摘要

目的：比较3D-FIESTA和FRFSE T2WI序列对后颅窝第V~XII对脑神经脑池段的显示效果。材料和方法：对40例320对颅神经行3D-FIESTA和FRFSE T2WI扫描，由2名放射诊断副主任医师结合多平面重组（MPR）进行独立回顾性分析，MR表现分成3级（0级：无显示，1级：部分显示，2级：全部显示）。结果：320对脑神经在3D-FIESTA和FRFSE T2WI中显示率（1级和2级）分别为：第V对神经（100%，100%）、第VI对神经（98.75%，42.00%）、第VII对神经（100%，100%）、第VIII对神经（100%，100%）、第IX~XI对神经组（低位神经）（100%，74%）、第XII对神经（95%，3.75%）。结论：T2WI对后颅窝脑神经显示效果，3D-FIESTA优于FRFSE，可用于获得脑池段脑神经高分辨率MR成像。

Abstract

Objective: To compare 3D fast imaging with steady state acquisition(3D-FIESTA) to fast recovery fast spin echo T2WI(FRFSE T2WI) sequences in the imaging of cisternal parts of cranial nerves V~XII. Methods: MRI in 3D-FIESTA MPR and FRFSE T2WI sequences of 40 patients were evaluated retrospectively. 320 pairs of nerves were evaluated. Two radiologists, working independently, divided the imaging findings into 3 grades: 0(not visualized), 1(partially visualized), and 2(completely visualized). Results: The rate of visualization of these cranial nerves with 3D-FIESTA and FRFSE T2WI sequences were as follows(partially and completely visualized): nerve V(100% and 100%); nerve VI(98.75% and 42.0%); nerve VII(100% and 100%); nerve VIII(100% and 100%); nerve IX~XI complex(100% and 74%); nerve XII(95.0% and 3.75%). Conclusion: 3D-FIESTA sequence is superior to FRFSE T2WI sequence in the imaging of cisternal parts of the posterior fossa nerves. 3D-FIESTA sequences can be used for obtaining high-resolution MR cisternography images.
