摘要: Abstract This study aimed to assess the potential of state-of-the-art ultrasound analysis techniques non-invasively diagnose axillary lymph nodes involvement in breast cancer. After exclusion criteria, 105 patients were selected from two different hospitals. The 118 node images taken these divided into 53 cases and 65 controls, which made up series. clinical outcome each was verified by ultrasound-guided fine needle aspiration, core biopsy or surgical biopsy. achieved accuracy proposed method 86.4%, with 84.9% sensitivity 87.7% specificity. When tested on cancer only, improved sonographic assessment performed expert radiologists 9% (87.0% vs 77.9%). In conclusion, results demonstrate image detect microstructural compositional changes that occur because metastatic involvement.
