Value of dynamic multidetector CT in different grades of hepatocellular carcinoma

PurposeTo evaluate dynamic multidetector CT (MDCT) in assessment of grades of hepatocellular carcinoma (HCC).Patients and methodsForty patients of HCC were assessed. Enhancement patterns were correlated with pathological grades.ResultsThree enhancement patterns were:1.Hyperattenuating lesions in portal venous phase.2.Hypoattenuating lesions in all phases.3.Hyperattenuating lesions in arterial phase.ConclusionArterial and portal biphasic imaging was the most informative in assessment of tumor grades. High grade lesions were hyperattenuating in arterial phase.At initial evaluation, triphasic imaging is advisable, while in diagnosed cases and on follow up, biphasic imaging could be satisfactory.
