Preface better recognized, if this overlapping of different In recent years microsurgical strategies have been mostly assisted by magnetic resonance measurements, structures is known. in which many morphological details surrounding the This book is divided in two parts. The general part pathological lesions can be better seen than in CT. So demonstrates comparisons of NMR and anatomical dissections. The special part considers anatomical it seems important to compare NMR (MRI, MR)­ findings with anatomical dissections of the brain and problems for complicated operations in the depth of skull. In sagittal slices, most important slices close to the brain. Cornu inf., basal ganglia and cisterns, CT reconstruc­ These special dissections have to regard brain struc­ tures more than the vessels, which are well known. In tions are not so instructive as NMR. Anatomical coronal transections are used in neuropathology, but some cases brain dissections may be compared with except in CT reconstructions, coronal projections skull dissections. The shifts of brain stuctures by tumors or other space­ were not considered in neuroradiological findings as occupying lesions are not considered here. They will they are now in NMR. Horizontal slices are well known from CT, but important details, e. g. the area be demonstrated in the next volume with description between Chiasma, quadrigeminal plate, Fornices and of microsurgical operations based on NMR-findings.
