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)
Because of its complicated embryological development, the anatomy of the renal veins shows extensive variability. A full understanding of the potential anatomical variations is imperative for retroperitoneal operations. Based on 4,520 retroperitoneal computerized tomography scans, anatomical studies of autopsy material of 354 unselected cases and(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)
BACKGROUND The aim of this study was to determine the value of routinely performed preoperative magnetic resonance cholangiography (MRC) in detecting common bile duct (CBD) stones in patients stated to undergo elective laparoscopic cholecystectomy. In addition, we used MRC to investigate possible variants of the cystic duct. METHODS Magnetic resonance(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)
We examined 82 patients 12 to 43 (mean 22) months after renal calculi had been removed by ultrasonic lithotripsy. Recurrence was noted in 2 patients but this correlated to the previous stone-forming rate. Smaller fragments that had remained in 9 patients were passed in 2, removed percutaneously in 2 and unchanged in the remainder. There was no evidence of(More)
The aims of this study were to evaluate the effectiveness of magnetic resonance cholangiography (MRC) in diagnosing patients with cholestasis and to compare these results to those obtained with endoscopic retrograde cholangiopancreaticography(ERCP). From January 1996 to December 1998 a total of 85 consecutive patients who were candidates for ERCP because of(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)
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)
