Study offers updated guidelines on useof breast MR imaging
Surgical decisions should not be based solely on MRI findings because not all suspicious lesions on MRI are cancer, and suspicious lesions should be biopsied before a surgical plan is devised in order to avoid surgical overtreatment, according to guidelines published in the Journal of the National Comprehensive Cancer Network.
Surgical decisions should not be based solely on MRI findings because not all suspicious lesions on MRI are cancer, and suspicious lesions should be biopsied before a surgical plan is devised in order to avoid surgical overtreatment, according to guidelines published in the Journal of the National Comprehensive Cancer Network.
Among the recommendations is that MRI is not a substitute for screening or diagnostic mammography and, when indicated, diagnostic breast ultrasound, the guidelines state. But when cancer is found in the lymph nodes but not the breast, MRI can find the location of cancer in the breast in nearly 60% of women.
The guidelines were developed by Dr. Constance Lehman, a professor of radiology at the University of Washington and director of breast imaging at Seattle Cancer Care Alliance, and colleagues. They were based on an extensive review of published, peerreviewed studies.
New MRI Research Explores Links Between Waist-to-Hip Ratio and Memory in Aging
March 13th 2025Researchers found that a higher waist-to-hip ratio in midlife was associated with higher mean diffusivity in 26 percent of total white matter tracts in the cingulum as well as the superior and inferior longitudinal fasciculus.
Can Ultrasound-Based Radiomics Enhance Differentiation of HER2 Breast Cancer?
March 11th 2025Multicenter research revealed that a combined model of clinical factors and ultrasound-based radiomics exhibited greater than a 23 percent higher per patient-level accuracy rate for identifying HER2 breast cancer than a clinical model.
