摘要
目的：探讨磁共振 T2-mapping 及弥散加权成像（DWI）成像在膝关节早期软骨退变诊断中的应用价值。方法选取临床拟诊早期膝关节炎患者56例，设定为观察组，另选择56例健康志愿者为健康对照组，分别对两组对象进行膝关节磁共振 T2-mapping 以及 DWI 成像，采集两组对象的 T2值和 ADC 值，并进行比对分析。结果观察组 T2值在股骨内侧面（37．18±4．09）、胫骨内侧面（32．16±2．75）以及髋骨面（34．56±4．21）显著低于健康对照组的股骨内侧面（49．87±5．02）、胫骨内侧面（47．34±5．01）、髋骨面（51．23±5．19）（t ＝20．16、18．36、23．65，均 P ＜0．05）。结论磁共振 T2-mapping 及 DWI 成像可以发现早期膝关节软骨退变会导致 T2与 ADC 值上升，因此对还未出现软骨形态学改变的软骨损伤有较高的检测价值。
Objective To study the application of magnetic resonance T2 -mapping and diffusion weighted imaging（DWI）in diagnosis of early cartilage degeneration of the knee joint.Methods 56 patients with clinical intends to diagnosis of early osteoarthritis of the knee were set as observation group,another 56 healthy volunteers were selected as healthy control group.The subjects of the two groups were given knee MRI T2 mapping and DWI,the T2 acquisition value and ADC value of the two groups were analyzed and compared.Results In the observation group, the side of the femoral （37.18 ±4.09）,lateral tibial （32.16 ±2.75）and hip （34.56 ±4.21）were significantly lower than those in the healthy control group[femoral side （49.87 ±5.02）,tibial side （47.34 ±5.01）,hip surface （51.23 ±5.19）]（t =20.16,18.36,23.65,all P 〈0.05）.Conclusion Magnetic resonance T2 -mapping and DWI imaging can be found in the early knee cartilage degeneration,can lead to the rise of T2 and ADC value,so there is no cartilage damage to the cartilage damage.
