Core Tip	Since radiation can cause various effects in humans whether it is somatic or genetic, this study aims to determine whether there are any differences in the displayed and calculated radiation dose in case of head computed tomography (CT). To rule out the probability of under or over estimation of radiation dose for the same, as it is essential for radiation to be within the acceptable limits to prevent risk of cancer and other stochastic and deterministic effects. In our study we found that the size specific dose estimate is severely underestimated in the patient dose chart. This indicates the patient is exposed to much greater radiation than estimated so, there is a need for maintaining lowest possible dose criteria for scanning to prevent any probability of radiation induced effects in the patient. Study of this type has not been done in this area and provides impactful insights on the dose underestimation in head CT.
