The purpose of this study was to examine the accuracy of MR imaging of the healthy and the arthrotically altered articular hip cartilage with in vivo and in vitro separation of femoral head cartilage and acetabular cartilage. ⋯ Using these MR-examinations, an improved imaging of early stage arthrotic cartilage defects is possible, and the status of the arthrotic hip cartilage with regard to intertrochanteric osteotomy can also be assessed.

To describe the MR imaging findings in patients with lateral patellar dislocation. ⋯ Hemarthrosis, lateral femoral and medial patellar contusion, and retinacular disruption are typical findings after lateral patellar dislocation. A careful search for free osteochondral fragments is mandatory as it influences the indication and performance of arthroscopic surgery.

Comparative Study
[Static and dynamic MR tomography of the pancreas: contrast media kinetics of the normal pancreatic parenchyma in pancreatic carcinoma and chronic pancreatitis].
We aimed both at improving image quality and diagnostic value of pancreatic MRI by using fast multislice imaging techniques and at demonstrating normal and pathologic signal enhancement in the pancreas after i.v. gadopentate-dimeglumine. ⋯ MR imaging with fast T2-w SE and T1-w SE sequences provides excellent visualisation of the pancreas and adequate conspicuity of pancreatic adenocarcinoma. Following i.v. Gd-DTPA significant enhancement of tumour/parenchyma contrast is found.

Comparative Study
[High-resolution magnetic resonance tomography (HR-MRT) of the pleura and thoracic wall: normal findings and pathological changes].
To determine the value of high-resolution MRI in pleural and chest wall diseases, the normal and pathologic costal pleura and adjacent chest wall between paravertebral and the axillary region were examined with contrast enhanced high-resolution T1-weighted MRI images using a surface coil. ⋯ HR-MRI images improved non-invasive evaluation of pleural and chest wall diseases, and allowed for differentiation of benign and malignant changes.

Comparative Study
[Perimesencephalic subarachnoid hemorrhage: clinical and computer tomography aspects].
The blood distribution on CCT and the prognosis of patients with nonaneurysmal subarachnoidal haemorrhage were retrospectively studied and compared to a patient group with aneurysmal haemorrhage. ⋯ The perimesencephalic pattern is frequently found in patients with nonaneurysmal subarachnoidal haemorrhage, the prognosis of these patients is excellent. Rarely is the perimesencephalic haemorrhage caused by a ruptured aneurysm. It needs thorough angiographic evaluation.
