We have been able to display the hyaline hip joint cartilage clearly and with high signal strength in the magnetic resonance image with a gradient echo sequence with 2 different fresh hip specimens from corpses and with 10 healthy test subjects (5 m, 5 f). The chemical shift artifact at the bone-cartilage boundary could be clearly reduced by optimizing the geometrical scanning parameters. A comparison between the cartilage thickness at the head of the femur measured on the anatomical specimen with the thickness measured in the magnetic resonance tomogram showed a good correlation on suitable selection of the read-out gradient. The hyaline cartilage at the head of the femur could be differentiated from the acetabular cartilage in the region of the loading zone by magnetic resonance tomography in all 10 test subjects.
我们能够在磁共振图像中，使用梯度回波序列，清晰地显示透明的髋关节软骨，且信号强度高。我们使用了来自尸体的2个不同的新鲜髋关节标本以及10名健康受试者（5名男性，5名女性）。通过优化几何扫描参数，可明显减少骨-软骨边界处的化学位移伪影。在解剖标本上测量的股骨头部软骨厚度与在磁共振断层图像中测量的厚度之间进行比较，结果表明，在适当选择读出梯度时，二者具有良好的相关性。在所有10名受试者中，通过磁共振断层扫描，在负重区可区分股骨头部的透明软骨和髋臼软骨。
