Characterisation of hepatobiliary lesions in an African referral hospital: initial MDCT dose challenges

Methods A crossectional survey was carried out on 69 patients who underwent triple phase CT imaging for suspected hepatobiliary neoplastic involvement at a referral hospital in Kenya that had acquired its first multidetector CT scan (16 slice) between July 2008 and March 2009. Justification of examination (matching clinical indications and imaging findings), optimisation of scanning parameters such as mAs and KVp as well as radiation doses in dose length product (DLP) and effective dose were assessed.
