MR imaging is established as a useful diagnostic method for the examination of meniscal disorders due to excellent spatial resolution and high soft tissue contrast. Instead of 2D spin echo sequences, we use 3D data acquisition with 1 mm slice thickness to further improve spatial resolution. In diagnostic routine, the use of fast pulse sequences is necessary, with the advantage of increased contrast between the low signal meniscus and the high signal intensity of the adjacent articular cartilage. Rapid processing allows image reconstruction in various planes. The entire examination data acquisition to image reconstruction requires 15-20 min. The 3D data aquisition helps to avoid potentials pitfalls, e.g., partial volume effects. The use of thin slices and fast sequences improves the sensitivity of MRI in the evaluation of small meniscal lesions and shorters the imaging time. Verf.-Referat
