TABLE 4:

Delineation of relationship between aneurysm and adjacent arteries at rotational DA and MIP, SSD, and volume-rendering 3D DA

Delineation of Location Score*	Rotational DA (n = 28)	MIP 3D DA (n = 28)	SSD 3D DA (n = 28)	Volume-Rendering 3D DA (n = 28)
+2	12 (43)	21 (75)	26 (93)	27 (96)
+1	10 (36)	6 (21)	2 (7)	1 (4)
0	6 (21)	1 (4)	0 (0)	0 (0)
−1	0 (0)	0 (0)	0 (0)	0 (0)
Mean score ± SD	1.21 ± 0.79	1.71 ± 0.54	1.93 ± 0.26	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.
