Figure 4

Representative case of three-dimensional (3D) color-coded maps (68 years old, male). To reconstruct 3D IB-IVUS color-coded images, the IB-IVUS images were transformed into Cartesian coordinates (64 x 64 pixels) using customized computer software and compared with MDCT images in the Cartesian coordinates (256 x 256 pixels). We then manually excluded the vessel lumen and area outside of the intima in both the 2D IB-IVUS and MDCT images. Three dimensional constructions were automatically performed by computer software (T3D, Fortner Research LLC, Sterling, Virginia). (A) 3D color-coded map constructed by integrated backscatter intravascular ultrasound of coronary plaque with intermediate stenosis. (B) Color-coded curved multiplaner reconstruction image of coronary plaque. (C) 3D color-coded map constructed by multidetector computed tomography for the same lesion as in (A). (D) 3D color-coded map constructed by multidetector computed tomography that showed only lipid pool in the coronary plaque that was same lesion as (C).
