When women undergo breast imaging shortly after receiving a COVID-19 vaccine in the arm, their tests may show swollen lymph nodes in the armpit area. Radiologists at Massachusetts General Hospital say that this is usually a normal finding, and if there are no other concerns, no additional imaging tests are needed unless the lymph nodes remain swollen for more than six weeks after vaccination. The team has published an approach to help avoid delays in both vaccinations and breast cancer screening.
An open-access article in ARRS' American Journal of Roentgenology (AJR) describes the clinical and imaging features of axillary adenopathy detected during screening or diagnostic breast imaging after recent coronavirus disease (COVID-19) vaccination to inform the development of follow-up recommendations.
Researchers have discovered a blood biomarker that predicts kidney transplant rejection with a lead time of about eight months, which could give doctors an opportunity to intervene and prevent permanent damage, potentially using an existing medication.
A team of engineers has identified the 'violent' physical processes at work inside the lungs which cause wheezing, a condition which affects up to a quarter of the world's population.
A complete blood count can help ascertain the health of a patient and typically includes an estimate of the hemoglobin concentration, which can indicate several conditions, including anemia, polycythemia, and pulmonary fibrosis. In AIP Advances, researchers describe a AI-powered imaging-based tool to estimate hemoglobin levels. The setup was developed in conjunction with a microfluidic chip and an AI-powered automated microscope that was designed for deriving the total as well as differential counts of blood cells.
A machine learning algorithm helps accurately differentiate benign and premalignant colorectal polyps on CT colonography scans, according to a new study.
A team of researchers at Beth Israel Deaconess Medical Center (BIDMC) has developed a mathematical means of assessing tests' false-negative rate.
With the onset of the COVID-19 pandemic, telemedicine has become a new norm for many routine and non-emergency medical needs. But there are lessons to be learned from telemedicine's use - or lack thereof - prior to the pandemic, and a new study from a UConn School of Social Work researcher offers insight for policymakers, administrators, and public health officials when considering the implementation of new services.
A study carried out at the University of Helsinki investigated pituitary dwarfism in Karelian Bear Dogs and found a link to a variant of the POU1F1 gene. The results can also help understand the gene's significance to the human pituitary gland's development and function.
The finding may help identify women at high risk and enable early therapeutic interventions to prevent heart disease from developing.
