Hi
The test you've just had is called a nuclear perfusion scan and it basically involved putting a radioactive contrast into your blood stream which will find its way into your cells. This contrast is called Thallium and the ideology being, if there is no thallium in a group of cells, then they are going to be dead. This is because they have been without a blood supply for too long, the vessel supplying those cells is blocked. The thallium doesn't stay in your body very long after.
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!
I had a false positive on my nuclear stress test. when I did my angiogram the nurse said up to 50% of nuclear stress tests are false positive. Great technology !
I just had a nuclear scan and stress test of the heart. The nuclear scan showed a hypokinetic med anterior wall. My ejection fraction is 67%. Does this suggest a prior heart attack, and, if so, how concerned should I be? My good and bad cholesterol is low. I have type II diabetes. I also had an echocardiogram recently that was normal.
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.
...16 x 11 mm solid nodule in the lower pole of the left thyroid lobe.
...There is minimally decreased activity in the lower pole left thyroid lobe, this does not represent a hyperfunctioning hot nodule.
Impression:
1. Isointense if not slightly hypointense lower pole left thyroid lobe This does not represent a hyperfunctioning hot nodule.
It was recommended that I have a nuclear scan performed to see if the lesions are malignant or not. The largest is 1 cm, I believe.
My blood tests are otherwise normal, though in the past (age 15-17) I was diagnosed with hypothyroidism and put on Synthroid for about a year. I also had PCOS when I was a teenager, but I'm doing fine now that I'm on low-hormone birth control (I'm 30, been taking the pill since I was about 23).
It is important to remember that each test looks at different things, I mean, what would be the point of 3 tests if they look for the same thing. When you have abnormal ECG and or stress test, a nuclear scan is important to establish whether you have any necrosis (dead heart muscle). If the nuclear scan revealed that a section of heart muscle has died, then bypass or stenting is a waste of time because the blood won't be of any benefit.
But the nuclear scan did not detect hemangioma. Therefore, may need CAT scan guided liver biopsy to make the diagnosis". I was sent to a 2nd GI who then ordered the 2nd CT scan with contrast and his radiologist decided "mass has imaging characteristics of hemangioma. So they have diagnosed it hemangioma.
How are two different GI's saying two different things? Is the CT scan that says it is hemangioma more reliable than the nuclear test that said it was not hemangioma?
Persantine is dipyridamole, but you will have to get extended release tablets as the two asprin and dipyridamole should not be taken together. Don’t change the medications without discussing with your doctor. So, consult him and then decide.
Hope this helped and do keep us posted.
Should Repliva 21/7 be stopped prior to a nuclear thyroid scan & uptake? Should jewelry (earrings) be removed prior? Would the scan/uptake be affected if they weren't removed?
What is nonreversible apical inferior wall and what does it mean when they say no dipyridamole-induced reversible ischemia .there is mild defect in the apical inferior wall that is not reversible at rest.
While you are taking Aggrenox (aspirin/dipyridamole), you should avoid taking over-the-counter pain medicine, especially any other products containing aspirin or non-steroidal anti-inflammatory drugs (NSAIDs).
Also, Avoid alcohol, or drink a minimal amount, as the combination of Aggrenox and alcohol could cause stomach bleeding.
I agree with Erijon, the only accurate test is a nuclear perfusion scan. Angiograms can only see vessels down to a certain size, so if you have lots of tiny collateral vessels, they will be invisible. With a blockage of around 90%, symptoms are only likely to appear when the heart is working harder, so ECG and Echo will look normal.
I was given a Thyroid scan before my treatment dose of RAI to see how much tissue was left after my thyroidectomy and to see where they wanted my treatment dose to go. This was done the day after my diagnostic dose was given and the day before my treatment dose was administered.
They like to take a few pictures including the thyroid scan, WBS, etc. to get a good idea of the target of the treatment.
Thank you for your answer!
Some of the alternatives include aspirin, Clopidogrel (Plavix), ticlodipine (Ticlid), dipyridamole (Persantine). Another alternative is Heparin injection. Different situations require different levels of anticoagulation. It is important to discuss the best treatment option with a physician.
My Primary care physician sent me for an ultrasound of my thyroid. After receiving the report, she ordered a nuclear scan. When I asked her should I be worried, she responded with "No, I will tell you if you when and if you should worry."
Are these tests routine?
I think if I was in your shoes, I would first maybe wonder if 'both' tests are accurate and have given true readings to the best of their ability. The perfusion (nuclear) scan has revealed reversible ischaemia which means blood flow to an area of heart muscle is restricted. The angiogram shows that your major coronary arteries are clear.
Another alternative that should be discussed is a 64 slice CT scan. I had three nuclear scans in three years prior to my successful ablation for a fib. All indicated good blood flow to the heart. I wanted a CT scan to rule out any artery disease as a contributor to my a fib, but my cardiologists told me it was not medically necessary. I finally convinced them that it was for my peace of mind even if they thought it was unnecessary, and I would pay for it.
In 2007 I had an emergency stent placed, and it was seen how my left artery was totally blocked, probably had been for years and I was 46. Now, a month after that, I had a nuclear scan. This looked fantastic and my cardiologist said if the nuclear scan was done first, then he wouldn't want to see me again. The reason? because I had formed collateral vessels to feed the deficit areas. So a nuclear scan can make things appear normal, but in reality the arteries could be a major mess.
