The objective of this study was to evaluate the sensitivity of ultrashort echo time (uTE) sequence for visualisation of calcified deep layers of articular cartilage. MRI with a uTE sequence was performed on five healthy volunteers. Signals from the calcified deep layers of the articular knee cartilage were evaluated on uTE subtraction images and computed tomography images. The calcified deep layers of the articular cartilage changed from having a low to a high signal when imaged with a uTE sequence. The reported uTE sequence was effective in imaging the deep layers of the knee cartilage.
本研究的目的是评估超短回波时间（uTE）序列对可视化关节软骨钙化深层的敏感性。对五名健康志愿者进行了uTE序列的磁共振成像（MRI）检查。在uTE减影图像和计算机断层扫描图像上评估膝关节软骨钙化深层的信号。当用uTE序列成像时，关节软骨钙化深层的信号从低信号变为高信号。所报道的uTE序列在膝关节软骨深层成像方面是有效的。
