目的分析早期肝癌的各期增强图像的特点,提高早期肝癌的检出率。方法经手术病理或临床随访证实的直径3cm以下的肝占位74例,应用16排螺旋CT多期增强扫描,进行各期图像重建。结果原发性肝细胞癌在动脉期表现为高密度强化,在静脉期表现为低密度无强化,在平衡期表现为低密度无强化。结论16排螺旋CT多期增强扫描是诊断早期肝癌行之有效的方法。
Objective To analyze the characteristics of early stage liver cancer enhancement images and improve the detection rate of early stage liver cancer. Methods Totally 74 patients with liver diameter less than 3 cm confirmed by operation and pathology or clinical follow-up were enrolled in this study. Results Primary hepatocellular carcinoma showed high density enhancement in arterial phase, low density non-enhancement in venous phase and low density non-enhancement in balance phase. Conclusion 16-slice spiral CT multi-phase enhanced scan is an effective method for the diagnosis of early stage liver cancer.
