The study of diagnostic value of brainstem 3D-TOF thin scan of magnetic resonance in primary trigeminal neuralgia

Objective To evaluate diagnostic value of brainstem 3D-TOF thin scan of magnetic resonance in primary trigeminal neuralgia.Methods Observe 3D-TOF thin scan of magnetic resonance in 150 cases.All studies were performed on SIMENS3.0 T MR imaging system.3D-TOF brainstem thin scan was performed by 8 channel head coils with the following parameters: 23/3.6(repetition time msec/echo time msec),15° flip angle,field of view of 165×220 mm.section...
