How long does a calcium score scan take, and how do I prepare?

It takes about 10 minutes, and there's nothing to prepare: no fasting, no special steps. You lie on your back on the CT table, with small sticky pads on your chest to track your heartbeat. Then you hold your breath for a few seconds while the images are taken. It doesn't hurt.

Combining it with a blood test or a full-body MRI on the same day? Then just follow the preparation for that test, such as fasting before your blood draw. You'll get all the details after booking.
