Characterization of thalamo-cortical association using amplitude and connectivity of functional MRI in mild traumatic brain injury.
To examine thalamic and cortical injuries using fractional amplitude of low-frequency fluctuations (fALFFs) and functional connectivity MRI (fcMRI) based on resting state (RS) and task-related fMRI in patients with mild traumatic brain injury (MTBI). ⋯ The decreased fALFFs (i.e., lower neuronal activity) in the thalamus and its segments provide additional evidence of thalamic injury in patients with MTBI. Our findings of fALFFs and fcMRI changes during motor task and resting state may offer insights into the underlying cause and primary location of disrupted thalamo-cortical networks after MTBI.

Study on cervical muscle volume by means of three-dimensional reconstruction.
To quantify the cervical muscle volume variation by means of three-dimensional reconstruction from MRI images. ⋯ This study provides initial results which could be used as reference data for clinical evaluation and biomechanical model development.

Combined value of susceptibility-weighted and perfusion-weighted imaging in assessing who grade for brain astrocytomas.
To assess the value of combining susceptibility-weighted imaging (SWI) and dynamic susceptibility weighted contrast-enhanced (DSC) perfusion-weighted MRI (PWI) in assessing World Health Organization (WHO)grade for brain astrocytoma . ⋯ ITSS was useful for assessing the WHO tumor grade in this cohort of patients with astrocytoma.The combination of SWI and PWI may improve the diagnostic accuracy of astrocytoma grading.

Functional magnetic resonance cholangiography enhanced with Gd-EOB-DTPA: effect of liver function on biliary system visualization.
To evaluate effect of liver function on biliary system visualization using gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance cholangiography (CE-MRC). ⋯ Different liver function according to Child-Pugh classification significantly affects biliary system visualization of Gd-EOB-DTPA CE-MRC.
