dipyridamole thallium 201 scan

ECG last month showed SVES, RBBB. This week he has stress test with dipyridamole protocol, and injection of thallium-201. The result showed "evidence of mild, small to medium size, irreversible perfusion defect in the inferior/inferolateral wall (mid to basal level)." Could you explain what this means? Does he need to have surgery or pacemaker? thanks in advance for your help.

Thallium stress tests utilize thallium-201, with a physical half-life of about three days. This means that the activity or emissions from a vial of thallium-201 will decrease by half every three days. Thus, after three days, the activity will be one-half of the initial activity. After six days it will be about one-fourth of the initial activity, and so forth.

thallium stress test Report.. Please Tell me the conclusion of Report ? do I need angiography ? Dipyridamole myoview spect myocardial perfusion study Age / Sex : 65/M Indication: HTN, DM, ? IHD Isotope : 7mCi of Tc-99m Myoview at peak stress 21mCi of Tc-99m Myoview at rest Persantin Infusion Stress: Pharmacological Intervention was performed with injection persantin (Dipyridamole) at a rate of 0.142 mg/kg/min, 07 Mci of Tc-99m Myoview was given I/V. His resting ECG showed 0.

It is seen occasionally during re-injection phase of thallium-201 It has a complex and somewhat controversial explanation, but essentially there is an imbalance between thallium entering the heart tissue (dependent on blood flow) and leaving it (dependent on muscle cell health). What RR actually represents depends on why the patient got the test (fresh heart attack? old heart attack? unknown reason for chest pain?

Hello: In my opinion I don't think it is appropriate to evaluate or base risk of these radionuclide based on data extrapolated from external sources of radiation. And l really don't think the risk from a single Thallium scan to be minimal; instead it is very significant. The risk from this radionuclide comes in two forms: one the radiation they emit and second by the process they decay (i.e. Auger decay is highly mutagenic). This is specially true in the case of Thallium 201.

The substance used in a nuclear scan is injected and is usually Thallium. You can google THALLIUM and see what you think. Your Doctor has an interest in cardiology but I can't understand why he has chosen a nuclear perfusion scan at this stage? I had two blocked arteries and a nuclear scan said I was absolutely fine. My Cardiologist said "it's only really good for one thing, to see if there are any areas of dead muscle, apart from that, it's next to useless".

I've had two nuclear stress tests in the last four years. The first one was done with technetium 99 which i've read gives you 500 msv of radiation and has a half life of 6 hours, but the second one was done with 3.0mci of thallium 201 and 22mci of myoview after stress.

The thallium scan helps determine if areas of the heart do not receive enough blood. The exercise thallium scan is especially useful in diagnosing coronary artery disease, the presence of blockages in the coronary arteries (the vessels that supply oxygen-rich blood to the heart muscle). Yes, it would be appropriate to take a stress test to determine if there are any vessel occlusions that may be blocking a good and adequate blood supply to the heart cells.

There are many names for this same thing. Nuclear perfusion test, nuclear stress test, thallium stress test, thallium scan etc etc. Maybe they should standardise on the name to make it less confusing.

Now this is the complete history i want to ask that such kind of reports comes for how much time or period Thallium scan is effective My age is 34 years old and one important thing such chest discomfort is not related with Physical activity of exertion and Blood pressure also remains the same.

A classic example could be a patient with strong Angina who has a Thallium scan, which shows good results. This means (in most cases) collateral vessels have opened to feed past the blockage. An Angiogram will not see tiny vessels. So the Thallium shows although there's angina, it isn't really life threatening. What it does say is that there isn't enough blood flow through those collaterals to prevent angina, but certainly enough to keep the muscle alive.

ve probably had one of these before the thallium scan anyway.

that did not impact my thallium test. The only possible conflicts could be if injecting you with the thallium isotope was a problem, or your overall health made doing stressful physical exercise risky. But if you don't have any of those problems you should be good to go. It's a workout, but have fun!!

I had a stress thallium done and got the report today. It shows 2mm ST depression inferolateral leads-abnormal. Myocardial profusion scan normal, no wall motion abnormalities. I am a 37 yr old female, overweight with a strong family history of early heart disease. It was a chemical stress thallium and they wouldn't let me walk on the treadmill instead.

I recently had a Thallium stress test which came back positive. The sets of images were taken by two different techs while I sat upright in a chair. Not wanting to believe the worst, I went to another Cardiologist. There I had the Cardiolite test, images taken by the same tech while I lay on a table. Those results came back negative. So who is right? Would having a calcium-score CT and perhaps a carotid ultrasound be the tie-breaker? I am 55 years old, post menopausal.

I was booked for a thallium test. I went to see my cardiologist after the thallium scan, thinking I was going to be told half my heart was dead or something, but I was shocked, as was the cardiologist, to learn none was dead. The cardiologist said that the thallium revealed excellent blood supply to all areas of the heart, and yet I was still suffering bad angina on any exertion.

The pictures from the thallium scan showed nothing. He is scheduled for an angiogram and we wonder if this is truly necessary. The only other anomaly he has is that his heart rate is consistently low, getting into the low 50's at rest. He takes no medicine of any kind and does not drink. What could cause the difference between low heart rate, abnormal EKG and the thallium pictures other than a blockage, that is somehow not seen on the scan? thanks for any advice.

Had a growth scan at.31+2 and bub is 5lb already. Got to have another scan at 36 to monitor her size. Anyone had this experience? Wot options are given for a big baby? This is my first and am worried.

Hi Linda, a Thallium scan involves having a dye injected into your circulatory system when you are exercising on a treadmill. If unable to do this, your heart rate will be increased using medication. Stress is a strange word really I think, it simply refers to your heart working harder, at the optimum for your age etc. Hardly stress in the sense of the word is it. Anyway, you have one scan with the heart having been stressed and they take 20-30 mins lying still.

The adverse effects experienced are similar to those with use of adenosine. While adverse effects are less frequent with dipyridamole (47% of patients), they tend to be more serious than those associated with adenosine. The most common adverse effects of dipyridamole are chest pain (19%), headache (12%), and hypotension (4.6%). In addition, 12% of patients require aminophylline for reversal of adverse effects.

Pharmacological stress Tc-99m MIBI scan was performed with Dipyridamole given at arate of 0.14 mg/Kg/min over 4 minutes followed by injection of radio tracer 6 minutes later. Findings are: Peak stress images revealed hypoperfused infero-septal and apical segment, which showed reversal at rest. Impression: Findings are consistent with infero-septal and apical reversible ischemia. Thanks all!
