BACKGROUND Both brain atrophy and decrease of perfusion are observed in dementive diseases. The aim of the study was to correlate the results of brain perfusion CT (pCT) and CT volumetry in patients with Alzheimer's disease (AD). MATERIAL/METHODS Forty-eight patients with AD (mean age of 71.3 years) underwent brain pCT and CT volumetry. The pCT was performed at the level of basal ganglia afte...

BACKGROUND Hippocampal atrophy is a well-known feature of Alzheimer's disease (AD), but sensitivity and specificity of hippocampal volumetry are limited. Neuropathological studies have shown that hippocampal subfields are differentially vulnerable to AD; hippocampal subfield volumetry may thus prove to be more accurate than global hippocampal volumetry to detect AD. METHODS CA1, subiculum and...

OBJECTIVES Central nervous system involvement is one important clinical aspect of myotonic dystrophy type 1 and 2 (DM1 and DM2). We assessed CNS involvement DM1 and DM2 by 3T MRI and correlated clinical and neuocognitive symptoms with brain volumetry and voxel-based morphometry (VBM). METHODS 12 patients with juvenile or classical DM1 and 16 adult DM2 patients underwent 3T MRI, a thorough neu...

Background
 Migraine was previously interpreted as “benign” disease since the major part of patients were asymptomatic between attacks and brain lesions are absent in primary headaches. Advances structural neuroimaging have changed this point view. Voxel-based-morphometry is an accurate technique to evaluate objectively damage. Our hypothesis that some clinical features migraine, aura atta...

MRI-based hippocampus volume, a core feasible biomarker of Alzheimer's disease (AD), is not yet widely used in clinical patient care, partly due to lack of validation of software tools for hippocampal volumetry that are compatible with routine workflow. Here, we evaluate fully-automated and computationally efficient hippocampal volumetry with FSL-FIRST for prediction of AD dementia (ADD) in sub...

There are very few reports on pancreatic volumetry using multidetector-row computed tomography (MDCT). In the present study, we performed pancreatic volumetry for 148 patients who had undergone pancreatectomy at this institution between June 2006 and May 2011 and for 50 patients who had undergone laparoscopic cholecystectomy (LC) for cholecystolithiasis with no choledocholithiasis between Janua...

BACKGROUND The purpose of this study was to test the stereology method using several grid sizes for measuring liver volume and to find which grid provides an accurate estimate of liver volume. MATERIALS AND METHODS Liver volume was measured by volumetry in 41 sets of liver MRI. MRI was performed before and after different weight-reducing regimens. Grids of 3, 4, 5, and 6 cm were used to measu...

CONTEXT The treatment of edema after a knee injury is usually 1 of the main objectives during rehabilitation. To assess the success of treatment, 2 methods are commonly used in clinical practice: volumetry and perimetry. OBJECTIVE To investigate the intra- and interassessor reliability of volumetry and perimetry to assess knee volume. DESIGN Cross-sectional. SETTING Laboratory. PARTICIP...
