Abstract Background MRI is the method of choice in diagnosis MS as well monitoring disease activity. volumetry used to assess whole or regional brain volume loss which reflects neurodegenerative aspect and plays an important role all stages disease. The aim this work study evaluation cerebellum stem RRMS patients its correlation with neurological disability score number relapses. Results Volume...
Motor impairment after stroke is related to the integrity of the corticospinal tract (CST). However, considerable variability in motor impairment remains unexplained. To increase the accuracy in evaluating long-term motor function after ischemic stroke, we tested the hypothesis that combining diffusion tensor imaging (DTI) and gray matter (GM) volumetry can better characterize long-term motor d...
BACKGROUND AND PURPOSE Quantitative MR imaging techniques are gaining interest as methods of reducing acquisition times while additionally providing robust measurements. This study aimed to implement a synthetic MR imaging method on a new scanner type and to compare its diagnostic accuracy and volumetry with conventional MR imaging in patients with MS and controls. MATERIALS AND METHODS Twent...
BACKGROUND Tumor volume may serve as a predictor of response to radiochemotherapy (RCT) in head and neck squamous cell carcinoma (HNSCC). Computer assisted tumor volumetry requires time-consuming slice-by-slice manual or semi-automated segmentation. We questioned how accurately primary tumor and suspect cervical lymph node (LN) volumes can be approximated by the maximum tumor diameters in three...
The problem of chronic traumatic encephalopathy is extremely relevant from both medical and sports points view. Unfortunately, in the domestic literature to date, this issue not discussed enough. consequences repetitive mild brain injury play an important social role, which determines relevance studying need develop methods for solving it. This article provides a brief review on athletes predom...
