目的：分析小肝癌(SHCC)的螺旋CT三期增强扫描的表现特征及血供特点,提高CT对小肝癌的定性诊断。方法收集16例经手术病理证实的小肝癌病例,术前行多层螺旋CT三期(动脉期、门脉期、延迟期)增强扫描,回顾性分析16例小肝癌患者的多层螺旋CT三期增强诊断结果。结果16例共发现18个病灶,其中动脉期病灶高密度强化16例、等密度1例、低密度1例。门脉期病灶高密度强化1例,等密度3例,14例为低密度,延时期病灶高密度1例,等密度2例,低密度为15例。其中1例CT检查未发现病灶。结论多层螺旋CT三期增强扫描是小肝癌可靠的检查方法,能充分反应小肝癌的血供特点,少数为不典型血供病灶。

Objective To evaluate the features of three-phase spiral CT scanning performance and blood supply properties of small hepatocellular carcinoma (SHCC), and then improve the CT diagnosis of SHCC. Methods 16 cases of SHCC confirmed by operation and pathology were collected. The fingings of enhanced multi-slice spiral CT with three phase (arterial portal and delayed) before operation were analysed retrospectively. Results 18 lesions were detected in 16 cases by CT scan. The lesions were manifested hyper-intensity(16), iso-intensity(1) and hypo-intensity(1) in arterial phase , hyper-intensity(1), iso-intensity(3) and hypo-intensity(14) in portal phase , hyper-intensity(1), iso-intensity(2) and hypo-intensity(15) in delayed phase . 1 lesion was not detected by CT. Conclusion Enhanced multi-slice CT with three phase is a reliable Methods for diagnosis HCC and it can reflect. the characteristics of the blood supply of SHCC.
