[Osteopoikilosis in magnetic resonance tomography (case report)].
A case report shows the differential diagnosis of osteopoikilosis ("spotted bones")--beside X-ray and scintigraphic results--in Magnetic Resonance Imaging (MRI).

[Magnetic resonance tomography of the craniocervical junction in chronic polyarthritis].
Magnetic resonance imaging and conventional radiographs and tomograms were correlated in 61 patients with chronic polyarthritis. Radiographs of the occipito-cervical junction only demonstrated bone lesions, erosions were detected on conventional tomograms. MRI was adequate for demonstration of bone abnormalities and soft tissue lesion and was especially suitable for detection of complications at the cervical spinal cord.

[Space-occupying lesions of the pineal region in magnetic resonance tomography].
Preoperative CT and MRI studies of 24 patients with space-occupying lesions of the pineal region were analysed. MRI demonstrated all 24 lesions, whereas CT could detect only 20 out of 24. MRI was superior to CT in assessment of size, localisation and relation to adjacent structures. No significant difference was found between CT and MRI in preoperative prediction of tumour histology.

Cine-MR in dissection of the thoracic aorta.
Magnetic resonance imaging (MRI) of the thoracic aorta, including cine-MRI, was performed in 25 patients suspected of having dissection of the thoracic aorta. MRI was correlated with echocardiography, CT and angiography. The sensitivity of MRI (100%) was most closely followed by CT and angiography (83% and 77% respectively). The specificity of MRI and angiography was equally good, at 100% each. MRI was able to demonstrate the intimal flap in all 9 cases of aortic dissection, and there were no false-positive results. Differentiation of thrombosis and slow flow was possible on proton density images, gradient echo images permitted detection of the entry and re-entry sites. The nature of the dissection was determinated correctly in 8 out of 9 cases. MRI is capable of providing all the relevant parameters necessary to decide appropriate treatment of dissecting aneurysms of the thoracic aorta.
