Optimal scan delay of arterial phase scanning of hepatic CT using a real-time image reconstruction system


      To optimize scan delay of arterial phase scanning of hepatic CT, 30 patients suspected of having HCC were examined using real-time image reconstruction technology (SureStart). In all cases, SureStart was successful. Despite the low dose, these images allowed adequate visualization of the abdominal aorta. The mean delay from the initiation of contrast administration to the beginning of arterial phase scanning was 29.6 ± 5.2 sec (mean ± SD; range, 22–51 sec).
