MDCT not quite ready for CAD screening

Filed under: Cardiology, JAMA — medblog @ 9:49 pm

JAMA 6/26 – Interventional radiologists can breathe a little easier…. for now. A study by Garcia and the CATSCAN investigators in JAMA explored the use of 16 row multidetector CT to assess for coronary artery stenosis. Having a non-invasive method to evaluate the condition would make life much easier for many thousands of CAD sufferers each year, not to mention fattening some radiologist pocketbooks.

But unfotunately, in a study of over 200 patients, the test was only moderately (89%) sensetive and not very specific (65%) in the detection of greater than 50% stenosis. In addition, only 71% of the lesions were evaluable. Clearly not ready for primetime yet, but the technology is probably not that far off.
