Discriminant Analysis of Intracranial Volumetric Variables in Patients with Normal Pressure Hydrocephalus and Brain Atrophy.

A method was developed for the computerized volumetric assessment of the intracranial cerebrospinal fluid (CSF) distribution. The study involved 62 patients differentiated into two groups: with CSF resorption disorders (normal pressure hydrocephalus - 30 patients) and without CSF resorption disorders (various types of brain atrophy - 32 patients). The goal of the study was to ascertain whether the assessment, depending on the linear discriminant analysis of volumetric brain features, could be an effective tool differentiating the two groups.

Analysis of intracranial volume ratios by means of cerebrospinal fluid deployment indicators.

Introduction: Imaging studies make it possible not only to visualize the general structure of the brain but also to take precise measurements of brain tissue volume and the size of individual lobes and their structure. The aim of this study was to determine the ratio of cerebrospinal fluid (CSF) volume contained in the intracranial ventricular system to the brain tissue volume and the ratio of CSF volume in the subarachnoid space and basal cisterns to the brain tissue volume.

Material And Methods: The evaluation of volumetric measurements of computed tomographic (CT) images was undertaken on 23 male and female patients (average age 56.

[The usefulness of the evaluation of volumetric and posturographic parameters in the differential diagnosis of hydrocephalus].

Introduction: A variety of diagnostic methods in normal pressure hydrocephalus and brain atrophy, it testifies to the difficulties in contrast to both teams. Develop a safe diagnostic tool having comparable statistical accuracy of the infusion test results would be of great clinical significance. The chances of implementing such a procedure in clinical practice, it may be a combination of these syndromes in the functional assessment (Posturography) the assessment of morphological CNS (volumetric).

[Diffusion tensor imaging (DTI) in the differential diagnosis of normal pressure hydrocephalus and brain atrophy].

Unlabelled: Clinical symptomatology of idiopathic normal pressure hydrocephalus, due to its overlap with dementias and neurodegenerative brain disorders, makes diagnosis challenging. As the neurological deficits are reversible there is a need for prompt and reliable noninvasive testing. The aim was to try to use and introduction into clinical practice of new non-invasive method--diffusion tensor imaging (DTI-Diffusion Tensor Imaging) discriminating patients classified as normal pressure hydrocephalus and patients diagnosed with brain atrophy.
