Liver nodules were examined by US, CT, MRI, and CT during arterial portography (CTAP), CT arteriography (CTA), and 99mTc-stannous colloid scintigraphy, and the imaging features of the nodules were as follows. The nodules increased radionuclide uptake on 99mTc-stannous colloid scintigraphy. On ultrasonography, three nodules at S3, S5, and S6 showed hyperechogenicity, although many were not identified. Power Doppler mode showed rich vascularity within the hyperechoic nodules, and FFT analysis showed continuous wave. CTAP and CTA showed that the blood supply to the nodules was mainly portal. Pathologic evaluation showed definite nodular transformation, and a dilated portal vein was found within the large nodules. These findings clearly appear to reflect the pathologic features of the nodules.
