FIG 9. A, 2D reformation of a lateral aneurysm in the coronal plane. The artifact in this image is caused by up-and-down motion of the intravascular sonographic catheter during the cardiac cycle (asterisk denotes the intravascular sonographic catheter; LA, lateral aneurysm; PA, parent artery; dashed line identifies the limit of the aneurysm ostia).

B, Corresponding DSA.
