Garcia-Garrigos E, et al. - Experts aimed to estimate the superiority of either of 2 protocols [Protocol A consisted of two acquisitions: One 35-second delayed CT acquisition for the chest followed by a 70-second delayed abdominal acquisition; Protocol B was a single 60-second delayed acquisition covering the chest and the abdomen] for combined contrast-enhanced thoracic and abdominal CT of patients with lung cancer by comparing contrast enhancement, contrast-related artifacts, image quality, and radiation dose. A connection was illustrated between a single 60-second delayed acquisition for thoracic and abdominal contrast-enhanced CT with less contrast artifact, through which better visualization of lymph nodes was obtained at a lower radiation dose while maintaining acceptable vascular and hepatic contrast enhancement.
