Methods and Materials
From June 2010 to December 2011,
169 patients with 195 breast lesions,
of which 125 were breast cancers and 70 were benign lesions verified by surgical pathology,
were examined by PI,
mammography and ultrasound in cancer hospital,
Chinese Academy of Medical Sciences.
and mobility of the lesion extracted from PI were used for lesion characterization.
To compare diagnostic performance of a test for the features characterizing the lesion,
we use the receiver operating characteristics (ROC) curve analysis and evaluate PI for differentiation between benign and malignant lesions.
Additional diagnostic information provided by other diagnostic modalities was collected and used for the analysis of the potential of diagnosis of breast lesion by PI.
The diagnostic sensitivity and specificity of the four examinations were compared.In addition,
the sensitivity and specificity of PI for patients with different breast composition on mammography were calculated.
