| 目的 分析跟腱断裂(ATR)超短回波时间(UTE)T2* mapping定量参数与术后跟腱修复的相关性。方法 前瞻性纳入34例男性ATR患者(ATR组),分别于跟腱修复术前及术后1、3、6、12个月行UTE T2* mapping检查、跟腱完全断裂评分(ATRS)及疼痛视觉模拟评分(VAS);同时对35名健康男性志愿者(对照组)行UTE T2* mapping检查。比较ATR组内各时间点临床评分及断裂跟腱UTE T2*值,以及组间断裂跟腱UTE T2*值;采用Spearman相关分析观察各时间点UTE T2*值与ATRS及VAS的相关性。结果 ATR组术后1、3、6、12个月ATRS及VAS均低于术前(P均＜0.05);其中术后1、3、6、12个月ATRS持续下降(P均<0.001),且除术后3个月与6个月外,其余时间点VAS两两比较差异均有统计学意义(P均＜0.001)。ATR组术后1个月断裂跟腱UTE T2*值高于术前(P=0.002),术后3个月低于术后1个月(P=0.033)而与术前差异无统计学意义(P=0.989),术后6个月低于术前、术后1及3个月(P均＜0.001),至术后12个月为最低(P均＜0.001)。术后6及12个月,ATR患者断裂跟腱UTE T2*值与ATRS及VAS均呈中度正相关(r=0.506~0.697,P均＜0.05)。结论 ATR术后6及12个月,断裂跟腱UTE T2*值与修复情况存在关联;UTE T2* mapping可为无创监测肌腱修复提供定量参考。 |

| Objective To explore the correlations of ultra-short echo time (UTE) T2* mapping quantitative parameters with postoperative reparation of achilles tendon rupture (ATR). Methods Thirty-four male patients with ATR (ATR group) were prospectively enrolled. UTE T2* mapping examination, achilles tendon total rupture score (ATRS) and visual analogue scale (VAS) were performed before and at 1, 3, 6 and 12 months after operation. Thirty-five healthy male volunteers who underwent UTE T2* mapping were served as control group. Clinical scores and UTE T2* values of the ruptured achilles tendon at different time points were compared within ATR group, also between groups. Spearman correlation analyses were used to observe the correlations of UTE T2* values with ATRS and VAS at different follow-up time points. Results In ATR group, ATRS and VAS scores 1, 3, 6 and 12 months after operation were lower than those before operation (all P＜0.05). Postoperative ATRS decreased continuously among 1, 3, 6 and 12 months after operation (all P<0.001). And except for 3 and 6 months after operation, significant differences of VAS were found between the other pairwise comparisons (all P＜0.001). UTE T2* value of the ruptured achilles tendon in ATR group 1 month postoperation was higher than that before operation (P=0.002), which 3 months postoperation was lower than that 1 month postoperation (P=0.033) but not significantly different from that before operation (P=0.989). UTE T2* value of the ruptured achilles tendon 6 months postoperation was lower than that before operation, also 1 and 3 months postoperation (all P＜0.001). UTE T2* value of the ruptured achilles tendon 12 months after operation was the lowest (all P＜0.001). Six and 12 months after operation, UTE T2* values of the ruptured achilles tendon were moderately positively correlated with ATRS and VAS (r=0.506—0.697, all P＜0.05). Conclusion Six and 12 months after ATR reparation, UTE T2* values of the ruptured achilles tendon were associated with postoperative repair status. UTE T2* mapping could provide quantitative references for noninvasive monitoring tendon repair. |
