Radiology professionals today can do more than just look at X-Rays. They have a window into the human body with technologies like magnetic resonance imaging, positron emission tomography, and computed tomography, among many modalities. The technology that drives accurate and consistent medical imaging has grown and improved steadily, making it easier for radiology professionals to identify the correct diagnoses. Research dollars have been poured into methods for non-invasive, early discovery of a host of diseases, including cancer, stroke, and cardiovascular system conditions like artery blockages.
