Evaluation of a personalized total iodine dose (TID) combined with fixed injection duration (FID) protocol using high-concentration (400 mgI/mL) iodinated contrast medium in CT portal venography: a randomized trial
Background The portal vasculature is closely associated with clinical outcomes in liver disease. Contrast-enhanced computed tomography (CT) serves as the first-line noninvasive tool for its evaluation. The contrast administration strategy critically influences CT image quality and diagnostic performance. This study aim...
