Purpose: To assess the best effective MRI sequence for the visualization of the 9th-10th-11th cranial nerves (glossopharyngeal-vagus-accessory nerves) in their intraforaminal\canalicular courses. Materials and Methods: Balanced fast-field echo(b-FFE),3D-T2W DRIVE,T2W 2D TSE and Post-contrast T1W sequences were all applied and we tried to get the best sequence for the exact assessment of the 9th-10th-11th cranial nerves. 600 nerves of 100 patients without the symptoms of neurovascular compression were examined using the above sequences. Imaging analysis is graded as; Nerves analyzed by certainty(score of 2),nerves analyzed partially(score of 1) , nerves not identified(score of 0). Results: In all three nerves, the best sequence for the visualization of the cisternal and intraforaminal course is b-FFE among others, with %58-73-62 all together 64.3%success in showing the fascicles of 9th-11th nerves. This sequence with very short time of repetition (TR),symmetrical and balanced gradient around the echo time(TE),allows very fast imaging and a high signal to noise ratio(SNR).T2W TSE sequence is superior to the DRIVE T2W sequence in assessing the cisternal and intraforaminal part of all three nerves. Post-contrast T1W sequence is probably the worst sequence in showing all three nerves. Conclusion: B-FFE; Gradient echo sequence with high spatial resolution, is the optimal sequence for determining the courses of 9th-11th cranial nerves.
