[MR tomography in glioblastomas and cerebral metastases].

36 Patients with glioblastomas (17 cases) and cerebral metastases (19 cases) were investigated by MRI. The typical signal behavior at different acquisition parameters (T1-, T1/T2-, Rho- and Rho/T2-weighted) was analysed using an interlaced triple sequence. In most cases the NMR-tissue parameter T1, T2 and proton-density (Rho) were determined to evaluate the potentials for tissue characterisation. The results of unenhanced vs. enhanced scans (MRI plus Gd-DTPA, CT) were analysed.
