Walgraeve MS, et al. - Data of 77 individuals who underwent two contrast-enhanced CT-examinations were obtained in order to assess the influence of a patient-tailored contrast volume protocol on portal venous phase abdominal CT-images in comparison with a fixed volume protocol in daily radiological practice. Irrespective of a notable contrast volume decrease in women and in patients with low to normal BMI, the improvement was more consonant over various BMI-categories in the patient-tailored contrast volume protocol and no important distinction in subjective image quality between both injection protocols was noted. Therefore, in women and in low to normal BMI individuals, a patient-tailored contrast volume protocol based on body surface area and heart rate could be acknowledged in daily radiological practice in order to reduce contrast volumes and to attain more constant contrast enhancement across various BMI-categories in venous phase abdominal CT.
