目的 探究多层螺旋CT鉴别诊断卵巢囊腺肿瘤良恶性的效果。方法 选择2023年5月至2024年5月上海市老年医学中心就诊的卵巢囊腺肿瘤患者共60例参与本次研究,在对患者进行CT诊断和MR诊断后,行病理检查,对各检查结果进行分析。结果 病理检查发现,60例卵巢囊腺肿瘤患者中,20例黏液性腺癌,25例浆液性囊腺癌,11例子宫内膜样瘤,颗粒细胞瘤、透明细胞瘤、转移性肿瘤、纤维瘤患者各1例。MRI诊断准确度为81.67%（49/60）,高于CT的55.00%（33/60）（P<0.05）;60例卵巢囊腺肿瘤,6例Ⅰ期、9例Ⅱ期、20例Ⅲ期、25例Ⅳ期。MRI分期诊断符合率为（40/60）66.67%,高于CT诊断的91.67%（55/60）（P<0.05）;恶性组肿瘤直径和CT值均较良性组高（P<0.05）;恶性组实性、增强密度不均匀及腹水存在率均较良性组高（P<0.05）。结论 在卵巢囊腺肿瘤良恶性患者鉴别诊断中多层螺旋CT技术价值较好,可显著提升卵巢囊腺肿瘤患者诊断效能。

Objective To explore the effect of multilayer spiral CT on benign and malignant ovarian cystic gland tumors. Methods A total of 60 patients with ovarian sac gland tumors treated in Shanghai geriatrics from May 2023 to May 2024 were selected to participate in this study. After CT diagnosis and MR diagnosis of the patients, pathological examination was performed and the examination results were analyzed. Results Pathological examination found that among the 60 patients with ovarian cystic gland tumor, 20 patients had mucinous adenocarcinoma, 25 patients had serous cystic adenocarcinoma, 11 patients with endometrioma, and 1 patient each had granulosa cell tumor, clear cell tumor, metastatic tumor, and fibroma. Pathological examination found that among the 60 patients with ovarian cystic gland tumor, 20 patients had mucinous adenocarcinoma, 25 patients had serous cystic adenocarcinoma, 11 patients with endometrioma, and 1 patient each had granulosa cell tumor, clear cell tumor, metastatic tumor, and fibroma. The diagnostic accuracy of MRI was 81.67% (49/60), higher than that of CT 55.00% (33/60) (P<0.05). 60 cases of ovarian cystadenocarcinoma, 6 cases of stage I, 9 cases of stage II, 20 cases of stage III, 25 cases of stage IV. The coincidence rate of MRI staging was 66.67% (40/60), which was higher than that of CT 91.67% (55/60) (P<0.05). Malignant group, uneven enhanced density, and ascites were higher than the benign group, and the index difference was statistically significant (P<0.05) Malignant tumor diameter and CT value were higher than the benign group (P<0.05). Malignant group, uneven enhanced density, and ascites were higher than the benign group (P<0.05). Conclusions Multilayer spiral CT technology has good value in the differential diagnosis of benign and malignant ovarian cystic gland tumors, which can significantly improve the diagnostic efficiency of ovarian cystic gland tumors.
