摘要
目的探讨多排螺旋CT(MDCT)在诊断前交叉韧带(ACL)损伤中的价值。方法 74例具有临床资料的膝关节外伤患者,均行MDCT和关节镜检查。结果 74例中,MDCT诊断61例ACL损伤,关节镜确诊59例ACL损伤。MDCT诊断ACL损伤的敏感性、特异性、阳性预测值、阴性预测值分别为96.7%、84.6%、96.7%、84.6%;ACL损伤程度的判断上,ACL急性损伤,MDCT检查与关节镜检查有较好的相关性,两者无显著性差异;但ACL慢性损伤诊断中,MDCT诊断正确性较差。结论 MDCT对诊断急性ACL损伤是比较理想的方法之一。
Objective To investigate the value of multi-detector computer tomographic （MDCT） in diagnosis of anterior cruciate ligament（ACL） injury. Methods 74 patients who had been highly suspected internal derangement of the knee was performed both MDCT and arthroscopy examination. The CT images were prospectively interpreted and analyzed for accuracy of MDCT diagnosis of ACL tears. Results Among the 74 patients, 64 patients with ACL injury were cheched by MDCT and 59 patients were confirmed the ACL injunry by arthroscopy. The sensitivity ,specificity, positive predictive value, negative predictive value of MDCT is 96.7%, 84.6%, 96.7%, 84.6%, respectively. The diagnosis accuracy of acut ACL injury is no statistical difference beweent CT and arthroscopy（P〉0.05）, but there was statistical difference in diagnosis chronic ACL imjury. Conclusion The MDCT was a perfect way of in the ACL of acute knee＇s injury.
