With the increasing use of breast conservation therapy for breast cancer, reports of postirradiation angiosarcoma have increased. Both primary and secondary angiosarcomas may present with bruiselike skin discoloration, which may delay the diagnosis. Imaging findings are nonspecific. MRI may be used to determine lesion extent by showing rapid enhancement and washout in high-grade tumors

Doubling physician annual volume requirements would result in a small impact on overall mammography capacity. Increasing volume requirements to 2,000 mammography examinations annually would require a dramatic increase in the number of mammography examinations interpreted by the higher volume radiologists. Unless previously low-volume radiologists increased their volumes, raising requirements to 2,000 examinations could curtail access to mammography, particularly in rural areas

Our results showed that differences exist in the sonographic features of screening-detected and symptomatic DCIS. Recognition of the many and varied sonographic appearances of DCIS might be helpful to decrease the false-negative rate of bilateral whole-breast sonography and to detect symptomatic mammographically occult DCIS when we use sonography to supplement mammography

Lesion and Patient Characteristics Associated with Malignancy After a Probably Benign Finding on Community Practice Mammography

In community practice, patient and lesion mammographic characteristics can be predictive of the likelihood of a subsequent cancer diagnosis of mammographic lesions designated as probably benign. Careful evaluation of mass margins and of the morphologic features of calcifications can help distinguish a malignant lesion from a probably benign finding

Correlation of Whole-Breast Vascularity with Ipsilateral Breast Cancers Using Contrast-Enhanced MDCT

Breast cancers were found to be associated with ipsilateral increased whole-breast vascularity in a significant percentage of patients. Increased whole-breast vascularity indicated the growth and metastatic potential of a breast cancer

Role of Sonography in the Detection of Contralateral Metachronous Breast Cancer in an Asian Population

Sonography alone detected 14% of metachronous contralateral breast cancers. The results of this study suggest that annual additional sonography with mammography contributes to the early detection of metachronous cancers. However, sonography every 6 months is unlikely to be helpful for the early detection of metachronous cancer
