Ventilation Perfusion Scan Performed
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
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
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
Pulmonary Embolism: The main reason to perform a pulmonary ventilation-perfusion (v-q) scan is to rule out the presence of a pulmonary embolus (commonly a blood clot). There are several forms of pulmonary thrombo-embolism, but the most common situation is one of sudden onset, leading to sob. Chronic thrombo-embolism leads to development of sob over a long period and it can also be diagnosed with a v-q scan. ...Read moreSee 1 more doctor answer
How many cardiac cta (computed tomography angiogram) procedures are performed annually in small hospitals?
Yes: yes unless they use different medicineGet a more detailed answer ›
Myocardial perfusion Gated SPECT study is positive for medium size fixed perfusion defect involving the adjacent areas of inferior wall and infero- ?
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
Spect images demonstrate inferior and apical reversibility from my nuclear stress test. Is a cardiac catherization must be done?
Not enough data...: Inferior ; apical reversibility means there is some ischemia in those regions. Without seeing the images it is difficult to tell how much. If there is very mild ischemia, some cardiologists may decide to do medical management (only medicines). If there is any significant amount of ischemia, cardiac catheterization is usually done. Again, it depends on the clinical scenario..Not enough data. ...Read moreSee 1 more doctor answer
Not usually: Not usually nuclear medicine affecting ct but the opposite. However ct scan with intravenous iodine contrast materials can affect thyroid scans and thyroid uptake. Renal GFR studies using glofil with i125 are also affected by iodine contrast of ct. ...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
I had nuclear stress study done & interpretation states: Sm reversible ischemia, inferior wall. Ejection fraction 51%. is heart cath needed?
CTA: Cardiac computed tomographic angiograpy is performed to try and diagnose cardiac anatomy and pathology. It doesn't diagnose everything but can provide very useful information that often yield a diagnosis if the study is ordered appropriately. ...Read more
See answer: 2 two types of “cardiac ct exams”. The coronary calcium score is done without iodine contrast and identifies coronary vascular calcifications – which correlate with coronary atherosclerotic disease. The cardiac cta is done with iodine contrast and identifies the coronary vessel lumen allowing more accurate vascular delineation. Your dr. Can advise which is most appropriate for you. ...Read moreSee 1 more doctor answer
