This prospective double-blind study was designed to evaluate the capability of magnetic resonance imaging to serve as a diagnostic tool in patients who have a clinically suspected disorder of the meniscus. The imaging studies provided a diagnostic accuracy of 72 per cent, a sensitivity of 88 per cent, and a specificity of 57 per cent. The positive and(More)
The sectional anatomy of the pelvic floor was studied in plastinated sections of adult pelves by computed tomography and by magnetic resonance imaging. In sectional anatomy, the levator ani is composed of three portions that can be clearly distinguished by their planes of cleavage and by the course of their fiber bundles. No muscular connections are found(More)
The sectional anatomy of the pelvic connective tissue was studied in plastinated sections of fetal and adult pelves, by computed tomography and by magnetic resonance imaging. The comparative study of the different specimens shows that the pelvic connective tissue consists of three compartments: a presacral compartment, a perirectal compartment, and a(More)
An 18-year-old man suffered from acute Sydenham chorea appearing coincidently with β-haemolytic streptococcal throat infection. Imaging techniques documented lesions of basal ganglia and substantia nigra. In the early course of the disease vascular lesions may be important pathogenetic mechanisms of this acquired movement disorder.
In a prospective double-blind study, the capability of magnetic resonance imaging (MRI) and arthroscopy in the detection and grading of meniscal degenerations is evaluated by correlating MRI findings and arthroscopic diagnoses with a histologic grading model. In 82.8% of our results, grading based on MRI studies corresponded with the histologic grading(More)
Ameloblastomas of the jaw are rare epithelial tumors. They have to be differentiated from simple cysts and malignant tumors. If incompletely excised they have a high recurrence rate so that radical surgery from the beginning must be the therapy of choice. Exact preoperative diagnosis of the tumor and its possible spread into the infratemporal fossa or the(More)
To study left ventricular morphological and functional changes in the first six months after acute myocardial infarction, 37 patients (28 male, 9 female, age 42-78 years) underwent cardiac Cine-MRT 1 week, 4 weeks and 6 months after their first myocardial infarction. MR-tomograms were oriented to left ventricular true long and short axis. For comparison,(More)

For the visualization of the uterine cavity hysterography (HS) is an established procedure. Hysterosonography (HS) is a new imaging modality. In an in vitro study the features of HS have been compared to those of HG. The results of both methods were verified by macroscopic and microscopic specimen. HS is superior to HG in determining the diameter of the(More)
A 32-year-old man had for about four months been suffering from discomfort in the left thorax unrelated to exertion. Coronary angiography revealed a haemangioma, 40 mm in diameter, which arose from the anterior descending branch of the left coronary artery with a connecting fistula to the main pulmonary artery. The tumour could not be demonstrated by either(More)
