Table 2.
A tabular description of the petrosal-galenic anastomosis as seen in balanced fast field echo magnetic resonance imaging
| Petrosal-galenic anastomosis | Prevelance (n = 50) |
|---|---|
| Present | 38% (19) |
| Absent | 18% (9) |
| Non-assessable | 26% (13) |
| Inadequate bFFE1 | 13 of 13 |
| PTv absent | 16% (8) |
| PTv not part of the SPVC | 2% (1) |
bFFE balanced fast field echo, PTv pontotrigeminal vein, SPVC superior petrosal vein complex
1The number of cases with non-assessable petrosal-galenic anastomosis due to technical shortcomings of the bFFE magnetic resonance imaging examinations
