Delayed gadolinium contrast-enhanced 3D-T1 SPACE STIR sequence can better visualize abnormal cranial nerves: a case...

With the advancement of magnetic resonance imaging (MRI) techniques, general radiographic methods are no longer sufficient for accurately displaying the structure and pathway of cranial nerves. Various sequences, including 3-dimensional sampling perfection with application-optimized contrast using different flip angle evolution (SPACE), have been developed through MRI technology to effectively display the location and severity of damaged cranial nerves. This current case report describes a 36-year-old male patient with multiple cranial nerve injuries resulting from an invasive Mucor infection. While performing MRI scanning on this patient, a 1-h delayed enhanced MRI 3D-T1 SPACE short tau inversion recovery (STIR) sequence proved more effective in eliminating background interference and assessing neurological damage with greater clarity than conventional enhancement methods. This approach may prove beneficial in accurately evaluating the extent of cranial neuropathy, thus facilitating clinical applications.
