目的探讨PET/CT在卵巢良恶性及交界性肿瘤诊断中临床应用价值。方法对2009年至2011年采用手术或者病理学确证的34例卵巢良恶性及交界性肿瘤患者的临床资料进行回顾性分析。结果本组34例患者经PET/CT检测证实卵巢良性肿块17例,肿瘤直径为3～22cm;恶性肿瘤15例,肿瘤直径为2～30cm;交界性肿瘤2例,肿瘤直径为4～6cm。PET/CT和常规影像学检查在临床诊断准确性方面比较无显著性差异(P>0.05)。与常规影像学检查相比,PET/CT的临床诊断灵敏度显著性较高(P<0.05),特异性、准确性、阳性预测值和阴性预测值两组比较无显著性差异(P>0.05)。结论 PET/CT对于妇科卵巢良恶性肿瘤以及交界性肿瘤具有重要的诊断意义,值得临床推广使用。
Objective To investigate the clinical value of PET / CT in the diagnosis of benign and malignant ovarian tumors and borderline tumors. Methods The clinical data of 34 patients with benign and malignant ovarian tumors who had surgically or pathologically confirmed ovarian lesions from 2009 to 2011 were analyzed retrospectively. Results The 34 cases of benign ovarian tumors were confirmed by PET / CT in 17 cases. The diameter of the tumor was 3 ~ 22 cm. The malignant tumors were 15 and the diameter of the tumor was 2 ~ 30 cm. The borderline tumors were 2 and the diameter of the tumor was 4 ~ 6 cm. There was no significant difference in the accuracy of clinical diagnosis between PET / CT and conventional imaging (P> 0.05). The diagnostic sensitivity of PET / CT was significantly higher than that of conventional imaging (P <0.05), and the specificity, accuracy, positive predictive value and negative predictive value had no significant difference (P> 0.05) . Conclusion PET / CT has important diagnostic value for benign and malignant tumors of gynecologic ovary as well as borderline tumors and is worthy of clinical application.
