CAT scan

University of Michigan Health System

Michigan hospitals reduced the inappropriate use of a risky and expensive CAT scan by nearly 60-percent in a recent study.

Kavitha Chinnaiyan is a cardiologist at Beaumont Hospital.

She says too often, doctors order heart CAT scans just to rule out heart disease - even if their patients have no symptoms.

She says that's not a good idea - and not just because the scans cost $500 to $1,500 per scan.
