摘要

BACKGROUND Multi-phase computed tomography(CT)or magnetic resonance imaging(MRI)has been the standard of care for hepatocellular carcinoma(HCC)diagnosis for years.CASE SUMMARY We report a case series of four patients in whom positron emission tomographycomputed tomography(PET-CT)scan complemented the conventional CT/MRI scans in evaluating treatment response.In these four cases the conventional multi-phase CT and MRI failed to identify residual HCC disease post-treatment,while PET-CT complemented and aided in treatment response evaluation.In each case,the addition of PET-CT identified and located residual HCC disease,allowed retreatment,and altered medical management.CONCLUSION This case series suggests that PET-CT should perhaps play a role in the HCC management algorithm,in addition to the conventional contrast-enhanced multiphase scans.
