In high risk population, HCC is best detected by:
Ans. (a) USGRadiological Investigations for HCC:Imaging Investigation of Choice- Triple Phase CECT abdomenClassical features are:* Arterial Hyper vascularization* Early Wash out in Venous PhaseSmall HCC in Three phases is shown here. See the enhancement in arterial phase and wash out in Venous PhaseHCC Confirmation: (As per NCCN guidelines 2015)* For lesions 1-2cm: 2 Imaging techniques (CECT and MRI)* Focal Lesions >2cm: One imaging technique with Arterial Hyper vascularization and venous wash out is enough.* Screening is based on USG Scanning of High risk population (Like HBV induced Cirrhosis)* Biopsy is not required to prove its an HCC.
