Question 1

how many msv in a thallium scan of the heart?

Accepted Answer

Millisieverts: The dosage depends on the lab, technique, dosage of thallium administered and other factors. It can be up to 15millisieverts on the average in the literature sometimes higher.

Question 2

is a 6% ischaemic burden on the heart under a thallium scan reversible ?

Accepted Answer

Thallium stress: &gt;5% ischemic burden is significant.

Question 3

what should i avoid before a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Accepted Answer

Caffeine: You should avoid caffeine and beta blockers, just because they interfere with the test.

Question 4

is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Accepted Answer

It is never safe to : Although it is no more risky to smoke after a scan, it is never safe to smoke.

Question 5

what happens if thallium scan show normal blood flow than is it necessary to still have echocardiography to rule out heart disease in hypertensive patient?

Accepted Answer

Cardiac function: Thallium will only show if your heart muscle is getting appropriate blood flow.  The echo will show how your heart is functioning and if the valves are working well

Question 6

aog 29 weeks every test result normal , in new scan the result is bpd , hc is >97th% ile hadlock for aog , afi 22.38 high normal/ what is risk?

Accepted Answer

Don't panic!: I did not understand the "ile  hadlock" part of your question.  But a large head and borderline high afi do not sound particularly concerning. First thought is you may be a few weeks further along than originally calculated.  Hi afi's can be due to maternal diabetes, or rarely fetal abnormalities.  Please discuss  your concerns with your OB doc.

Question 7

i am going to medical test result is unfit.in my ct scan findings bilateral apical pleural thickening seen.that means?what can i do for fit

Accepted Answer

Pneumoconiosis: Bilateral pleural apical thickening is indicative of pneumoconiosis, most commonly silicosis, with eggshell apical pleural thickening.  Pulmonary function tests with pre-and post bronchodilator, body plethysmography, DLCo for evaluation of lung capacity, along with finding the etiology of your for thickening is to 1st step prior to clearance for physical clearance for fit for duty.

Question 8

can scar tissue from pericarditis cause a blockage and be the reason for my positive ischemia stress test result even though cac score from cta scan 0?

Accepted Answer

: This would be an unlikely scenario or cause for an abnormal stress test as the pericardium would have to compress a coronary artery or branch. On the other hand, you're age and CAC would make coronary blockage unlikely unless spasm or endothelial dysfunction occurred. Did you have a nuclear stress study or echo study? I vote for a nuclear study&amp; hope a CT angiogram or catheterization won't be need

Question 9

does a normal frataxin  test result rule out the possibility  of friedreich ataxia.and does a normal  result of a cat scan rule out cerebellar ataxia ?

Accepted Answer

No and no: There are several forms of cerebellar ataxia.  There are markers that have been found, but most cases are not diagnosed by the marker gene but by appropriate clinical evaluation.  Early in the course ct and MRI may be normal.

Question 10

what does a "350" on my vision test result actually mean?

Accepted Answer

Lens correction: It is most likely the power of the lens correction you require. Either + 3.50 (farsighted, hyperopic) or -3.50(nearsighted or myopic).
