Chicago—While imaging technologies such as magnetic resonance imaging and computed tomography are enormously helpful noninvasive aids for diagnosing and monitoring various medical conditions, such methods have considerable limitations. However, explained scientists describing their research at the Clinical Congress of the American College of Surgeons in October, tiny implantable devices capable of sensing such elements as changes in pressure within a weakened blood vessel or the load borne by an artificial disk in the spine may someday help clinicians treat a variety of vascular and orthopedic problems.
