The knees of 20 patients with evidence of meniscal tears were examined via high-resolution computed tomography (HRCT); 10 of these were studied by MRI. The HRCT study was performed directly after double-contrast arthrography (AG). For comparison with HRCT, slice orientation for MRI examination was in transverse view; gradient echo sequences using the FISP technique were applied instead of spin echo sequences. All results were correlated to the arthroscopy (AS) findings. In 95% of the cases AG and AS results agreed, HRCT/AS in 85% and MRI/AS in 70%. In certain cases HRCT provided additional information which influenced appropriate surgical treatment. MRI is a noninvasive nonionising method but gives a less exact documentation of the lesion than AG and HRCT. The gradient echo mode is superior to the SE mode in respect of outlining meniscal structures, at least in transverse view.
对20例有半月板撕裂证据的患者的膝关节进行了高分辨率计算机断层扫描（HRCT）检查；其中10例还进行了磁共振成像（MRI）研究。HRCT研究在双对比关节造影（AG）后立即进行。为了与HRCT进行比较，MRI检查的切片方向为横断位；采用FISP技术的梯度回波序列而非自旋回波序列。所有结果均与关节镜检查（AS）结果相关。在95%的病例中，AG和AS结果一致，HRCT/AS一致率为85%，MRI/AS一致率为70%。在某些情况下，HRCT提供了影响适当手术治疗的额外信息。MRI是一种非侵入性、非电离的方法，但对病变的记录不如AG和HRCT精确。至少在横断位上，梯度回波模式在勾勒半月板结构方面优于自旋回波模式。
