Abstract: To explore the clinical value of application for 3D-CE-TOF-SPGR sequence in the diagnosis of venous cranial neurovascular compression syndrome. In our hospital 198 cases being carried out with MRTA examination were retrospectively analyzed, and there was 7 patients (5 cases of primary trigeminal neuralgia, 2 cases of facial spasm) with venous cranial nerve vascular compression syndrome confirmed by surgery.MRTA included 3D-FIESTA, 3D-TOF-SPGR and 3D-CE-TOF-SPGR sequences, one case showed 3D-FIESTA sequence, one case showed 3D-TOF-SPGR sequence and 6 cases showed 3D-CE-TOF-SPGR sequence, and independent application of 3D-CE-TOF-SPGR sequence is the best way to display(6/7, 85.71%). In MRTA Imaging Technology the 3D-CE-TOF-SPGR sequence can clearly show the objective cranial nerve and the veins responsible vessels for corresponding cranial nerve compression, which is of great value in guiding clinical MVD surgery.
