Hepatic parenchymal hemodynamics of cholangitis with portal trunk thrombus using contrast-enhanced ultrasonography with Sonazoid: delineation of so-called central and peripheral zonal differentiation by arrival-time parametric imaging.

Abstract
We carried out contrast-enhanced ultrasonography using Sonazoid for a patient who had portal thrombosis due to choledocholith and cholangitis, and the video images were analyzed by an offline procedure using arrival-time parametric imaging. Colors were changed with the time course from red to orange, yellow, green, light blue, and blue, with the time the contrast agent reached the right hepatic artery as the starting point. The central part of the liver was primarily colored blue, and the peripheral part primarily yellowish-green. In other words, we confirmed the central and peripheral zonal differentiation observed in the arterial phase of dynamic computed tomography by color mapping image of arrival-time parametric imaging. Particularly, real-time changes in the hemodynamics of the hepatic parenchyma could be captured by color mapping image using arrival-time parametric imaging.
