Fig. 8 — Suppression of flow artifacts within aneurysm using preparation pulse (MSDE). 3D time-of-flight MR angiography revealed a fusiform aneurysm of the basilar artery (arrow in a). The axial image of CT angiography shows homogeneous enhancement in the lumen of the basilar artery aneurysm (arrow in b). 3D-T1-weighted VWI shows an isointense signal in the aneurysm (arrow in c). Post-contrast-enhanced 3D-T1-weighted VWI shows wall enhancement (dotted arrow in d) and enhancement within the aneurysm (arrow in d). The combined use of MSDE suppressed the signal within the aneurysm and showed no artifactual enhancement within the aneurysm (e). MSDE, motion-sensitized driven equilibrium; VWI, vessel wall imaging.
