Research Advances on Imaging of Breast Non-Mass Lesions
Non-mass lesions(NML)of the breast are a group of breast lesions lacking special imaging features,which are likely to be missed and misdiagnosed.With the progress of imag-ing technology,clinical attention has been paid to the diagnosis of breast NML in recent years.Malignant breast tumors such as ductal carcinoma in situ,invasive lobular carcinoma,benign lesions such as adenosis and inflammation would present as NML.There are some overlapping imaging features between benign and malignant breast tumors,different imaging methods such as ultrasonography,mammography and magnetic resonance imaging have their own advantages and disadvantages in diagnosis and differential diagnosis of breast NML.It is difficult to identify and distinguish NML by a single imaging examination,while multimodal imaging technology can improve the accuracy of diagnosis and differential diagnosis for breast NML.The research progress on the imaging features and imaging diagnosis of breast NML are reviewed in this paper.
