are The Side Effects Of Lung Perfusion Scan
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
Inject radioactive: A perfusion lung scan is done by injectecting a low-dose radioactive tracer into a vein and taking images showing where blood flow is going in the lungs. It is used to diagnose pulmonary embolism (blood clot to the lungs). The test is safe and generally free of any side effects. It is used less often now than ct angiogram, but is safer and involves less radiation exposure. ...Read moreSee 1 more doctor answer
None: There are no common side-effects from the radioisotope. There have been very rare reports of allergy. There is a theoretical, but unproven risk of the radiation inducing a cancer 10 to 20 years later. There also is a theoretical, but unproven risk of radiation myocarditis. The radiation exposure of 1 rem (about 10 msv ) has not been shown to be harmful. See http://sgoti.Ws/qmhwh7. ...Read moreSee 1 more doctor answer
Have chest tightness in cold air or with anxiety. Ekg, blood tests, echocardio and myocardial perfusion scan (cardio) are normal. What could it be?
Dr order pulm. Ventilation/perfusion scan for tachardyia and sob. Have normal chest x-ray, ekg, pulmonary test and blood work. Odds it's an embolism?
Odds don't count: Stastitics are only guidelines and don't apply to individual cases. A lung scan (v/q) is accurate if it is considered high probability or normal. The " gold standard" is computerized angiogram of the chest which is very accurate both to diagnose or exclude pulmonary embolism. Talk to your md. If you have no medical contraindications, i would prefer the ct angiogram. ...Read moreSee 1 more doctor answer
