Retrospective comparison of three-dimensional imaging sequences in the visualization of posterior fossa cranial nerves

Rates of visualization of posterior fossa cranial nerves in cases of complete visualization were as follows: nerve V (100% for both sequences), nerve VI (94% in SPACE, 86% in CISS sequences), nerves VII-VIII (100% for both sequences), IX-XI nerve complex (96%, 88%); nerve XII (58%, 46%) (p < 0.05). SPACE sequences showed fewer artifacts than CISS sequences (p < 0.002).
