目的探讨小肝癌患者诊断中应用多层螺旋CT三期增强薄层扫描的价值。方法回顾性分析57例小肝癌患者的多层螺旋CT三期增强扫描诊断结果,三期增强扫描分别为:动脉期扫描、门静脉期扫描、延迟期扫描。结果三期增强薄层扫描检出率以延迟期最高(96.49%);大多数的SHCC(68.4%)在三期增强扫描上表现典型,即“快进快出”;少数表现不典型。结论薄层扫描能提高SHCC检出率,综合三期扫描的表现可提高诊断和鉴别诊断能力。
Objective To evaluate the value of multi-slice spiral CT in the diagnosis of small hepatocellular carcinoma (HCC) in the third phase. Methods Retrospective analysis of 57 cases of small hepatocellular carcinoma patients with multi-slice spiral CT triple enhanced diagnostic results, three enhanced scan were: arterial phase scan, portal venous phase scan, delayed phase scan. Results The third phase enhanced TLC showed the highest delay (96.49%). Most of the SHCCs (68.4%) exhibited typical triple enhanced scanning, ie, “fast-forward and fast-out” . Conclusion Thin-section scanning can improve the detection rate of SHCC. The comprehensive three-stage scanning can improve the ability of diagnosis and differential diagnosis.
