Contrast-enhanced CT shows hyperenhancement in the late arterial phase (a, white arrow), washout in portal venous phase (b, white arrowhead), and in delayed phase (c); a capsule is visible in delayed phase (c). The tumor was segmented on the portal venous phase by manually drawing a region of interest within the lesions margin (d), using a free software (LIFEx, www.lifexsoft.org), the corresponding histogram shows distribution of signal intensities within the region of interest (e)Back to article page
