[Results of follow-up after surgical treatment of Perthes disease: comparison of roentgenologic and and magnetic resonance tomography examination].

Twenty patients treated by surgery for Perthes' disease were studied between 4 and 9 years postoperatively. In the clinical investigation eight patients complained of persistent stress-induced pain. In nine patients flexion, extension, ab- and adduction of the hip joint was limited.

[Magnetic resonance tomography diagnosis of the posterior chamber lens].

Intraocular lenses were investigated by MRI to obtain information about the quality of this method. In experimental studies, seven lenses of between 0 and 30 diopters were visualized. By MRI it was possible to differentiate the various diameters of lenses.

[Magnetic resonance tomography of new rupture of the anterior talofibular ligament].

Twenty acutely traumatised patients with a rupture of the anterior talofibular ligament were studied by MRI. The results of 3D-studies were correlated with conventional stress x-ray studies. The ruptured ligament was directly visualised in all cases as a thickened structure of high signal intensity.

[Gadolinium-DTPA enhanced MRT in the evaluation of the healing of autologous patellar ligament transplants for anterior cruciate ligament reconstruction].

Eighteen patients with autologous patellar tendon transplant for reconstruction of the anterior cruciate ligament were examined postoperatively. The time between operation and MR study was up to 3 weeks in ten patients, between 3 and 35 weeks in three patients and more than 35 weeks in five patients. In all patients, Gd-DTPA enhancement on the surface of the ligamentous transplant was visualized.

[Magnetic resonance tomographic diagnosis of internal lesions of the shoulder following luxation. A comparison with arthroscopic findings].

Fifteen patients with a recurrent dislocation of the glenohumeral joint were preoperatively investigated by MRI. We created a special protocol with axial T1-, T2-, proton-density- and sagittal T1-weighted images. MRI findings such as defects of the glenoid labrum and Hill-Sachs compression fractures proved to be correct during surgery.
