How Does Caffeine Affect The Results Of Thallium Myocardial Perfusion Scan
Not usually: Caffeine in the usual dietary dose won't affect an exercise stress test with thallium imaging, but if you ingest caffeine recently you cannot have a stress test with pharmacologic stress using Persantine (dipyridamole), Adenosine or Lexiscan because the caffeine interferes with the metabolism of those agents. ...Read moreSee 2 more doctor answers
Cancer risk: It is important to remember that tests commonly done, such as myocardial perfusion scans, ct scans, and plain xrays, expose you to radiation. It adds up. There is an increased incidence of cancer many years later. We cannot practice medicine without those tests but they should only be performed when absolutely necessary. You should question the need for tests involving radiation exposure. ...Read moreSee 2 more doctor answers
Usually not much: Metal can block the gamma rays that are emitted by the patient, and block the xrays from the ct portion of the pet/ct, which can create errors on one portion of the exam (called the attenuation corrected scan). However, the original pet data from the scan (uncorrected) is always available for review, so if the standard images have artifact on them, the uncorrected images can be reviewed. ...Read moreSee 2 more doctor answers
See blood flow: Myocardial perfusion studies show the pattern of blood flow (perfusion) to the tissue of the heart muscle. The radiotracer goes where the blood goes and this shows how well the tissue is nourished. It can be an indicator of blocked arteries when the perfusion pattern is abnormal. ...Read more
Certain medications: Certain medications obscure the ekg changes, or the exercise capacity reducing the utility of the test. Abnormalities of the resting ekg may also impair accuracy. Nuclear scans or echocardiographic images before and after exercise may be performed and may allow a diagnostic test even in these circumstances and also increase the diagnostic accuracy. ...Read more

After taking the Persantine thallium test my dr., informed me of the following; Decreased count rate in the anterior wall; reversible ischemia;; ?
Cannot be sure it is: While decreased count in the anterior wall may be caused by ischemia( inadequate blood flow), there are frequently other causes. In females, decreased anterior wall counts may be an artifact due to the interposition of the breast between the camera and the heart. In true ischemia ,decreased count would be present only in the stress images. Please confirm this with your physician. ...Read more
What does decreased count rates in the anterior septal region with small area of reversibility mean? I had the Thallium test, ekg, and echo tests .
Suggestive of ischem: A small area of anterior septal ischemia of the LV = small area of reduced blood flow at peak stress test. Few things to be mindful: Small refers to area of myocardium in jeapordy; the area mentioned in your case often is place of false + reading; LAST you need to correlate with symptoms if any and your other tests. AND Finally, before seeking therapy if any warranted, ask about COURAGE TRIAl. ...Read more
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
Not much: It means the archetecture and tissue density has changed slightly....because of age and use. But your doctor need to interpret this in the context of your age, blood pressure, other assosiated medical condition Hx, Fhx and urinary finding......last but not the least any previous simmilar test. ...Read more
Father's stress text revealed abnormal myocardial perfusion imaging due to sm area of mild ischemia in the apex. What does this mean?
Test result: If I presume your Dad is the 87y/o person listed on this then the test result has good implications. The gross implication is that there is coronary artery disease present and it isn't producing a lot of ischemia. In an 87y/o without symptoms or minor symptoms, medical therapy is appropriate. ...Read more
Ct scan showed Small vessel Ischemia. Cardioglogist quadruppled beta blocker after EKG. How does the ischemia effect my Kidney disease(stage 4)?
Vessels in both: Without an actual exam, I can't give specific medical advice on your particular health. Same things affect vessels EVERYWHERE. So, while strokes, or heart attacks don't hit the kidney. The same bad vessels are in all organs. Hi BP, diabetes, and cholesterol all clog vessels everywhere and affect all the organs (heart, brain, kidney). Treatable. Or such bad heart disease, no blood gets to kidney. ...Read more

Myocardial perfusion imaging with Tc-99m Sestamibi after exercise
revealed no scintigraphic evidence of hemodynamically significant
ischemia. Medium-sized, mid to basal inferior wall
mild-to-moderate mostly fixed perfusion deficit, excep
Stress test: A stress test with myocardial perfusion imaging is a way of detecting whether the heart muscle is getting insufficient blood supply because of coronary artery disease. It can be normal even with lots of coronary plaque, because it only detects severe narrowings. If there is a "fixed" perfusion defect that generally suggests a scar in the heart muscle from prior heart attack. Need more info. ...Read moreSee 2 more doctor answers
