We examined 14 benign and 26 malignant breast nodules by a handheld dual-modal PA/US imaging system and analyzed the data using the quantitative and semi-quantitative method. The and PA scores of different regions of the benign and malignant nodules were compared, and the diagnostic performances of two diagnostic methods based on PA parameters were evaluated. For both quantitative and semi-quantitative results, significant differences in the distributions of PA signals in different regions of benign and malignant breast lesions were identified. The PA parameters showed good performance in diagnosing breast cancer, indicating the potential of PAI in clinical utilization.
我们使用手持式双模态光声/超声成像系统对14个良性和26个恶性乳腺结节进行了检查,并采用定量和半定量方法对数据进行了分析。比较了良性和恶性结节不同区域的光声和超声评分,并评估了基于光声参数的两种诊断方法的诊断性能。对于定量和半定量结果,均发现良性和恶性乳腺病变不同区域的光声信号分布存在显著差异。光声参数在乳腺癌诊断中表现良好,表明光声成像在临床应用中的潜力。
