Diagnostic Value of Ultrasound and Ultrasound-guided Fine Needle Aspiration Cytology in Palpation Negative Nodules in Breast Screening
Objective To analyze the diagnostic value of ultrasound and ultrasound-guided fine needle aspiration cytology in palpation negative nodules in breast screening.Methods From June 2020 to May 2024,100 patients with negative palpation nodules in breast screening in Xinyu Yushui District Maternal and Child Health Hospital were selected as the research objects.All the subjects were diagnosed by ultrasound and ultrasound-guided fine needle aspiration cytology.At the same time,the results of surgical pathological biopsy were taken as the gold standard,and the diagnostic results were recorded.The value of the two methods in the diagnosis of benign and malignant breast nodules with negative palpation was compared.Results Postoperative histopathological biopsy results showed that among the 100 patients,there were 20 patients with benign lesions and 80 patients with malignant lesions.The results of ultrasound-guided fine needle aspiration cytology showed that 74.07%of BI-RADS 4a breast masses were malignant masses,35.29%of BI-RADS 4b breast masses were malignant masses,96.43%of BI-RADS 4c breast masses were malignant masses,the specificity,sensitivity,positive predictive value,negative predictive value and diagnostic accuracy of ultrasound-guided fine needle aspiration cytology were higher than those of conventional ultrasound(P<0.05).Conclusion In the diagnosis of palpable negative breast nodules,the diagnosis of ultrasound and ultrasound-guided fine needle aspiration cytology has the characteristics of high accuracy,high sensitivity and high specificity.It is helpful for early clinical diagnosis and can assist doctors to observe the lesions.It has high diagnostic value and is worthy of clinical application.
