Intervention(s) planned
Study setting Department of Radiology- CNTH-Ragama.
All eligible patients will be randomized to the intervention or control group using computer generated random numbers.
Intervention group patients will be exposed to tube current value of 130 milliamperes (Ma).
Control group will be exposed to manufacturer set default tube current value of 300 milliamperes (Ma) which is practiced currently.
A radiographer will carry out the CT examinations in control and study groups. Helical CT will be performed parallel to cantho-meatal line from skull base to vertex. Hard copy CT films will be printed for each patient to use image quality analysis.
Outcome assessors will be blinded to the intervention.
Inclusion criteria
• Patients of 18 years and above • Men and women • Patients who are sent the Radiology department for routine non contrast CT brain (Both traumatic and non traumatic).
Exclusion criteria
• Pregnant Patients
• Critically ill patients
• Unconscious patients
• Patients who are not able to provide information.

Do the investigators plan to share identified individual clinical trial participant-level data (IPD)?
Yes
IPD sharing plan description
Individual participant data that underlie the results will be shared after the de-identification (tables,figures,appendices). The study protocol will also be available. This will be immediately following publication (no end date). Data sharing will be with investigators whose proposed use of the data has been approved by an independent review committee/ethical review committee identified for this purpose. Data will be made available for IPD meta analysis.
