目的: 探讨螺旋CT双期或多期扫描技术对肝内小于3 cm或CT表现不典型的肝小血瘤的诊断和鉴别诊断的意义。方法:采用双期或多期全肝和局部动态扫描。结果:直径小于3cm的肝小血管瘤增强表现复杂,呈多样化的影像。结论:肝小血管瘤的鉴别诊断的正确率与CT扫描技术密切相关,而观察延迟和扫描病灶密度的充盈程度尤为重要。
Objective: To investigate the significance of spiral CT double-phase or multi-phase scanning in the diagnosis and differential diagnosis of hepatic small cell tumor with less than 3 cm in diameter or CT. Methods: Double or multi-stage whole liver and local dynamic scanning. Results: Hepatic hemangiomas smaller than 3 cm in diameter showed complicated and varied images. Conclusion: The correct rate of differential diagnosis of Hepatic hemangioma is closely related to CT scan technique. However, it is very important to observe the delay and the degree of filling of the lesion density.
