In chick embryos of an age of incubation of 5-14 days, the physiological development of the circulation and the morphological differentiation of the arterial system were studied by intravital and postmortal angiography. For the examinations of the living embryos, a special radiographic and injection technique had to be developed. The contrast medium was… (More)
Twenty patients with Echinococcus cysticus and 15 with E. alveolaris were studied. Selective upper abdominal angiographies, performed in most of these cases, were reviewed retrospectively for typical angiographic changes. In a large percentage, E. cysticus demonstrated typical cystic and expansive signs; atypical vessels were rarely seen. How the "rim sign"… (More)
In 33 patients (18 cystic echinococci, 15 alveolar) both methods produced the following findings which could be correlated with the pathological results: single or multi-centric lesions, sharp or indefinite demarkation and abnormalities in the shape and size of the liver. The sonographic findings were analysed with respect to the echo characteristics,… (More)
Evulsion fractures of the anterior inferior iliac spine in adults usually are the result of sudden contraction of the rectus femoris muscle during sporting activities, particularly football. In children, before fusion of the apophysis, there may be an apophyseolysis. This may result in a chondropathy because of abnormal development of the frequently… (More)
The introduction of the third and fourth generation of CT scanners (scan times of 1 to 20 seconds) has brought about a change in the choice of methods for investigating suspected suprarenal disease. The excellent spacial resolution of CT scans permits accurate evaluation of minor changes in the gland. As a result, it is often possible to avoid invasive… (More)
The clinical, pathological and radiological features and the differential diagnosis of the very rare condition of non-traumatic myositis ossificans circumscripta are illustrated by one patient. The characteristic radiological appearances make a correct diagnosis of this localised, non-malignant process possible.
A method for examination of the upper abdomen with a combination of real-time and stored B-mode technique is described. Some pathological findings are demonstrated. The combination of the methods considers the mechanical-technical advantages of these two apparatus. The complementary use can enhance the diagnostic accuracy.
