Answer

Triple-phase CT (including an arterial phase, a portal venous phase, and a late washout phase) has been found to be highly accurate in the diagnosis and characterization of HCCs but, like US, may miss smaller lesions. Pooled estimates reveal a sensitivity of 68% and a specificity of 93%. [36] Disadvantages of CT include cost, radiation exposure, and the need for iodinated contrast.
