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)
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)
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)
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)
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)
The aim of the study was to evaluate long-term damage in the internal structures of the knee joints of recreational long-distance runners. 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 participate in a repeat magnetic resonance(More)
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. Magnetic resonance cholangiography was(More)
The aim of this study was to evaluate feasibility of reporting brain CT examinations on liquid crystal display (LCD) flat-screen monitors vs state-of-the-art cathode-ray-tube (CRT) monitors. Ninety-five brain CT examinations of 95 patients were displayed on Picture archiving and communications system (PACS) workstations equipped either with a dedicated(More)
Preoperative knowledge of full-thickness rotator cuff tear size is important in counseling patients because tear size affects the choice of surgical techniques and the functional outcome of surgery. Twenty-six shoulders of twenty-five consecutive patients were included in a prospective study that compared the preoperative accuracy of magnetic resonance(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)
