3D CAIPIRINHA accelerated SPACE is a newly developed technic that can achieve faster acquisition and high resolution isotropic 3D imaging of the knee. However, its clinical diagnostic performance in knee joint hasn’t been proved yet. In this study, we compared the clinical diagnostic performance of 3D CAIPIRINHA accelerated SPACE and the conventional routine knee MRI in patients with knee injuries. We found that 3D CAIPIRINHA accelerated SPACE was able to detect more cartilage lesions and meniscus tear than the conventional 2D knee protocol. Whereas, the clinical diagnostic performance of the other lesions, such as bone marrow edema and ligaments tear were similar of the two protocols.
