The aim of the present study was to further explore the neuronal mechanisms of face processing in healthy subjects which may help to understand the difficulties experienced by prosopagnosia subjects. A further goal was to compare face specific activation patterns in the right and left occipital face area (OFA) and fusiform face area (FFA) for famous faces,(More)
Early signs of brain infarction can be detected by modern CCT technology even within the first 6 h after stroke. Little is known about the prognostic significance of early infarction signs in CCT. We prospectively evaluated clinical and CCT findings of 95 consecutive patients with an acute ischemia in the territory of the middle cerebral artery. All(More)
PURPOSE To investigate the feasibility of using magnetic resonance venography (MRV) to detect pelvic venous congestion (PVC). METHODS A prospective study of 23 female patients with signs and symptoms of PVC, who underwent duplex sonography, MRV and phlebography (P). Examinations were interpreted in a blinded fashion. Visualization of venous anatomy,(More)
BACKGROUND AND PURPOSE In amyotrophic lateral sclerosis (ALS), fiber degeneration within the corticospinal tract (CST) can be quantified by diffusion tensor imaging (DTI) as an indirect marker of upper motor neuron involvement. A new method of measuring quantitative DTI parameters using a probabilistic mixture model for fiber tissue and background in the(More)
Based on 12 patients with posttraumatic erectile dysfunction due to pelvic fractures, ruptures of urethra and straddle-trauma, the diagnostic and therapeutic means in the management of erectile failure are discussed. The most frequent etiology encountered in posttraumatic erectile failure were combined arterial-neurogenic lesions followed by insufficiencies(More)
Patients with varicose veins who also had clinical and/or duplex ultrasound findings suspicious of pelvic venous incompetence (PVI) underwent selective retrograde catheter phlebography of the pelvic veins. One hundred and one patients (all female, mean age 49.3 years) underwent selective phlebography of the pelvic veins. In 68 cases (67.3%) a varicose vein(More)
Exposure to irradiation and radiation stress of the eye lens, thyroid and skin in high resolution computed tomography of the petrous bone are demonstrated by means of measurements conducted by the authors, and compared with results published to date. The radiation stress is less than the doses measured during conventional polytomography of the petrous bone.(More)
BACKGROUND Raynaud's phenomenon is a hallmark of progressive systemic sclerosis (SSc). While nailfold capillary changes are well known, morphological changes in larger arteries have less been focused on. OBJECTIVE AND METHODS In the study presented we examined how often in digital subtraction angiography organic changes of the arteries of the fingers,(More)
Only computed tomography (CT) is able to demonstrate ocular, orbital and peri-orbital soft tissues, calcification and bony structures directly and without superimposition of other tissues. 165 patients with tumours of the eye or orbit have been examined by CT and in 143 the diagnosis has been confirmed. The value of CT lies in its ability to demonstrate(More)
PURPOSE To present data on the MR imaging appearance of lumbar intraspinal juxtafacet cysts (JFC) and to assess the importance of additional CT arthrography. MATERIAL AND METHODS Twenty-eight patients (16 women, 12 men) with a mean age of 64 years (range: 43 - 82), who underwent MR imaging because of radicular pain or spinal claudication, were found to(More)
