中文摘要:

目的采用3D-UTE序列联合T2^* mapping评价腰椎间盘软骨终板缺损与椎间盘退变的相关性。方法 26例受检者分别接受腰椎3D-UTE序列、T2^*mapping检查。按照椎间盘有无软骨终板缺损分为4组:A组,软骨终板无缺损;B组,软骨终板头侧缺损;C组,软骨终板尾侧缺损;D组,软骨终板头尾侧缺损。测量腰椎正中矢状层面上椎间盘髓核区的T2^*值。结果 26例受检者共130个椎间盘,其中A组67个(67/130,51.54%),B组15个(15/130,11.54%),C组24个(24/130,18.46%),D组24个(24/130,18.46%);A~D组髓核区T2^*值分别为(49.60±1.97)ms、(45.59±4.76)ms、(40.64±2.84)ms及(24.63±2.66)ms,差异有统计学意义(F=15.59,P<0.0001)。D组与A、B、C组及A组与C组髓核区T2^*值差异有统计学意义(P<0.05),余组间两两比较差异均无统计学意义。结论软骨终板缺损与椎间盘退变有关系,软骨终板头、尾侧均缺损比软骨终板头、尾侧单独缺损更容易引起椎间盘退变。

英文摘要:

Objective To explore the relation between cartilaginous endplate (CEP) defects and intervertebral disc degeneration using 3D-ultrashort echo time (3D-UTE) sequence combination with T2^* mapping sequence. Methods Totally 26 subjects underwent MR 3D-UTE sequence and T2^*-mapping. According to intervertebral disc adjacent CEP defects or not, intervertebral discs of 26 subjects divided into four groups: Group A (no CEP defects), Group B (cranial CEP defects), Group C (caudal CEP defects) and Group D (CEP defects in both cranial and caudal ends). The T2^*-relaxation time (T2^*-RT) of nucleus pulposus (NP) of lumbar disk in median sagittal plane were measured. Results In 130 intervertebral discs, Group A had 67 intervertebral discs (67/130, 51.54%), Group B had 15 intervertebral discs (15/130, 11.54%), Group C had 24 intervertebral discs (24/130, 18.46%), and Group D had 24 intervertebral discs (24/130, 18.46%). The T2^*-RT of group A—D was (49.60±1.97)ms, (45.59±4.76)ms, (40.64±2.84)ms, (24.63±2.66)ms, respectively (F=15.59, P<0.0001). Except for group D and group A, B, C, group A and group C, T2^*-RT of NP between the other two groups had no significant difference. Conclusion CEP defects and intervertebral disc degeneration have relation. Intervertebral disc degeneration is more likely to be caused by the both cranial and caudal CEP defects than the cranial and caudal CEP defects alone.
