Table 1:
Diagnosis of AVS (number of patients correctly diagnosed) using ASL, SWI, and conventional MRI
| MRI Sequences | DSA |
|||
|---|---|---|---|---|
| No AVS (n = 29) | AVS (n = 63) | DAVF (n = 10) | AVM (n = 53) | |
| SWI | 28 (97%) | 55 (87%) | 8 (80%) | 47 (89%) |
| ASL | 26 (90%) | 60 (95%) | 8 (80%) | 52 (98%) |
| ASL/SWI | 28 (97%) | 62 (98%) | 9 (90%) | 53 (100%) |
| Conventional MRI | 28 (97%) | 57 (90%) | 9 (90%) | 48 (91%) |
Note:—ASL/SWI indicates ASL and SWI combined; conventional MRI, conventional MRI protocol (including diffusion-weighted imaging, gradient-echo T2*, 3D FLAIR, TOF MRA, 4D and 3D contrast-enhanced MRA, and postcontrast 3D T1WI sequences).
