The objective of this study was to evaluate dietary fecal tagging (FT) as a cleansing method prior to CT colonography (CTC) in patients with incomplete conventional colonoscopy (CC). After written informed consent was obtained, 24 patients had standard colonoscopic preparation (ScCl), and 25 patients had FT as cleansing method. Segmental distention, fluid(More)
PURPOSE The aim of this study was to compare CT findings of adrenal incidentalomas with a definitive histological diagnosis in order to establish CT features characteristic for individual types of lesions. PATIENTS AND METHODS The retrospective study comprised of patients with adrenal lesions detected on abdominal CT. The patients with these incidental(More)
BACKGROUND AND PURPOSE Gadobenate dimeglumine has proved advantageous compared with other gadolinium-based contrast agents for contrast-enhanced brain MR imaging. Gadobutrol is a more highly concentrated agent (1.0 mol/L). This study intraindividually compared 0.1-mmol/kg doses of these agents for qualitative and quantitative evaluation of brain tumors. (More)
OBJECTIVES Intravenous thrombolysis (IVT) is considered an effective treatment for acute ischemic stroke (IS). However, not all treated patients may achieve good outcome. The aim was to evaluate whether the initial NIHSS and DWI infarct volume could be the predictors for good outcome after IVT. PATIENTS AND METHODS The set of 125 patients with consecutive(More)
A Multi-Start Spatio-Temporal (MSST) multidipole localization algorithm was used to study sources on the anterior and posterior banks of the central sulcus localized from early somatosensory magnetoencephalography (MEG) responses. Electrical stimulation was applied to the right and left median nerves of 8 normal subjects. Two sources, one on the anterior(More)
The authors present the results of 9-year work with 3D CT in orthopaedics and musculoskeletal traumatology. In the years 1990-1998, the method was used in the examination of 59 patients (27 males, 20 females, and 12 children). The place of 3D CT in clarifying areas of complex musculoskeletal anatomy for operative treatment is discussed and presented as a(More)
A 24-year-old man with hereditary multiple exostoses had numbness of the lower extremities and difficulty walking. CT displayed a calcified extradural mass lesion within the spinal canal at T-8 causing cord compression. MR imaging showed it to be contiguous with the upper endplate of T-8, suggesting the diagnosis of osteochondroma, a rare cause of cord(More)
AIMS Optic nerve sheath diameter (ONSD) enlargement is detectable in patients with increased intracranial pressure. The aim was to detect an enlargement of the ONSD using optic nerve sonography in patients with acute intracerebral haemorrhage (ICH) within 6 h of the onset of symptoms. METHODS Thirty-one acute ICH patients, 15 age-matched acute ischaemic(More)
AIM To determine the frequency of extraocular rectus muscle involvement in patients with thyroid-associated orbitopathy (TAO). MATERIALS AND METHODS A total of 154 orbits of 77 adult patients (53 women and 24 men) with TAO aged from 18 to 81 years (median 49 years) were investigated. Only patients with clear signs of TAO and confirmed thyroid disease who(More)
