Thallium Stress Test

Posted By Ellen on June 24, 1998 at 15:29:03:







I had a thallium stress test.  The interpretation was "mild degree of
anterior wall reversible ischemia consistent with coronary artery disease".
The doctor at that time said it was "of some concern".  In a later
report of his, he said that it was a false positive result.
Another doctor looked at the test and suggested that it was breast artifact.
The first doctor never said anything about breast artifact, just "of some
concern", then, "false positive".  
Are false positives common?  Does it bear re-checking?
Thanks.
