Abstract:
Objective The BOLD -fMRI(blood oxygenation level dependent functional magnetic resonance imaging)was used to observe the functional cortical activities of the bilateral cerebral hemispheres in 23 cases of chil_dren with congenital sensorineural hearing loss under resting state ,and to further explore the values of BOLD-fM_RI in patients with sensorineural hearing loss .Methods Twenty three children with congenital sensorineural hearing loss were included in the experimental group and 10 normal heating children were included as cronol group .The ALFF(amplitude of low -frequency fluctuation) method was used to analyze the image data ,and to compare the ex_perimental and control groups with bilateral cerebral cortex function activities for the quantitative analysis .ResuIts The resting state activity intensity in the left inferior temporal gyrus ,left fusiform gyrus ,right cingulate gyrus and left post central gyrus of the experimental group were significantly greater than those of in the corresponding intensi_ty cortex of the control group (P< 0 .01) .ConcIusion The cortex of sensory systems in children with congenital sensorineural deafness may have functional remodeling ,cerebral cortex of patients with sensorineural hearing loss may have perception compensation phenomenon .
