[Aberrant topological properties of whole-brain functional network in chronic right-sided sensorineural hearing loss: a resting-state functional MRI study].

Objective: To investigate the topological properties of the functional brain network in unilateral sensorineural hearing loss patients.

Methods: In this study, we acquired resting-state BOLD- fMRI data from 19 right-sided SNHL patients and 31 healthy controls with normal hearing and constructed their whole brain functional networks. Two-sample two-tailed t-tests were performed to investigate group differences in topological parameters between the USNHL patients and the controls.

[Arterial remodeling in middle cerebral artery atherosclerotic stenosis:a high-resolution MRI study].

Objective: To investigate remodeling mode of moderate or severe atherosclerotic stenosis of the middle cerebral artery (MCA) using high resolution MRI.

Methods: Thirty-seven consecutive symptomatic patients with atherosclerotic MCA stenosis were imaged with a 3.0-T magnetic resonance scanner.
