摘　　要：目的探索STAR VIBE序列在脊柱增强磁共振扫描中的应用价值。方法根据脊柱增强MRI病例的实际扫描序列,分别抽选TSE_T1WI常规序列组和STAR VIBE序列组各34例,共68例病例,主观评价采用五分法分别对两组病例图像进行主观评分,客观评价采用分别测量两组病例图像信噪比(Signal to Noise Ratio,SNR)和椎体标准差(Standard Deviation,SD),分析两组病例图像主观评分和SNR、SD的统计学差异。结果主观评价STAR VIBE序列扫描图像基本为(4.5±0.5)分,TSE_T1WI序列扫描图像基本为(3±1)分,STAR VIBE序列组主观评分均高于TSE_T1WI常规序列组,两位医生评分一致性好(Kappa值为0.81、0.86)。客观评价STAR VIBE序列组SNR主要为10.1~20.0,TSE_T1WI组SNR主要为0.1~10.0,STAR VIBE组SNR均高于TSE_T1WI组,差异具有统计学意义(P<0.01);STAR VIBE组椎体SD主要为0.1~20.0,TSE_T1WI组椎体SD主要在30.1以上,STAR VIBE组椎体SD均低于TSE_T1WI组,差异具有统计学意义(P<0.01)。结论在脊柱增强MRI中,STAR VIBE序列扫描图像质量优于TSE_T1WI常规扫描序列,椎体结构及病灶显示更清晰。Objective To explore the application value of STAR VIBE sequence in spinal enhanced MRI acquisition.Methods TSE was selected according to the actual scanning sequence of spinal enhanced MRI,there were 34 cases in T1WI routine scanning group and 34 cases in STAR VIBE scanning group,as 68 cases in total.The subjective evaluation was used or employed to score the images of the two groups with the five-point method.The objective evaluation was employed or used to measure the signal to noise ratio(SNR)and standard deviation(SD)of the images of the two groups respectively.The differences of subjective image score,SNR and SD between the two groups were analyzed.Results The subjective evaluation of STAR VIBE sequence scan image was(4.5±0.5)points,TSE-T1WI sequence images were basically(3±1)points,and the subjective scores of STAR VIBE sequence group were higher than those of TSE_T1WI routine sequence group.The two doctors’scores were consistent(Kappa values were 0.81 and 0.86).The SNR of STAR VIBE sequence group was 10.1~20.0,the SNR of TSE_T1WI group was 0.1~10.0.The SNR of STAR VIBE scanning results was higher than that of TSE_T1WI group,the difference was statistically significant(P<0.01).The SD of vertebral body standard deviation in STAR VIBE group was mainly 0.1~20.0,the vertebral SD of TSE_T1WI group was more than 30.1,and the SD of vertebral body in STAR VIBE group was lower than that in TSE_T1WI group.The difference was statistically significant(P<0.01).Conclusion In spinal enhanced MRI,the image quality of STAR VIBE sequence is better than TSE_T1WI routine scanning sequence,and the vertebral structure and lesions show more clearly.
