摘　　要：目的探讨CT检查在诊断等密度硬膜下血肿中降低漏诊率的方法。方法回顾性分析近年来本院收治的28例等密度硬膜下血肿患者的CT影像资料,总结其直接征象与间接征象的影像学特点。结果 28例患者血肿边界欠清晰,大小不等,新月形血肿25例,梭形血肿3例。结论 CT室医生在阅片诊断过程中应仔细,结合CT影像中提示的直接征象与间接征象综合分析,可提高等密度硬膜下血肿的诊断正确率,降低漏诊的发生率。Objective To investigate the methods of decreasing the omission diagnostic rate of CT for patients with isodense subdural hematoma. Methods CT images data of 28 cases of patients with isodense subdural hematoma in our hospital recent years were retrospectively analyzed, and the imaging features of their direct signs and indirect signs were summarized. Results Hematoma＇s boundaries of the 28 cases of patients were not clear, size were different. 25 cases showed crescent form, and 3 cases showed spindle shape. Conclusion In the course of the radiograph reading, we should do it very carefully, and comprehensive analyze the direct signs and indirect signs, so that we can increase the correct diagnostic rate and decrease the omission diagnostic rate.
