Researchers from the McKelvey School of Engineering and Washington University School of Medicine in St. Louis are one step closer to delivering precise amounts of medication to exact location, repurposing an existing imaging “painting” method.
Hong Chen, assistant professor of biomedical engineering in the School of Engineering & Applied Science and assistant professor of radiation oncology at the School of Medicine, reached across disciplines to work toward a more focused drug delivery system that could target tumors lodged in the brainstem, the body’s most precious system.
Children suspected of having appendicitis are more likely to receive CT scans, which involve radiation, if they are evaluated at a general hospital, a new study by Washington University School of Medicine in St. Louis has shown.
Scientists have combined two existing forms of medical imaging — photoacoustic and ultrasound — to generate high-contrast, high-resolution images that could help doctors spot tumors more quickly.
Adding ultrasound exams to annual breast cancer screening can detect more cancers in women who have dense breasts and are at a higher risk of breast cancer, according to a three-year, multi-center trial appearing this week in the Journal of the American Medical Association. But the scans carry risks that may outweigh their benefits.
