Whole-body CT screening : scan delay and contrast injection duration for optimal enhancement of abdominal organs and deep vessels . PURPOSE To assess the optimal scan delays and contrast injection durations for contrast-enhanced whole-body computed tomography ( CT ) . MATERIALS AND METHODS One hundred forty-two patients were randomized into three groups : protocol A-scan delay of 65 s after starting contrast injection over 30 s ; protocol B-105 and 70 s ; and protocol C-145 and 110 s , respectively . Contrast enhancement and diagnostic acceptability were assessed . RESULTS Qualitative assessment was subtle among the three protocols . Homogenous enhancement of deep veins was more assuredly achieved with protocol C. CONCLUSION With protocol C , qualitatively acceptable enhancement can be obtained in whole-body CT .
