Functional magnetic resonance imaging of brain of college students with internet addiction / 中南大学学报(医学版)

OBJECTIVE@#To explore the functional locations of brain regions related to internet addiction (IA)with task-functional magnetic resonance imaging (fMRI).@*METHODS@#Nineteen college students who had internet game addition and 19 controls accepted the stimuli of videos via computer. The 3.0 Tesla MRI was used to record the Results of echo plannar imaging. The block design method was used. Intragroup and intergroup analysis Results in the 2 groups were obtained. The differences between the 2 groups were analyzed.@*RESULTS@#The internet game videos markedly activated the brain regions of the college students who had or had no internet game addiction. Compared with the control group, the IA group showed increased activation in the right superior parietal lobule, right insular lobe, right precuneus, right cingulated gyrus, and right superior temporal gyrus.@*CONCLUSION@#Internet game tasks can activate the vision, space, attention and execution center which are composed of temporal occipital gyrus and frontal parietal gyrus. Abnormal brain function and lateral activation of the right brain may exist in IA.

Measurement of intracranial hematoma volume by personal computer / 中南大学学报(医学版)

OBJECTIVE@#To explore the method for intracranial hematoma volume measurement by the personal computer.@*METHODS@#Forty cases of various intracranial hematomas were measured by the computer tomography with quantitative software and personal computer with Photoshop CS3 software, respectively. the data from the 2 methods were analyzed and compared.@*RESULTS@#There was no difference between the data from the computer tomography and the personal computer (P>0.05).@*CONCLUSION@#The personal computer with Photoshop CS3 software can measure the volume of various intracranial hematomas precisely, rapidly and simply. It should be recommended in the clinical medicolegal identification.
