[Abstract] Objective: To discuss the imaging characteristics of the hepatic veno-occlusive disease (HVOD).Materials and Methods: Four cases of HVOD were retrospectively analyzed. Each of the case was scanned by MRI in 3 dynamic phases after contrast enhancement and ultrasound. Three of the 4 cases were also dynamically scanned CT. The analysis was focused on the dynamic change of the parenchyma and the vasculature system and compared with that of pre-contrast images.Results: Two cases were diagnosed by biopsy with the other 2 confirmed by clinical signs. On pre-contrast MR images, enlarged liver, seroperitoneum, and heterogenous signal intensities of the parenchyma were revealed. On post-contrast images, the liver demonstrated nonhomogenous enhancement in arterial phase, patchy enhancement and low-perfusion in portal vein phase, and slow wash-out in delayed phase. The dynamic change on CT images was similar with that of MRI. All of the cases revealed non-obstructive hepatic veins and inferior vena cava in ultrasound examination.Conclusions: The findings of HVOD were non-specific in ultrasound, pre-contrast MR images, and pre-contrast CT. The signs of dynamic contrast images were more valuable for the diagnosis.
