Aim:Comparison of radiation dose in brain imaging between 16 and 64 slice CT. Materials and Methods:Sampling was done by convenience sampling method considering inclusion and exclusion criteria and a sample of 80 was included. 40 were scanned in 64 slice CT and 40 were scanned in 16 slice CT. Effective dose was computedfrom DLP using the equation; Eek: x DLPk=0.0021 (According to European guidelines). Statisticalanalysis was done using Mann-Whitney U test.Result:The 16 slice CT machine is delivering more radiation dose compared to 64 slice CTfor brain imaging with statistically significant difference. Conclusion.In the context of brain CT imaging using the same softwarefrom the same manufacturer, 64CT examinations provide gives a lower ED when compared with 16CT examinations.
