“…The diagnosis of hypoglossal canal lesions was mainly dependent upon CT before MRI availability. CT offers some advantages in that it allows the evaluation of bony structures, and bone destruction of the hypoglossal canal wall as well as bone fractures due to trauma 1,4,20,22 . Previous studies have shown that enhanced multilayer CT can display the venous structures in the region of the hypoglossal canal, as well as vascular anomalies 25 .…”

BACKGROUND AND PURPOSE To assess a 3D high‐resolution IR‐prepped fast SPGR high‐resolution MRI sequence for evaluating hypoglossal nerve lesions. METHODS The clinical data of 8 patients with hypoglossal nerve lesions admitted from December 2011 to February 2016 were retrospectively analyzed. MRI included contrast‐enhanced conventional sequences and a 3D IR‐prepped fast SPGR high‐resolution T1‐weighted (BRAVO) MRI sequence at 3T. RESULTS Eight patients had hypoglossal lesions detected by MRI. Conventional enhanced scanning could not clearly display the hypoglossal nerve and canal, while the enhanced 3D high‐resolution sequence could. In addition, multiple planar reconstruction clearly displayed the hypoglossal nerve, hypoglossal canal, and lesions in multiple planes. CONCLUSIONS Compared with conventional MRI, we show superior results from an advanced sequence to improve image quality in characterizing hypoglossal nerve lesions.
