title: Gated cardiac tomographic visualization of coronary artery calcification.
abstract: Coronary artery calcification (CAC) is usually detected by fluoroscopy or on cine films during coronary angiography, but measurement of the calcification is not possible. Gated tomography of the heart provides a full sized image with high contrast spatial resolution of 0.1 mm and low contrast spatial resolution of 0.76 mm. The radiation exposure to the heart is between 1-5% of that experienced with coronary cinefluorography . Measurement of the diameter of calcium deposits is possible and calcium that could be related to arterial stenosis may be identified.
