The purpose of this study was to establish the MRI delineation methods for high-resolution images of the articular cartilage. We introduced two innovative imaging tools, the parallel imaging and the microscopy imaging.The parallel imaging (SENSE method) enabled the acquisition to obtain over 160 slices within 20 minutes, which was double the performance of the previous method. Diagnostic results of the cruciate and meniscal pathologies as well as cartilage lesions were satisfactory.The microscopy provided high-resolution imagining with in-plane resolution of 0.1 mm and delineated subtle irregularities of the articular cartilage, especially in medial aspect of the knee joint. These two methods will promise the normal and pathological conditions of the cartilage, which was hardly delineated by using the conventional imaging.

本研究的目的是建立关节软骨高分辨率MRI图像的勾画方法。我们引入了两种创新的成像工具，并行成像和显微成像，并行成像（SENSE方法）使采集在20分钟内获得超过160个切片，这是以前方法性能的两倍。对膝关节软骨病变的诊断结果令人满意，显微镜提供了高分辨率图像，平面分辨率为0.1mm，并描绘了关节软骨的细微不规则性，尤其是在膝关节内侧。这两种方法将保证软骨的正常和病理状态，这是很难用常规成像描绘。
