TABLE 3:

Delineation of aneurysm shape at rotational DA and MIP, SSD, and volume-rendering 3D DA

Delineation of Shape Score*	Rotational DA (n = 28)	MIP 3D DA (n = 28)	SSD 3D DA (n = 28)	Volume-Rendering 3D DA (n = 28)
+2	16 (57)	18 (64)	24 (86)	27 (96)
+1	8 (29)	6 (21)	4 (14)	1 (4)
0	4 (14)	4 (14)	0 (0)	0 (0)
−1	0 (0)	0 (0)	0 (0)	0 (0)
Mean score ± SD	1.43 ± 0.74	1.50 ± 0.75	1.86 ± 0.36	1.96 ± 0.19

Note.—Data are number of aneurysms. Numbers in parentheses are percentages.

^*+2 indicates sufficient visualization; +1, ambiguous visualization; 0, poor visualization; −1, misinterpretation.
