Clinical Value of 3.0T MR T_2 Mapping Imaging Technique in Evaluation of Early Cartilage Lesion of Knee Joint

目的研究3.0T MR T_2mapping成像技术对膝关节早期软骨病损评价的临床应用价值。方法选取我院80例膝关节早期软骨病损的患者作为研究组,80例健康正常者作为对照组。两组均采取3.0 T MR成像仪进行对膝关节软骨的T_2值进行测量,观察比较两组的T_2值。结果研究组患者膝关节软骨的T_2值为(48.37±4.63)ms,显著高于对照组的(36.28±3.58)ms(P<0.05)。结论 3.0T MR T_2mapping成像技术可有效反映膝关节早期软骨病损的T_2值变化,具有重要的临床应用价值。

Objective To evaluate the clinical value of 3.0T MR T_2 mapping imaging technique in evaluation of early cartilage lesion of knee joint. Methods E ighty patients with early knee cartilage lesions were selected as the study group, and 80 healthy people were selected as the control group. B oth groups received 3.0T MR imager to determine the T_2 value of knee joint cartilage, and the T_2 values were compared between two groups. Results The T_2 value of knee joint cartilage of the study group was（48.37 ± 4.63） ms, significantly higher than（36.28 ± 3.58） ms of control group（P〈0.05）. Conclusions 3.0T MR T_2 mapping imaging technique can effectively response T2 changes of early knee cartilage lesions, which has important value in clinic.
