Assessment Of Radiation Dose For Patients Undergoing Brain And Abdomen Computed Tomography

Abstract

Computed tomography (CT) is an imaging technique which produces a digital

topographic image from diagnostic x-ray. It always considered a “high dose”

technique, there is growing realization that image quality in CT often exceeds

the level needed for confident diagnosis and that patient doses are higher than

necessary.

The aim of this study was to evaluate the level of radiation dose received by the

patients during brain and abdomen CT examination. In this study, a total of 128

adult patients undergoing brain and the abdominal CT scanning exams were

evaluatedusing CT Dose index and dose length product (DLP)

The result of this study revealed that the mean effective dose for abdomen in

hospital (1) and hospital (2) was(64.31 ± 29.8)mSv and (71.61 ± 0.97)

mSvrespectively. The mean effective dose for brain in hospital (1) and hospital

(2) was (2.96 ± 0.97)mSv, (3.11±0.51)mSv respectively. These values were

found to be at standard dose reference level.

Unjustified screening the Abdomen and head should thus be banished. Such

policy is unacceptable in young patients who are at a low risk of having an

incidental associated disease. Similarity, repeated acquisition should not be

performed in circumstances where they do not specifically yield additional information.
