| Popis: | Thirty-five patients with suspected internal derangements of the knee were examined with conventional two-dimensional (2D) spin-echo magnetic resonance (MR) imaging techniques and a new rapid three-dimensional (3D) method called 3D FASTER (field echo acquisition with a short repetition time and echo reduction). A 9-minute 3D FASTER data acquisition achieves nearly isotropic voxels for the calculation of any desired image plane without a significant loss in image quality. Image contrast is optimized for visualization of knee anatomy in a single sequence. An image-processing workstation is used to speed the multiplanar image calculation and display for more efficient analysis of the complex 3D data set. The 3D FASTER images were superior or equal to 2D images (which took three times longer to acquire) in demonstrating meniscal tears, ligament tears, bone marrow disease, and osteochondral defects. The combined advantages of improved imaging capability and efficiency could make 3D FASTER imaging a routine MR method for knee imaging. |
