New MR Delineation of Articular Cartilage

本研究的目的是建立关节软骨高分辨率图像的MRI描绘方法。我们介绍了两种创新的成像工具，平行成像和显微成像。并行成像（SENSE方法）能够在20分钟内获得160多张切片，这是之前方法的两倍。交叉、半月板病理及软骨病变的诊断结果令人满意。显微镜提供了高分辨率的图像，平面内分辨率为0.1 mm，并描绘了关节软骨的细微不规则，特别是在膝关节内侧。这两种方法将保证软骨的正常和病理情况，这是很难用常规成像描绘。

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.
