We read with interest the article ‘Pancreatic Mucinous Cystic Neoplasm Size Using CT Volumetry, Spherical and ellipsoid formulas: Validation Study’ by Chalian et al. [1] published in the January 2014 edition of Journal of the Pancreas .JOP (online). We commend the authors for their valuable contributions towards establishing the accuracy and reproducibility of CT volumetry for pancreatic cysts....
Although some older adults experiencing memory problems have been shown to benefit from cognitive training, evidence regarding who will improve from this type of intervention is lacking. Automated hippocampal volumetry might be used to foresee treatment outcomes. We hypothesized that larger hippocampal volumes are associated with greater memory performance changes following training, and that e...

OBJECTIVE The purpose of this study was to investigate the accuracy and reproducibility of results acquired with computer-aided volumetry software during MDCT of pulmonary nodules exhibiting ground-glass opacity. MATERIALS AND METHODS To evaluate the accuracy of computer-aided volumetry software, we performed thin-section helical CT of a chest phantom that included simulated 3-, 5-, 8-, 10-, ...
We developed a miniaturized conductance catheter for in situ rat left ventricular (LV) volumetry. After the validation study of the conductance volumetry in 11 rats, we characterized the end-systolic pressure-volume relationship (ESPVR) in 24 sinoaortic-denervated, vagotomized and urethan-anesthetized rats. Stroke volume (SV) measured with the conductance catheter correlated closely with that m...
BACKGROUND The promise of Alzheimer's disease biomarkers has led to their incorporation in new diagnostic criteria and in therapeutic trials; however, significant barriers exist to widespread use. Chief among these is the lack of internationally accepted standards for quantitative metrics. Hippocampal volumetry is the most widely studied quantitative magnetic resonance imaging measure in Alzhei...
Background: Cerebral edema (CE) and intracranial hypertension (IHT) are complications of numerous neurological pathologies. However, the study CE noninvasive methods to predict IHT remains rudimentary. This aims identify in traumatic brain injury (TBI) patients relationship between volume lateral ventricles parameters pressure waveform (nICPW). Methods: is an analytical, descriptive, cross-sect...
PURPOSE To provide a more detailed investigation of hippocampal subfields using 7T magnetic resonance imaging (MRI) for the identification of hippocampal sclerosis in temporal lobe epilepsy (TLE). MATERIALS AND METHODS Patients (n = 13) with drug-resistant TLE previously identified by conventional imaging as having hippocampal sclerosis (HS) or not (nine without HS, four HS) and 20 age-matche...
