Thallium Stress Tests - Reliability

by Cody, Sep 24, 1999 12:00AM
Dear CCF Physicians,

How reliable are thallium stress tests after angioplasty?  Does the reliability increase if thallium stress tests given a year apart both show similar and normal results and also regular stress tests between the yearly thalliums also showed normal and similar results?  Lastly, is a thallium stress test as reliable as a PET scan?

Thanks - HC

The sensitivity and specificity of a thallium test for detection of coronary artery disease is about 92% and 88% respectively.  This does not change following an angioplasty and is about the same as PET scaning.
