目的 :探讨肝转移瘤的CT表现特点 ,提高肝转移瘤的CT诊断水平。材料与方法 :对 10 7例经手术及临床病理证实的肝转移瘤的CT表现进行分析。结果 :10 7例肝转移瘤CT表现多发者 99例 ,占 92 5 % ;单发者 8例 ,占 7 5 %。表现“牛眼征”的 41例 ;等密度转移 9例 ;钙化性转移 4例 ;囊性转移 1例。增强扫描强化方式多样 ,环状强化较具有特征性 ,门脉期扫描病变显示最清晰。结论 :肝转移瘤CT表现多样 ,多发性是肝转移瘤的特征。
Objective: To investigate the CT features of liver metastases and to improve the CT diagnosis of liver metastases. Materials and Methods: CT findings of 107 liver metastases confirmed by surgery and clinicopathology were analyzed. Results: Of the 107 cases of liver metastases, 99 cases had multiple CT findings, accounting for 92.5%; 8 cases were single, accounting for 75%. The performance of “bull’s eye sign” in 41 cases; equal density transfer in 9 cases; calcified metastasis in 4 cases; cystic metastasis in 1 case. Enhancement of various enhanced scanning intensification, ring enhancement is more characteristic, the portal phase scanning lesions show the clearest. Conclusions: CT manifestations of liver metastases are diverse and multiple is a characteristic of liver metastases.
