[Dynamic MRT after Gd-DTPA administration in kidney transplants: the susceptibility and T2 effects].

35 kidney transplanted patients (15 without pathological findings and 20 with histologically proven chronic rejection) were investigated with a combination of dynamic MR and bolus application of Gd-DTPA. The occurrence of susceptibility artifacts and T2 effects at the junction between papilla and renal calix were analysed. There are two groups of patients. The first one shows only artifacts due to susceptibility. The second group indicates the so-called "dark ring pattern" (susceptibility artifacts and T2 effects). These effects are discussed in terms of their dependence on concentration and their dependence on the degree of transplant malfunction. The appearance of "dark-ring patterns" and of susceptibility artifacts indicate the functional status of the glomerular filters.

[Experimental determination of weighting functions in magnetic resonance tomography].

Weighting functions are defined and calculated for the pulse sequences spin-echo and inversion recovery. These weighting functions make possible a qualitative discussion of the term "weighting" in MR imaging. Furthermore, a new method has been developed to determine weighting functions experimentally. A comparison between the results obtained and the theoretical predictions shows a sufficiently good agreement. This method can also be applied with other pulse sequences.
