How accurate is ct angio test? i would like to know if there is a good correlation between ct angio test angioplasty or ango cathrization.recently my ct angio indicated 75 steniois but angio catherization which is more real test revealed only 10%.or less

Agree : Agree with michael david shapiro. An additional point to consider is the cardiac catheritization is the "gold standard" for which ct angiography is based on. So, in your case the cardiac cath would represent the more accurate study if interpretated correctectly. Dr. Khoury radiologist usradreview.Com.

In : In large part the answer to your questions depends on the experience and technology available at the center that is performing the ct scan. Large clinical trials have shown that coronary ct angiograms interpreted by experienced readers using state of the art technology are highly reliable to evaluate the coronary arteries. In general, the results correlate very well to invasive coronary angiography. Clearly, in your case, the ct scan overestimated the degree of narrowing in your coronary arteries. This may be due to dense calcifications in the lining of your arteries which can lead to false positive results on ct.
