Figure 1 Visualization of coronary plaque and assessment of remodeling by multidetector spiral computed tomography (MDCT). (A–D) Patient with a not significantly stenotic lesion in the proximal left anterior descending coronary artery. (A) X-ray coronary angiogram (arrow = site of the lesion); (B) axial MDCT image (1-mm slice thickness) at the level of the lesion (arrow); (C) MDCT reconstruction orthogonal to the vessel at the site of maximum luminal obstruction showing circumferential plaque (cross-sectional vessel area 41 mm2); (D) MDCT reconstruction orthogonal to the vessel in the reference segment (cross-sectional vessel area 35 mm2). Remodeling Index 1.2. (E–H) Patient with a high-grade stenosis of the left anterior descending coronary artery. (E) X-ray coronary angiogram (arrow = left anterior descending coronary artery stenosis); (F) axial MDCT image (1.0 mm slice thickness) at the level of the partly calcified lesion (arrow); (G) MDCT reconstruction orthogonal to the vessel at the site of maximum luminal obstruction (cross-sectional vessel area 22 mm2); (H) MDCT reconstruction orthogonal to the vessel in the reference segment (cross-sectional vessel area 22 mm2). Remodeling Index 1.
