Evaluation of normal measurements of fourth ventricle by computed tomography

Background: Size of fourth ventricle varies in different pathologies, the context enlarged brain ventricles size observed routine clinical practices, knowledge usual range exact measurement is required. Aims and Objectives: This study hospital-based observational to derive normal correlating it with measurements cerebrum age patients. Materials Methods: Hospital-based prospective was conducted department radiodiagnosis a teaching medical college. Patients virtually on unenhanced head CT scan both sex groups from 2 year 60 years, were included study. scans showing gross pathological changes affecting anatomy excluded Results: The mean cases 37.0±16.88 years. Mean anterioposterior dimension 7.5±2.5 mm transverse 12±3.1 mm. Anteroposterior diameter showed non-significant correlation (r=0.06, P=0.56) anteroposterior skull no significant (r=0.07, P=0.45) (TD) skull. AP positive age, which statistically (r2=0.698, P=0.01). TD slight (r=0.202 P=0.048) (r=0.142, P=0.168) whereas nil with. (r2=0.659, It increases age. Conclusion: Knowledge helps assessing, dilated various pathologies.
