Utility of magnetic resonance cisternography using three-dimensional fast asymmetric spin-echo sequences with multiplanar reconstruction: the evaluation of sites of neurovascular compression of the trigeminal nerve.

摘要: Objective To evaluate the utility of magnetic resonance (MR) cisternography using 3-dimensional (3D) fast asymmetric spin-echo (FASE) sequences with multiplanar reconstruction (MPR) for detection sites neurovascular compression (NVC) in patients trigeminal neuralgia. Study design Both MR 3D-FASE and angiography (MRA) were performed on 150 clinical signs symptoms that suggested Results from original sequences, MRA, 4 reformatted images used interpretation. Images inversion between black white to NVC. A diagnosis NVC was made presence vascular contact nerve at root entry zone (REZ) nature involved vessels. For detectable or MRA images, relationship clinically manifested regions also evaluated. Of evaluated, 89 deemed have these patients, 3 underwent surgery identified artery nerve. The correlation significantly both coefficient imaging a little higher than MRA. 61 not NVC, 6 found brain tumors invaded However, remaining 55 had no identifiable cause asymptomatic side 27 (18%) neuralgia sequences. Conclusions technique MPR is more accurate useful site Patients should be further examined rule out tumor. Radiologists understand few subjects could show cisternography.
