| Research Abstract |
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.
