Effects of Patient Size and Radiation Dose on Iodine Quantification in Dual-Source Dual-Energy CT

ConclusionReliable iodine quantification can be achieved using dual-source CT, but the result can be affected by patient size and dose rate. In large patients, biases may occur due to the beam-hardening and the photon-starvation effects, in which case higher dose rate and higher kVp are recommended to minimize these effects.
