Abstract

Thirty-four patients with coronary artery disease were studied with standard 35 mm coronary cineangiography and flashing tomosynthesis, to assess the value of the latter technique to detect stenotic coronary arteries. All occluded vessels and all coronary stenoses seen by cineangiography were also found by flashing tomosynthesis. A correlation coefficient of r=0.85 (P>0.001) was determined between the degrees of stenosis obtained by the two techniques. With flashing tomosynthesis, less contrast medium was needed, the investigation time was shorter, and the radiation exposure markedly reduced. At present, dynamic events, such as collateral blood flow, cannot be evaluated. We conclude that coronary arterial stenoses and occlusions can be reliably evaluated by flashing tomosynthesis. Further technological developments are necessary for the technique to gain clinical acceptance.

Key Words: Coronary angiography • coronary stenosis • tomography • tomosynthesis
