Flashing tomosynthesis, a procedure that consists of a recording step and a
reconstruction step, facilitates the tomographic imaging of coronary
arteries. In a comparative study 10 postmortem coronary arteriograms were
examined with 35-mm cine technique and with flashing tomosynthesis. The
degrees of stenosis found with both of these techniques were compared with
morphometrically obtained values. A higher correlation coefficient existed
for the degrees of stenosis obtained with tomosynthesis and morphometry (r
= 0.92, p less than 0.001, SEE = 9%) than for those obtained with cine
technique and morphometry (r = 0.82, p less than 0.001, SEE = 16%). The
technique has also been successfully carried out in 5 patients with
coronary artery disease.
