Abstract
|
|
|
The present study was undertaken to know whether there is change of T2 relaxation times in schizophrenics. The authors measured T2 relaxation times of 10 regions of interest in 27 schizophrenic patients and 24 control subjects. Using 2.0 tesla
brain MRI
scanner. The areas included were parahippocampal gyrus. globus pallidus, thalamus, cingulate gyrus, and prefrontal gyrus of both hemispheres. And we compared these T2 values between schizophrenics and control cases, and looked for differences
between
schizophrenic subgroups in terms of duration of the disorder.
There were no significant differences of T2 between 27 schizophrenics and 24 control subjects in 10 areas. Also regardless of sex, we could not find no differences of T2 between schizophrenics and controls subjects. The duration of illness was
not
associated with the T2 values of the patients. When the patients were divided into paranoid and non-paranoid groups, there was no difference except that T2 value of left cingulate gyri showed significant difference between two groups.
