CT perfusion as a useful tool in the evaluation of leuko-araiosis
BACKGROUND Leuko-araiosis (LA) and dementia are common geriatric conditions but their pathogenesis and clinical significance are not completely understood. An evaluation of CT perfusion (CTP) in both these conditions can further enhance the understanding of these diseases. METHODS Twenty-one patients with LA and 21 age-matched controls were studied with CTP and assessed for their cognitive fu...
متن کاملClinical features of leuko-araiosis.
OBJECTIVE To study the clinical features of leuko-araiosis. METHODS Age matched groups of patients with a CT finding of pure leukoaraiosis (n = 26) and a control group with a normal CT finding (n = 26) were formed (mean ages 78.6 (SD 3.3) v 76.5 (SD 4.6) years; NS). RESULTS Dementia, vascular dementia, central brain atrophy on CT, disability in activities of daily living and instrumental ac...
متن کاملCorrelations of leuko-araiosis with cerebral atrophy and perfusion in elderly normal subjects and demented patients.
CT images of leuko-araiosis in brain slices were quantified according to volumes of reduced Hounsfield units in frontal periventricular white matter in groups of elderly patients with multi-infarct dementia (MID, n = 23) and dementia of the Alzheimer type (DAT, n = 16). Volumes of leuko-araiosis, estimates of atrophic cerebral tissue, and local cerebral perfusion utilising inhalation of xenon g...

15 صفحه اولHistogram analysis- a useful tool for tissue characterization in brain CT
Introduction: Pixel value in computed tomography (CT) gives the average linear attenuation coefficient of the scanned material in the path of the x-ray beam, being normalized to that of water. It is known that attenuation coefficient or HU value is a function of the chemical characteristic of the material and of the x-ray energy. The CT image shows the HU value by a shade of gr...
