Fig. 1 —Curved multiplanar reconstruction (MPR) along long axis of vessel
(left), and two perpendicular 2D profiles (right) at
location indicated on curved MPR (TeraRecon Aquarius workstation). Profile is
line crossing lumen, resulting in graph representing attenuation (in
Hounsfield units) along that line. Pixels with attenuation values higher than
average attenuation of contrast material in opacified lumen minus 3 SD are
supposed to be part of coronary lumen.
