常规超声、超声弹性成像以及18F-FDG PET/CT诊断乳腺良恶性病变的价值

目的观察常规超声、超声弹性成像以及¹⁸F-FDG PET/CT对乳腺良恶性病变的诊断价值。方法回顾性2019年1月至2020年2月在我院治疗的67例乳腺病变患者的临床资料。分析其影像学资料,比较常规超声、超声弹性成像以及¹⁸F-FDG PET/CT检查结果与病理学检查结果的一致性;以病理学检查为标准,比较三种检查对乳腺良恶性病变的诊断效能及诊断价值。结果¹⁸F-FDG PET/CT检查结果与病理学检查结果的一致性(Kappa=0.906)大于常规超声(Kappa=0.566)和超声弹性成像(Kappa=0.662);¹⁸F-FDG PET/CT鉴别乳腺良恶性病变的灵敏度及特异度高于常规超声,准确率高于常规超声、超声弹性成像(P<0.05);经ROC曲线分析得,¹⁸F-FDG PET/CT鉴别乳腺良恶性病变的AUC为0.966,大于常规超声(0.787)及超声弹性成像(0.838,P<0.05)。结论¹⁸F-FDG PET/CT鉴别乳腺良恶性病变的准确率高于常规超声、超声弹性成像,且其具有较高的诊断价值。

Diagnostic Value of Routine Ultrasound,Ultrasonic Elastography,and 18F-FDG PET/CT in Benign and Malignant Breast Lesions

Objective To observe the diagnostic value of routine ultrasound,ultrasonic elastography(UE)and ¹⁸F-FDG PET/CT in benign and malignant breast lesions.Methods The clinical data of 67 patients with breast lesions who were treated in the hospital from January 2019 to February 2020 were retrospectively analyzed.Their imaging data were analyzed.The consistencies between routine ultrasound,UE and ¹⁸F-FDG PET/CT examination results and pathological examination results were compared.Taking pathological examination as the standard,diagnostic efficiency and diagnostic value of the three examination methods for benign and malignant breast lesions were compared.Results The consistency between ¹⁸F-FDG PET/CT and pathological examination results was higher than that between routine ultrasound and pathological examination results and between UE and pathological examination results(Kappa:0.906 vs.0.566,0.662).The sensitivity and specificity of ¹⁸F-FDG PET/CT for identifying benign and malignant breast lesions were higher those of routine ultrasound.And its accuracy was higher than that of routine ultrasound and UE(P<0.05).ROC curve analysis showed that the AUC of ¹⁸F-FDG PET/CT for identifying benign and malignant breast lesions was greater than that of routine ultrasound and UE(0.966 vs.0.787,0.838)(P<0.05).Conclusion The accuracy of ¹⁸F-FDG PET/CT is higher than that of routine ultrasound and UE for identifying benign and malignant breast lesions,which is of high diagnostic value.
