摘　　要：目的探讨3.0T磁共振弥散张量成像在三叉神经痛面肌痉挛中的临床诊断价值。方法选2016年4月~2018年8月我院诊治的52例三叉神经痛面肌痉挛患者资料进行分析,将其设置为实验组,选取同期入院的51例健康体检者为对照组。采用3.0T磁共振弥散张量成像检测3D-TOF成像序列结合3D-CISS序列中脑桥小脑角(CAP)池内面神经与周围血管关系,分析3.0T磁共振弥散张量成像在三叉神经痛面肌痉挛中的临床诊断价值。结果实验组患侧与健侧Hosoya评分比较差异具有统计学意义(P<0.05);实验组健侧Hosoya评分与对照组双侧Hosoya评分相比差异无统计学意义(P>0.05);实验组患侧Hosoya评分与对照组双侧Hosoya评分比较差异有统计学意义(P<0.05)。面肌痉挛患者中32例行面神经微血管减压术后结果显示15例血管接触或压迫。3.0T磁共振弥散张量成像对神经血管压迫敏感度为94.1%,特异度为86.7%,阳性预测值为88.9%,阴性预测值为92.9%。结论采用3.0T磁共振弥散张量成像诊断、三叉神经痛面肌痉挛患者效果理想,其敏感性及特异性高,可在临床推广应用。Objective To explore the clinical diagnostic value of 3.0T magnetic resonance diffusion tensor imaging in trigeminal neuralgia hemifacial spasm.Methods From April 2016 to August 2018,52 patients with trigeminal neuralgia and hemifacial spasm in our hospital were selected for analysis and set as the experimental group.51 healthy persons admitted in the same period were selected as the control group.The clinical value of 3.0T MR diffusion tensor imaging(DTI)in the diagnosis of hemifacial spasm in trigeminal neuralgia by detecting the relationship between the facial nerve and peripheral vessels in the cerebellopontine angle(CAP)cistern with 3D TOF sequence and 3D CISS sequence were observed.Results There was significant difference in Hosoya score between the two groups(P<0.05).There was no significant difference in bilateral Hosoya score between the two groups(P>0.05).There was significant difference in Hosoya score between the experimental group and the control group(P<0.05).Microvascular decompression(MVD)of facial nerve was performed in 32 patients with hemifacial spasm.The sensitivity,specificity,positive predictive value and negative predictive value of 30t MR diffusion tensor imaging for neurovascular compression were 94.1%,86.7%,88.9%and 92.9%,respectively.Conclusion The diagnosis and examination results of 3.0T magnetic resonance diffusion tensor imaging for patients with trigeminal neuralgia hemifacial spasm are satisfactory.
