Abstract

Globally, variation in dose to patients' undergoing same radiological examination from same or other facility have been severally reported. The equipment, as well as the technique of exposure, has been scrutinized in order to find the reason for this noticeable discrepancy and reduce it. This work has considered patient's size and shape as one of the identifiable variation factor in patient dose evaluations, which has been shown to relate exponentially to the energy imparted during pelvis examination. Therefore, different approaches to measuring AP trunk thickness in patients' undergoing pelvis examination were adequately compared for accuracy purposes. Study therefore established that there is significant relation in all the methods identified for measuring patient's AP trunk diameter, except for several areas of error as may be identified as constituting to higher degree of discrepancies in the measured values. Finding showed that average AP trunk thickness ranged between 20.4cm and 24.6cm for pelvis examination in the centres studied for standard adult patients, gender wise. It is therefore suggested that these values be used as a baseline for further study in establishing AP trunk diameter for a standard adult patient in Nigeria. Consequently, predicted (20 to 30) % reduction in dose variation from radiological examinations with accurate thickness (diameter) measurement.
