About

Patients with liver cirrhosis is at risk of developing HCC. To diagnose or detect HCC at CT/MRI, optimal late arterial phase (LAP) acquisition is critical to capture the tumor. For LAP acquisition, bolus-tracking is often used at CT. In patients with portal hypertension, however, bolus-tracking occasionally capture early arterial phase which may be related with slow portomesenteric flow. In this study, we obtain dual arterial phase in patients with suspected portal hypertension and determine whether this protocol (dual arterial phase) would provide higher incidence of LAP acquisition than single arterial phase acquisition.
