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)
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 incidence of clinically silent meningiomas in 75-year-old individuals was determined five years ago in the Vienna Transdanube Ageing Study (VITA). At the time a watch-and-wait approach was recommended in cases of incidentally discovered meningiomas. METHODS 420 out of the initial cohort of 532 test persons underwent control investigations(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)
The aim of this study is an evaluation of the use of (semi-) automatic software solutions for the derivation of crown surface models and further forest information like vegetation height and vertical stand structure. It gives an overview of the up-to-date reachable accuracies of crown surface models and vegetation heights from traditional aerial images in(More)
