Atherosclerosis imaging using 3D black blood TSE SPACE vs 2D TSE

Figure 2 Scatter plots of lumen area comparing three-dimensional SPACE and two-dimensional turbo spin echo images. Morphometric analysis using a FDA-approved, customized software program (QPlaque MR, Medis medical imaging systems, The Netherlands) was performed on all carotid, aortic and femoral arterial wall images of 16 patients who were at risk for cardiovascular or atherosclerotic disease for three-dimensional (3D) SPACE and conventional 2D multi contrast turbo spin echo (TSE) sequences. A: Scatter plot of RCC lumen area comparing 3D SPACE and 2D TSE images. There was a moderate positive linear correlation (R = 0.729) between the values of the RCC lumen area obtained from the 3D SPACE and 2D TSE sequences; B: Scatter plot of LCC lumen area comparing 3D SPACE and 2D TSE images. There was a strong positive linear correlation (R = 0.805) between the values of the LCC lumen area obtained from the 3D SPACE and 2D TSE sequences; C: Scatter plot of aorta lumen area comparing 3D SPACE and 2D TSE images. There was a strong positive linear correlation (R = 0.776) between the values of the aorta lumen area obtained from the 3D SPACE and 2D TSE sequences; D: Scatter plot of RF lumen area comparing 3D SPACE and 2D TSE images. There was a moderate positive linear correlation (R = 0.735) between the values of the RF lumen area obtained from the 3D SPACE and 2D TSE sequences; E: Scatter plot of LF lumen area comparing 3D SPACE and 2D TSE images. There was a moderate positive linear correlation (R = 0.699) between the values of the LF lumen area obtained from the 3D SPACE and 2D TSE sequences. RCC: Right common carotid; LCC: Left common carotid; RF: Right femoral; LF: Left femoral.
