CT OR ANGIOGRAPHY

ANCHOR LEAD:   CT IS AS GOOD AS TRADITIONAL ANGIOGRAPHY IN FINDING BLOCKED BLOOD VESSELS, ELIZABETH TRACEY REPORTS

The latest generation of CT scanners, so called 64 slice CT, are capable of finding blocked arteries in the heart as well as the more invasive cardiac catheterization, an international team led by Johns Hopkins researchers has shown.  Julie Miller, the study’s lead author and a cardiologist at Hopkins, explains.

MILLER: With a single rotation of the CT scanner, we can obtain 64 simultaneous pictures of the heart.  This technology allows us to see the small structures of the heart including the coronary arteries.  And with that we can detect the blood flow through those coronary arteries and the blockages of that blood flow.  Those blockages of course can lead to chest pain and heart attacks in patients.

Miller predicts that for diagnosis of blocked arteries in the heart, CT will soon be the method of choice.  Catheterization will still be required for interventions like placing a stent, however.  I’m Elizabeth Tracey reporting.
