Abstract:
Objective To study the CT features of small hepatocellular cancer.Methods 37 patients with small hepatocellular cancer proved histopathologically underwent spiral CT examinations including plain scans and contrast-enhanced scans.The arterial phase scan,the portal phase scan and delayed phase scan started at 25th second,70th second and 5th minute respectively after injecting the contrast medium with the high pressure syringe,the velocity was 2.5 ~3 ml/s,and the dose was 1.5 ml/kg.Results 73% (27/37) of tumors showed hyperdensity in arterial phase,65%(24/37) of tumors was hypodensity and 35% (13/37) had hyperdensity during portal phase,of which eight showed hypodensity in equilibrium phase.Conclusion Spiral CT can display the features of blood supply of small hepatocellular carcinoma that is of benefit in early diagnosis.
