磁共振弥散加权成像联合增强扫描对卵巢良恶性囊腺类肿瘤的诊断价值

Diagnostic Value of Magnetic Resonance Diffusion Weighted Imaging Combined with Enhanced Scanning forBenign and Malignant Cystic Glandular Type Tumors of the Ovary

目的:探讨卵巢良恶性囊腺类肿瘤经磁共振弥散加权成像联合增强扫描的诊断价值。方法:选取2018年7月-2022年7月惠州市第六人民医院收治的卵巢良恶性囊腺类肿瘤患者60例为观察对象,经手术及病理最终确诊为卵巢囊腺瘤组49例,交界性卵巢囊腺瘤组6例,卵巢囊腺癌组5例。所有患者接受磁共振弥散加权成像联合增强扫描,分析联合诊断在卵巢良恶性囊腺类肿瘤中的鉴别诊断价值。结果:不同囊腺类肿瘤ADC值比较,差异有统计学意义(P=0.000);卵巢囊腺瘤组弥散受限表现率低于交界性卵巢囊腺瘤组、卵巢囊腺癌组,差异有统计学意义(P<0.05);卵巢囊腺瘤组增强扫描表现明显强化率低于卵巢囊腺癌组,差异有统计学意义(P<0.05);卵巢囊腺瘤组强化并受限率分别低于交界性卵巢囊腺瘤组、卵巢囊腺癌组,差异有统计学意义(P<0.05);卵巢囊腺瘤组无受限无强化率高于交界性卵巢囊腺瘤组、卵巢囊腺癌组,差异有统计学意义(P<0.05)。结论:磁共振弥散加权成像联合增强扫描能有效反映卵巢良恶性囊腺类肿瘤的病理特点,对不同性质肿瘤的诊断及鉴别诊断有重要意义。

Objective:To investigate the diagnostic value of magnetic resonance diffusion weighted imaging combined with enhanced scanning for benign and malignant cystic glandular type tumors of the ovary.Methods:Sixty patients with benign and malignant cystic glandular type tumors of the ovary admitted to Huizhou Sixth People's Hospital from July 2018 to July 2022 were selected as observation subjects.Forty-nine cases were finally diagnosed as ovarian cystic adenoma group,six cases as junctional ovarian cystic adenoma group,and five cases as ovarian cystic adenocarcinoma group after surgery and pathology.All patients underwent magnetic resonance diffusion weighted imaging combined with enhanced scanning to analyze the differential diagnostic value of the combined diagnosis in benign and malignant cystic glandular tumors of the ovary.Results:The ADC values of different cystic glandular tumors were compared with statistically significant differences(P=0.000).The rate of diffusion-limited presentation was lower in the ovarian cystic adenoma group than in the junctional ovarian cystic adenoma group and ovarian cystic adenocarcinoma group,and the difference was statistically significant(P<0.05).The enhanced scanning rate in the ovarian cystic adenoma group was lower than that in the ovarian cystic adenocarcinoma group,and the difference was statistically significant(P<0.05).The rate of enhancement and limitation in the ovarian cystic adenoma group was lower than that in the junctional ovarian cystic adenoma group and ovarian cystic adenocarcinoma group,respectively,and the difference was statistically significant(P<0.05).The rate of unrestricted and unenhanced ovarian cystic adenoma group was higher than that of junctional ovarian cystic adenoma group and ovarian cystic adenocarcinoma group,and the difference was statistically significant(P<0.05).Conclusion:Magnetic resonance diffusion weighted imaging combined with enhanced scanning can effectively reflect the pathological characteristics of benign and malignant cystic glandular tumors of the ovary,which is important for the diagnosis and differential diagnosis of different nature of tumors.
