title: [Diffusion tensor imaging and sequel of brain injury].
abstract: By observing the magnitude and direction of thermal motion of water molecules, diffusion tensor imaging (DTI) allows the study of the internal structure and disturbances of the white matter tracts. For instance in neurosurgery, the relation of the corticospinal tract to the tumor to be operated can be defined in this manner when planning the operation. It is hoped that DTI will be beneficial for patients who are not recovering from brain injury in an expected manner, although conventional imaging methods do not reveal any brain damage. Indeed, DTI is able to distinguish brain-damaged patients from healthy controls also in cases of a normal MRI finding.
