| 摘 要： | 目的:分析CT平扫及增强扫描在鉴别肝脏血管肉瘤(PHA)和肝脏血管瘤(CHH)中的应用价值。方法:收集8例有明确病理结果的PHA患者及30例经病理证实为CHH患者的CT影像学资料,所有患者入院后均完成CT平扫及增强扫描(MSCT),分析肝血管肉瘤、血管瘤影像学特点及CT鉴别价值。结果:PHA结节CT平扫密度不均匀所占比例高于CHH结节(P<0.05);PHA结节强化位置非周边率高于CHH (P<0.05);PHA结节伴瘤周静脉短路比例高于CHH,其边界不清晰所占比例高于CHH结节(P<0.05),但两者强化形态、延迟期强化特点及CT值对比差异无统计学意义(P>0.05)。结论:PHA以中心斑片状逐渐强化为特点,呈非周边强化,动静脉短路率高;CHH则以周边强化常见,动静脉短路率低。

| Abstract: | Objective: To analyze the application value of CT scan and enhanced scan in the differential diagnosis of hepatic angiosarcoma (PHA) and hemangioma (CHH). Methods: The CT imaging data of 8 patients with pathologically confirmed PHA and 30 patients with pathologically confirmed CHH were collected. All patients underwent CT plain scan and enhanced scan after admission. The imaging characteristics of hepatic angiosarcoma and hemangioma and the diagnostic value of CT were analyzed. Results: The proportion of uneven density in PHA nodules scanned by CT was higher than that in CHH nodules (P < 0.05); The non-peripheral rate of enhanced PHA nodules was higher than that of CHH (P < 0.05); The ratio of PHA nodules with peritumoral venous shunt was higher than that of CHH, and the ratio of unclear boundaries was higher than that in CHH nodules (P < 0.05), while the enhancement pattern, delayed enhancement characteristics and CT value showed no significant differences (P > 0.05). Conclusion: PHA is characterized by gradual central patchy enhancement, non-peripheral enhancement, and high ratio of arteriovenous shunt while CT of CHH is characterized by peripheral enhancement and low ratio of arteriovenous shunt. |
