Fig. 1. —Diagram shows appearance of intranodular hemodynamic patterns on contrast-enhanced coded harmonic angio images. Tumor is shown as circle within liver. Tumor vessel is shown as linear or kinking lines in scheme on real-time scan. Enhancement of nontumoral tissue is shown in light shading, whereas highly contrast-enhanced tumor is shown in dense shading and unenhanced tumor is shown as blank space in scheme in interval-delay and sweep scan. Enhanced vessels, or area in interval-delay scan, are shown as denser shading than surrounding tumoral tissue.
