目的分析和评价肝血管瘤螺旋CT平扫及动态增强扫描的CT表现及其诊断价值。方法选择本院在2013年10月至2016年7月间收治的67例肝血管瘤患者为研究主体。对其进行螺旋CT平扫,再行螺旋CT动态增强扫描。分析其临床资料,总结其CT表现和诊断价值。结果大部分肝血管瘤的CT平扫表现是肝内有多发或是单发椭圆形或圆形的低密度影,且边界较为清晰。经动态增强扫面后:动脉期结节,斑片状以及环状强化75个,门脉期的对比剂渐渐向病灶中心位置充填,没有明显强化病灶开始强化10个。之后的延迟扫描中可见造影剂继续向病灶中央位置填充,完全填充成等密度病灶78个,剩余7个病灶为部分填充。结论在肝血管瘤疾病的CT诊断中,采用螺旋CT动态增强扫描可在各个时期呈现出较明显的诊断特点,有其典型的CT表现。所以,CT扫描特别是螺旋动态增强扫描可以增强肝血管瘤诊断的正确性,具有较佳的诊断价值。
Objective To analyze and evaluate the CT findings and their diagnostic value of hemangiomas with spiral CT scan and dynamic contrast-enhanced scan. Methods Sixty-seven patients with hepatic hemangiomas admitted to our hospital from October 2013 to July 2016 were selected as the study subjects. Spiral CT scan, and then spiral CT dynamic enhanced scan. Analyze its clinical data, summarize its CT performance and diagnostic value. Results Most of the hepatic hemangiomas showed CT manifestations of multiple or single intracranial oval or circular low density, and the border is more clear. After the dynamic enhancement of swept surface: arterial nodules, patchy and annular enhancement of 75, portal venous phase contrast agent gradually filled to the center of the lesion, no significant enhancement of the lesion began to strengthen 10. After the delayed scan shows that the contrast agent to continue to fill the central location of the lesion, completely filled into equal density lesions 78, the remaining seven lesions partially filled. Conclusions In the CT diagnosis of hepatic hemangioma diseases, the dynamic contrast-enhanced spiral computed tomography (CT) can present more obvious features of diagnosis in all stages with typical CT findings. Therefore, CT scan especially helical dynamic contrast-enhanced scan can enhance the diagnosis of hepatic hemangiomas and has better diagnostic value.
