浅谈颈部MRI诊查中THRIVE技术的应用价值

Evaluation of MRI T1 high resolution isotropic volume excitation technique in the diagnosis of cervical region

目的探讨T1高分辨力各向同性容积激发(T1 high resolution isotropic volume excitation,THRIVE)技术在颈部MRI扫描中的应用价值。材料与方法采用PHILIPS 3.0 T MRI成像仪对80例临床疑诊颈部疾病患者进行MRI平扫及联合脂肪抑制的增强扫描,包括THRIVE及矢冠轴3个方位的二维TSE-T1WI序列,之后对两种方法在压脂效果、图像伪影两方面的差异性进行统计学分析。结果在脂肪抑制的效果及对图像伪影处理方面,THRIVE技术明显优于二维TSE-T1WI。结论 3D-THRIVE技术联合脂肪抑制序列抑脂效果好,伪影少,能精细显示颈部结构及病灶,提高诊断价值。

Objective： To explore the value of the THRIVE technique in the diagnosis of cervical region. Materials and Methods： Chose 80 patients with clinically suspected cervical disease, routine non-enhanced MRI scan, T1 WI and THRIVE sequence used in the enhanced scan joint fat suppression were successfully completed in these patients by PHILIPS 3.0 T MRI. Using statistical method to test that, whether the statistical significance of the differences existed in the fat suppression and artifacts of the two techniques. Results： THRIVE technique used in the enhanced scan joint fat suppression is better than the T1 WI sequence at the sides of the fat suppression and artifacts. Conclusion： The THRIVE technique joint fat suppression can eliminate the signal of fat perfectly, and also with less artifacts, even none. On the other side, it shows the detail in the structure and diseased region of neck, and can improve the value of MRI used in cervical region.
