Swollen lymph nodes after vaccination? Fear not
June 15, 2021 -- Swollen lymph nodes developed in breast imaging patients in Israel shortly after they received COVID-19 vaccines, but that may not be reason to worry, according to research published June 10 in Academic Radiology. Read More
High BPE on breast MRI linked to BRCA gene mutation for breast cancer
June 15, 2021 -- Background parenchymal enhancement (BPE) on breast MRI has already been linked to breast cancer risk in women undergoing mammograms. Now, a new study has found a connection between BPE and genetic mutations that are indicators of higher breast cancer risk. Read More
Animal study suggests Ga-68 PET FAPI can detect lung fibrosis
June 14, 2021 -- PET imaging with a gallium-68 (Ga-68)-labeled fibroblast activation protein inhibitor (FAPI) shows promise as an effective way to identify and monitor pulmonary fibrosis, according to animal study findings presented at the virtual 2021 Society of Nuclear Medicine and Molecular Imaging annual meeting.
