[Rapid and high-resolution 3D-imaging in MR tomographic diagnosis of diseases of the knee joint].
A new technique was developed for MR imaging of diseases of the knee joint to shorten the time required for examination. The acquisition of an isotropic 3D-dataset using a FLASH- or a FISP-sequence is the base for secondary reconstructions of planar high-resolution images (spatial resolution less than or equal to 1 mm) in free orientations. Acquisition time of the 3D-dataset is 16 minutes, additional one up to five minutes are needed for image calculation. The method can image structures of the knee joint such as the cartilage, the menisci or the ligament. The advantage of the decreased examination time of about 30 minutes has been proved, but further comparative clinical studies are needed to establish the diagnostic equivalence of this method and conventional techniques.
