磁共振T2-mapping检查对颈椎间盘退行性变的诊断价值
Value of Magnetic Resonance T2-mapping Examination in Diagnosis of Degeneration of Cervical Intervertebral Disc
摘要
Abstract
Objective To investigate value of magnetic resonance T2-mapping examination in evaluation of de-generation of cervical intervertebral disc. Methods A total of 42 healthy people underwent routine cervical magnetic res-onance imaging (MRI) and T2-mapping scan from January to November 2016, and Pfirrmann classification for cervical intervertebral disk was performed for the people, and then correlation between T2 value and Pfirrmann classification was analyzed. Values of T2 relaxation times of nucleus pulposus at different ages and anatomic sections were compared. Re-sults There were 210 cervical intervertebral discs in the 42 healthy people. Numbers of grade I, II, III, IV and V Pfir-rmann classification were 20, 85, 98, 7 and 0 respectively. Spearman correlation analysis showed that there was a nega-tive correlation between the mean T2 value of nucleus pulposus with Pfirrmann classification (r= -0. 67, P<0. 01);the mean T2 value of nucleus pulposus was decreased gradually with increasing Pfirrmann grading;there were significant differences in mean T2 values of nucleus pulposus among different Pfirrmann grading groups (P<0. 01). Receiver oper-ating curve ( ROC) graph shows that T2 values of area under curve in diagnosis of grade I and II, II and III, III and IV intervertebral disks, were 0. 78, 0. 80 and 0. 79 (P<0. 05). In 18-30 age group, there were significant differences in T2 values among different segments of cervical intervertebral disc (P<0. 01). T2 values in different segments of cervical intervertebral disc in 31-40 age group were significantly lower than those in 18-30 age group (P<0. 01). Conclusion MRI T2-mapping examination has value in evaluation of degeneration of cervical intervertebral disc and changes of ana-tomic segments.关键词
