摘　　要：目的探讨颅脑CT增强延迟薄层扫描时造影剂外溢形成的“点征”对脑出血早期血肿扩大的预测价值。方法 选择2013年1月~2015年12月我院自愿接受检测的6 h内急性自发性脑出血患者30例,进行基线CT平扫、增强CT延迟薄层扫描及24 h后复查CT平扫检查,依据“点征”结果分为“点征”阳性组和“点征”阴性组。结果 “点征”阳性组13例、“点征”阴性组17例,阳性预测值为76.9%,阴性预测值为94.2%。结论 颅脑CT增强延迟薄层扫描时造影剂外溢形成的“点征”可有效预测脑出血早期血肿扩大。Objective To explore the predictive value of ＂dot sign＂ formed by contrast agents extravasation during delayed contrast-enhanced CT scan on expansion of intracranial hematoma at an early stage.Methods Thirty patients with acute and spontaneous intracerebral hemorrhage within 6 hours accepted the detection in their own will in our hospital from January 2013 to December 2015 were selected and provided with baseline CT scan,delayed contrast-enhanced CT scan and CT scan for reexamination after 24 hours.According to outcomes of ＂dot sign＂,patients were divided into positive ＂dot sign＂ group and negative ＂dot sign＂ group.Results There were 13 and 17 cases in positive ＂dot sign＂ group and negative ＂dot sign＂ group respectively.The positive and negative predictive value was 76.9% and 94.2% respectively.Conclusion ＂Dot sign＂ formed by contrast agents extravasation during delayed contrast-enhanced CT scan can effectively predict the expansion of intracranial hematoma at an early stage.
