1、新疆医科大学硕士学位论文超声，CT对卵巢原发性恶性肿瘤的诊断价值研究生：吕娟导师：马富成主任医师摘要目的：探讨卵巢原发性恶性肿瘤的超声、CT表现，评估临床超声、CT及其联合对卵巢原发性恶性肿瘤的诊断价值及对分期的帮助。方法：回顾性分析我院经手术病理证实的88例卵巢原发性恶性肿瘤的临床及影像学资料，就其结果进行分析，其中88例卵巢原发性恶性肿瘤患者均行超声、CT检查，运用四格表分别计算超声、CT及超声联合CT各自的敏感性、特异性和准确性。并就其准确度绘制ROC曲线，比较超声、CT及超声联合CT的诊断准确度。并就卵巢原发性恶性肿瘤的几处转移分别做超声、CT诊断与病理诊断的一致性

2、分析。结果：卵巢恶性肿瘤诊断的灵敏度、特异度，超声、CT及超声与CT联合检查分别为76.14%/81.82%/92.05%、83.33%/89.58%/95.83。超声、CT及联合诊断的ROC曲线图说明超声、CT单独诊断时诊断准确性中等，而两者联合检查时诊断准确性较高。同时超声、CT对各处转移与病理的一致性分析说明两者对临床分期均可以提供依据。结论：超声、CT单独检查诊断的准确性不及二者联合诊断的准确性高，超声、CT诊断可以为卵巢原发性恶性肿瘤的临床分期提供依据。关键词：卵巢原发性恶性肿瘤；超声；CT1新疆医科大学硕士学位论文InvestigationofUltrasono
