目的 探讨CT扫描对卵巢肿块的诊断价值及限度。方法 应用Max6 40型全身CT机 ,对 75例共 82只卵巢肿块进行普通及增强扫描检查 ,并对照手术病理结果分析。结果 1.肿瘤性肿块特点 :a)实性或囊实性。b)囊性肿块内有分隔、囊壁厚薄不均或有结节。c)囊性肿瘤内有脂肪、钙化或骨骼 ,是囊性畸胎瘤的特征。 2 .非肿瘤性肿块 :囊壁菲薄 ,均匀液体密度无结节。 3.肿瘤良、恶性的鉴别要点在于观察肿块囊壁形态、厚度、结节大小及周围浸润转移等。结论 CT对卵巢肿块的定位及定性诊断准确率分别为 92 .7%及 93 7%。
Objective To investigate the diagnostic value and limit of CT scan on ovarian tumor. Methods Using Max6 40 type CT machine, 75 cases of 82 ovarian masses were examined by routine and contrast-enhanced CT scans. The pathological results were analyzed. Results 1. Tumor features: a) solid or cystic solid. b) cystic mass within the separation, uneven wall thickness or nodules. c) cystic tumors with fat, calcification or bone, is characterized by cystic teratoma. 2 non-tumor mass: thin wall, uniform liquid density without nodules. 3. Tumor benign and malignant differentiate the main point is to observe the tumor wall morphology, thickness, nodular size and surrounding infiltration and metastasis. Conclusion The accuracy of localization and qualitative diagnosis of ovarian masses by CT is 92.7% and 93.7% respectively.
