Engineers at the Johns Hopkins Urology Robotics Lab report the invention of a motor without metal or electricity that can safely power remote-controlled robotic medical devices used for cancer biopsies and therapies guided by magnetic resonance imaging.
University of Cincinnati neuroradiologists believe a brain imaging approach that combines standard magnetic resonance imaging scans with specialized contrast-enhanced techniques could lead to more effective diagnoses in patients with difficult-to-detect blood clots in veins of the brain.
As the diagnostic capability of MRI continues to advance, and as the availability of MRI machines increases worldwide, so should the availability of implantable devices that are MRI safe. This advance is urgently needed says one executive.
Researchers have called for a national database to be set up to identify major complications arising from epidural pain relief after a small number of serious problems were identified during a six-year UK study, according to the April issue of Anaesthesia.
Up to 10 percent of women newly diagnosed with cancer in one breast develop cancer in the opposite breast. Results of a major clinical trial show that magnetic resonance imaging (MRI) scans are highly effective tools for quickly identifying these opposite breast cancers, detecting diseased tissue that other screening methods missed.
Researchers at Melbourne?s Howard Florey Institute have opened up new treatment possibilities for Huntington?s disease by proving a scientific theory incorrect.
Researchers at UC San Diego have discovered that iron-containing nanoparticles being tested for use in several biomedical applications can be toxic to nerve cells and interfere with the formation of their signal-transmitting extensions.
Women who have been diagnosed with breast cancer in one breast have a higher risk of contracting the disease in their opposite breast as well. A thorough examination of the opposite breast using mammography and ultrasound is therefore common practice.
Women with a recent diagnosis of cancer in one breast should have MRI screening of the opposite breast, concludes a multi-center study involving University of North Carolina at Chapel Hill researchers.
Heart problems in children are quite different from those in adults, and four studies presented today at the American College of Cardiology?s 56th Annual Scientific Session look at how pediatric cardiologists take different approaches to better understand and manage cardiovascular disease in this population, including insights into fundamental cardiac mechanisms and testing of new procedures.
