Interexaminer difference in infarct volume measurements on MRI: a source of variance in stroke research.
BACKGROUND AND PURPOSE The measurement of ischemic lesion volume on diffusion- (DWI) and perfusion-weighted MRI (PWI) is examiner dependent. We sought to quantify the variance imposed by measurement error in DWI and PWI lesion volume measurements in ischemic stroke. METHODS Fifty-eight consecutive patients with DWI and PWI within 12 hours of symptom onset and follow-up MRI on >or= day-5 were ...
متن کاملReproducibility of measurements of cerebral infarct volume on CT scans.
BACKGROUND AND PURPOSE Infarct volume is increasingly used as an outcome measure in clinical trials of therapies for acute ischemic stroke. We tested which of 5 different methods to measure infarct size or volume on CT scans has the highest reproducibility. METHODS Infarct volume and total intracranial volume were measured with Leica Q500 MCP image analysis software, or with a caliper, on 38 ...
متن کاملcomparison of prostate and bladder volume measurements from mri and pre- and post-mri ultrasound images
background : safe dose escalation is highly desirable in radiotherapy for prostate cancer. prostate displacement due to bladder filling can be significant, so improved targeting of the prostate by ultrasound imaging potentially allows for a reduction in the target margin and consequently less toxicity. this study estimates the accuracy of ultrasound for prostate and bladder volume measurements ...
متن کاملMRI Brain Volume Measurements in Infantile Neuronal Ceroid Lipofuscinosis.
BACKGROUND AND PURPOSE Infantile neuronal ceroid lipofuscinosis is a devastating neurodegenerative storage disease caused by palmitoyl-protein thioesterase 1 deficiency, which impairs degradation of palmitoylated proteins (constituents of ceroid) by lysosomal hydrolases. Consequent lysosomal ceroid accumulation leads to neuronal injury, resulting in rapid neurodegeneration and childhood death. ...
متن کاملCorrelation Between Cannabidiol-Induced Reduction of Infarct Volume and Inflammatory Factors Expression in Ischemic Stroke Model
Introduction: Recent studies demonstrated that cannabidiol had neuroprotective property. Thereis some evidence about effective role of cannabidiol in reducing ischemic damages. It has been reported that infarct size is influenced by various factors after MCAO, including inflammatory factors. The aim of the present study was to evaluate the effect of cannabidiol on infarction volume and correlat...
