16排螺旋CT多期增强扫描对早期肝癌的诊断

16 row of screw CT multi--time enhancement scanning to early liver cancer diagnosis

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：The analysis early time liver cancer various issue of enhancement image characteristic, enhances the early liver cancer to pick out rate. Methods：Occupies the position 74 examples after the surgery pathology or the clinical revisit confirma- tion diameter 3cm following liver,applies 16 row of screw CT multi--time enhancement scanning, carries on various issue of image reconstruction. Result：The primary hepatocellular carcinoma strengthens in the artery time performance for the high density, does not have the strengthening in the vein time performance for the low density,does not have the strengthening in the balance time per- formance for the low density. Conclusion： 16 row of screw CT multi--time enhancement scanning is diagnoses the early liver cancer effective method.
