[Further development of the diagnostic possibilities of MR tomography. Combination of 3D sequences with a rapid image processing system].
Using 3-D Fourier analysis, it is possible during MR tomography to provide isotropic data of large volumes, ie. uniform spatial resolution with a voxel size of 1 mm3. If one uses a gradient echo sequence with a picture matrix of 256 X 256 X 128 voxels, then examination time is less than 15 minutes. The information contained in this enormous amount of data can be evaluated by means of rapid image analysis. The advantages of this method have been demonstrated by three examples from the head and the spine.
