| 摘 要： | 目的 探讨小肝癌的CT表现特征.方法 37例经手术病理证实的小肝癌分别行螺旋CT平扫及三期扫描,扫描时间分别为动脉期25 s,门脉期70 s,延迟期5 min,用高压注射器经肘静脉注射,速率为2.5~3 ml/s,剂量为1.5 ml/kg,分析其CT表现特征.结果动脉期73%(27/37)肿瘤病灶呈高密度,门静脉期65%(24/37)呈低密度,35%(13/37)呈高密度,其中8例平衡期呈低密度.结论螺旋CT三期扫描能反映出小肝癌的血供特点, 有利于早期诊断.

| 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. |
