MRI/CT detection of the superior semicircular canal dehiscencea
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.
