    This study found no significant differences in brain ventricular size between chronic schizophrenic patients and control groups using standard imaging indices. These findings suggest ventricular-brain ratio may not be a reliable indicator for schizophrenia diagnosis.

    Area of Science:

    • Neuroimaging
    • Psychiatry
    • Radiology

    Background:

    • Schizophrenia is a complex mental disorder.
    • Brain structural abnormalities are often reported in schizophrenia patients.
    • The ventricular-brain ratio is a common neuroimaging metric.

    Purpose of the Study:

    • To investigate if specific brain imaging indices differ between chronic schizophrenic patients and healthy controls.
    • To assess the diagnostic utility of ventricular-brain ratio, Ewans' index, and cella media index in schizophrenia.

    Main Methods:

    • Computed tomography (CT) scans were analyzed.
    • Ventricular-brain ratio, Ewans' index, and cella media index were calculated.
    • A cohort of 46 chronic schizophrenic patients and 46 controls was studied.

    Main Results:

    • No statistically significant differences were observed in any of the measured indices between schizophrenic patients and controls.
    • The computed tomography (CT) scan analysis did not reveal group-specific patterns.

    Conclusions:

    • The studied neuroimaging indices, including ventricular-brain ratio, do not appear to differentiate chronic schizophrenic patients from healthy individuals.
    • Further research is needed to identify reliable neuroimaging biomarkers for schizophrenia.
