From: Noise insertion in CT for cocaine body packing: where is the limit of extensive dose reduction?
A 58-year-old individual suspected of body packing. CT examination was performed at 80 kVp with ATCM (tube current time product: 81 mAs, dose level 100% effective dose at 100%: 1.09 mSv). Axial CT scans (soft tissue window, window level 40/300) with stepwise dose reduction (100%, 50%, 10%, 5%, and 1%). In this case at 1% of initial dose (0.02 mSv), one additional false-positive solid body packet was rated by reader one (white arrow)
