Abstract: Objective To study the diagnostic value of contrast-enhanced CT patterns in focal hepatic lesions.Methods Contrast-enhanced CT patterns in 44 patients with focal hepatic lesions (54 foci) were retrospectively analysed.Results (1)78% of the hepatocellular carcinoma presented "rapid-filling and rapid-washout" feature.(2)All hepatic hemangioma presented "rapid-filling and slow-washout", progressive opacification from the periphery to center. (3)All cholangiocarcinoma presented "slow-filling and slow-washout" .(4)Metastatic hepatocarcinoma in 14 cases and hepatic abscesses in 5 cases were presented a enhanced ring around the lesion, metastatic hepatocarcinomas showed single ring,however, hepatic abscesses showed multi-ring. (5)Focal nodular hyperplasia in 3 cases and hepatic adenomas in 1 case presented "rapid-filling and slow-washout".Conclusion The contrast-enhanced patterns at spiral CT can fully reflect the blood supply of focal hepatic lesions, it has significant value in diagnosing focal hepatic lesions.
