Figure 6c: Images in 65-year-old man with transient ischemic attacks. (a) Coronal maximum intensity projection of first-pass gadofosveset trisodium–enhanced MR data at spatial resolution of 1.0 mm3 shows significant stenosis (arrow) in proximal right internal carotid artery. (b) Findings on color-coded Doppler US image (reference standard), showing 75% or greater stenosis with a maximal flow velocity of 1.7 m/sec, confirm the findings in a. (c) Findings on MPRs, on which first-pass data (3.4/1.3, 30° flip angle) are compared with steady-state data (6.5/2.2, 25° flip angle), also confirm the internal carotid artery stenosis (arrows) seen in a.
