OBJECTIVE To evaluate the findings in MRI-studies of the knee in recreational long-distance runners after competition and to assess the reversibility of the findings. DESIGN AND PATIENTS Eight recreational long-distance runners underwent MRI studies of the knee before, immediately after and 6-8 weeks after taking part in the Vienna City Marathon. The(More)
Neuromyelitis optica (NMO) is characterised by a particular pattern of the optic nerves and the spinal cord. Long-term MRI follow-up studies of spinal NMO lesions are rare, or limited by short observation periods. In nine patients with definite NMO or recurrent longitudinally extensive transverse myelitis (LETM) with NMO-IgG serum antibodies, repeated MRI(More)
OBJECTIVE The aim of the study was to evaluate long-term damage in the internal structures of the knee joints of recreational long-distance runners. MATERIALS AND METHODS Ten years after their participation in a baseline study concerning their knee joints, seven long-distance runners and one who had given up long-distance running were invited to(More)
Scope of this article is to give practical hints for the most common, typical and important topics of trauma radiology in children to those radiologists who are not exclusively occupied with paediatric imaging. Due to the increased radiation sensitivity of children compared with adults balancing radiation protection and necessary image quality is of utmost(More)
PACS development has now reached a stage where it can clearly be stated that the technology for storage, networking and display in a fully digital environment is available. This is reflected by an already large and rapidly increasing number of PACS installations in USA, Western Europe and Japan. Such installations consist of a great variety of information(More)
Accuracy of MRI reports is taken for granted. In this paper the inter-observer reliability in the interpretation of meniscal lesions, degree of chondropathy, and integrity of the ACL was analyzed while taking the radiologist's experience and field strength into account. Fifty-two MRI studies of knees were interpreted by 11 radiologists independently.(More)
BACKGROUND The prevalence of clinically silent intracranial tumors in specific populations is poorly researched. It is known that, in advanced age groups, the number of clinically manifest meningiomas constitute a small proportion of the actual number of cases. The goals of the current study were to determine the frequency of asymptomatic patients with(More)
The etiology of white matter hyperintensities (WMH) seen on T2-weighted cranial magnetic resonance images is a matter of debate. We investigated deep and periventricular WMH in the brains of a community-based cohort of 532 subjects aged 75-76 years. The objective of this study was to determine whether WMH at age of 75 years were associated rather with(More)
OBJECTIVE Pre- and postnatal pyelectasis detected by sonographic screening is of questionable pathologic importance. Therefore, we defined the natural course and diagnostic value of renal pelvis diameter (RPD) during fetal life and the neonatal period as such dilatation was revealed on routine sonography. MATERIALS AND METHODS Routine sonography in(More)
