Method and apparatus for constructing an assessment of an ignition of a joint, for determining a proteoglycans - portion of the joint, and to create an evaluation of a osteoarthritis of the joint as well as correspondingly configured magnetic resonance system

摘要

For a predetermined area within a body of a patient, by means of a magnetic resonance system generates a three-dimensional mr - image data set (s5), wherein in the region of at least partially, a joint is. For a plurality of different specific layers is in each case automatically from the three-dimensional mr - image data set a two-dimensional mr - image is calculated (s6, s7). For each layer, a thickness of a predetermined fabric, which, in which the layer corresponding two-dimensional mr - image is imaged, is determined (s8), as a result of which automatically as a function of the specific thicknesses an evaluation of a joint inflammation is determined (s10). In addition, in particular automatically, a further layer in the region is determined (s12) and after injection of a contrast agent (s4) for this layer a two-dimensional t1 - weighted mr - image (s13), as a result of which automatically a proteoglycans - proportion is determined (s16). From the evaluation of the joint inflammation and the proteoglycans - proportion can then a reproducible evaluation of a osteoarthritis of the joint can be carried out (s21, s22).
