摘要
目的分析增强CT、超声联合检测在术前鉴别卵巢病变良恶性中的价值及影像特点。方法回顾性分析我院2014年3月-2017年8月间收治的300例卵巢病变患者影像学资料,以病理检查结果为标准,评估增强CT联合超声检测在鉴别卵巢病变良恶性中的价值。结果病理检查结果提示,300例卵巢肿瘤患者中有81例为恶性肿瘤,219例为良性肿瘤,81例恶性肿瘤患者中单侧病灶53例,双侧病灶28例;伴淋巴结转移者23例,侵犯周围组织脏器者41例;CT诊断灵敏度为87.21%、特异度为81.48%、准确度为85.67%,CT检查能有效定位病灶位置、检测病灶密度,提示病灶内部结构与形态特征,且病灶转移等征象明显,恶性病变在增强扫描时囊壁及间隔明显强化,实性成分不均匀强化;超声诊断灵敏度为93.15%、特异度为92.59%、准确度为93.00%,超声检查方式多样,能有效显示病灶形态、结构、内部血流信号等特征;增强CT联合超声检查灵敏度为96.35%、特异度为97.53%、准确度为96.67%。结论增强CT联合超声检查可弥补单纯检查的不足,有效提高卵巢肿瘤良恶性诊断效果,值得临床推广。
Objective To analyze the value and imaging features of enhanced CT combined with ultrasound in the preoperative identification of benign and malignant ovarian lesions. Methods The imaging data of 300 patients with ovarian lesions admitted to our hospital from March 2014 to August 2017 were analyzed retrospectively. The results of pathological examination were taken as criterion to evaluate the value of enhanced CT combined with ultrasound in the identification of benign and malignant ovarian lesions.Results Pathological examination results showed that there were 81 cases of malignant tumors and 219 cases of benign tumors among 300 patients with ovarian tumors, and there were 53 cases of unilateral lesions and 28 cases of bilateral lesions among 81 patients with malignant tumors. There were 23 cases patients with lymph node metastasis and41 cases with invasion of surrounding organs. The diagnostic sensitivity, specificity and accuracy of CT were 87.21%, 81.48% and 85.67%, and CT examination could effectively diagnose the lesion location, detect the lesion density, suggest the internal structure and morphological characteristics of lesion, and metastasis, and had obvious signs of lesion metastasis. And malignant lesions were with obvious enhancement in capsule wall and interval, and unevenly enhanced solid components during enhanced scan. The sensitivity,specificity and accuracy of ultrasound were 93.15%, 92.59% and 93.00%, respectively. The ultrasonic examination methods were various and could effectively show the features of lesion morphology, structure and internal blood flow signal. The sensitivity, specificity and accuracy of enhanced CT combined with ultrasound were 96.35%, 97.53% and 96.67%,respectively. Conclusion Enhanced CT combined with ultrasound can increase the deficiency of simple examination, and effectively improve the diagnostic effects of benign and malignant ovarian tumors, thus it is worthy of clinical promotion.
