Table 1: MRI/CT detection of the superior semicircular canal dehiscence^{^a}
SSC (213 Canals, 11 Excluded) Dehiscence on CT (No.) No Dehiscence on CT (No.)
Dehiscence on MRI (1.5T/3T) 11 (5/6) 7 (2/5)
No dehiscence on MRI (1.5T/3T) 0 (0/0) 195 (72/123)
↵a Detailed results for 1.5T and 3T are displayed in parentheses as follows: (1.5T/3T). Of the 224 SSCs in 112 patients, 11 were excluded because of artifacts on CT and/or MRI. In the remaining 213 canals, 11 of the 18 (11 + 7) SSC dehiscence cases seen on FIESTA were confirmed on CT. When there was no SSC dehiscence on MRI, there was no SSC dehiscence seen on CT.

SSC (213 Canals, 11 Excluded)	Dehiscence on CT (No.)	No Dehiscence on CT (No.)
Dehiscence on MRI (1.5T/3T)	11 (5/6)	7 (2/5)
No dehiscence on MRI (1.5T/3T)	0 (0/0)	195 (72/123)
