摘要
目的探讨弥散加权成像(DWI)及其增强扫描在卵巢浆液性囊腺瘤定性及鉴别诊断中的价值。方法选取2017年1月-2018年6月于宁波市鄞州区第二医院肿瘤科经手术病理确诊的82例卵巢浆液性囊腺瘤患者作为研究对象,根据患者手术病理证实其卵巢浆液性囊腺瘤定性进行分组,其中54例良性卵巢浆液性囊腺瘤作为对照组,28例恶性卵巢浆液性囊腺瘤作为观察组,两组患者均行DWI以及动态增强影像学检查,对两组患者实性成分的表观扩散系数(ADC)值进行测量与比较。结果观察组患者DWI高信号例数明显高于对照组,差异具有统计学意义(P<0.05);对照组患者平均ADC值明显高于观察组,差异具有统计学意义(P<0.05);以患者病理结果作为金标准,DWI单项检灵敏度为59.3%,特异度为71.4%,准确度为63.4%,增强单项检查灵敏度为90.7%,特异度为71.4%,准确度为84.2%,DWI联合增强检查灵敏度为96.3%,特异度为82.1%,准确度为91.5%,比较3组诊断方式结果差异具有统计学意义(P<0.05),DWI单项检查与增强单项检查诊断价值明显低于DWI联合增强检查,差异具有统计学意义(P<0.05)。结论DWI联合增强扫描能够定性卵巢浆液性囊腺瘤,并具有良好的鉴别诊断价值,可广泛应用于卵巢浆液性囊腺瘤实性病变的术前诊断。
Objective To explore the value of diffusion weighted imaging(DWI) and enhancement scanning in qualitative analysis and differential diagnosis of ovarian serous cystadenoma. Methods From January 2017 to June 2018,82 patients diagnosed as ovarian serous cystadenoma by surgery and pathological examination in Tumor Department of the Second Hospital of Yinzhou District were selected and divided into control group(54 patients with benign ovarian serous cystadenoma) and observation group(28 patients with malignant ovarian serous cystadenoma). DWI and enhancement scanning were performed in the two groups. Apparent diffusion coefficient(ADC) values in the two groups were measured and compared. Results The number of patients with DWI high signal in observation group was statistically significantly higher than that in control group(P<0. 05);mean ADC value in control group was statistically significantly higher than that in observation group(P < 0. 05). Taking pathological results as gold standard,the sensitivity,specificity,and accuracy of DWI were 59. 3%,71. 4%,and 63. 4%,respectively;the sensitivity,specificity,and accuracy of enhancement scanning were 90. 7%,71. 4%,and 84. 2%,respectively;the sensitivity,specificity,and accuracy of DWI combined with enhancement scanning were 96. 3%,82. 1%,and 91. 5%,respectively. There were statistically significant differences among the three groups(P<0. 05). The diagnostic values of single detection of DWI and enhancement scanning were statistically significantly lower than that of DWI combined with enhancement scanning(P<0. 05).Conclusion DWI and enhancement scanning can qualitatively diagnose ovarian serous cystadenoma,the value of differential diagnosis is high,which can be widely used in preoperative diagnosis of solid lesions in ovarian serous cystadenoma.
