摘　　要：目的探讨延迟增强MRI对基质诱导自体膝关节软骨移植术的临床评估效果。方法随机选取我院2012年1月至2014年2月期间收治的行自体膝关节软骨移植术患者45例作为实验组，另选取同期软骨损伤患者45例作为对照组，对两组患者进行MRI扫描，对扫描结果进行对比分析。结果实验组患者术后CR值（0．92±0．08）较术前（1．33±0．15）明显降低，且随着患者病情分级的不断升高，其CR也随之增高（P〈0．05）；各部位的MRI增强扫描结果明显优于平扫，差异具有统计学意义（P〈0．05）。结论对基质诱导自体膝关节软骨移植术患者进行MRI增强扫描，能够为临床诊断提供高质量的膝关节软骨检查图像，同时通过对手术前后软骨强化率进行分析，有助于对手术效果进行有效评估。Objective To investigate the clinical evaluation of delayed-enhanced MRI in matrix induced autologous knee joint cartilage transplantation. Methods 45 patients undergoing matrix induced autologous knee joint cartilage transplantation in our hospital from January 2012 and February 2014 were randomly selected as experimental group, 45 cases of cartilage injury in the same period were selected as control group. Both two groups took MRI scan, with scan results compared. Results CR value after surgery in experimental group was significantly lower than that before surgery [（0.92±0.08） vs.（1.33±0.15）], and CR value increased as the classification of patients＇ condition rose （P〈0.05）; scan results of delayed-enhanced MRI in each part were significantly better than those of nonenhanced scan, with statistically significant differences （P〈0.05）. Conclusions Delayed-enhanced MRI in patients undergoing matrix induced autologous knee joint cartilage transplantation can offer high-quality images of knee cartilage checking for clinical diagnosis; enhanced rate of cartilage before and after surgery were analyzed to effectively evaluate clinical effect.
