“CT imaging is painless and super fast,” says radiologist Dr. John Scales. “It produces images so rapidly that it can be used to discover internal injuries, aneurysms and bleeding quickly enough to save lives. It is enormously useful in helping us diagnose and prevent the worsening of a wide variety of problems.”
Nuclear medicine describes a set of painless, noninvasive imaging tests that utilize small amounts of radioactive substances called radiotracers, which are used to diagnose and assess the severity and course of many types of cancers, gastrointestinal disorders, neurological problems, thyroid disease and much more.
