What would Wilhelm Roentgen, the father of X-ray, say about the technological discoveries in radiology today? Since the start of X-rays in 1895 significant advancements have revolutionized the field of radiology. One illustrates how different scanners have improved, in addition how picture archiving communication system can assist doctors, and finally the outlook on the future of radiology.






To begin with, how has technology changed the field of radiology? Since the discovery of X-radiation there has been a need and desire for studying the human body and the diseases without actually any intervention. Over the past fifty years there has been a revolution in the field of radiology affecting medicine profoundly. “The ability to produce computers powerful enough to reconstruct accurate body images, yet small enough to fit comfortably in the radiology department, has been the major key to this progress”(Gerson 66). The core of radiology’s vast development consists of four diagnostic techniques: computed tomography (CT), digital subtraction angiography (DSA), ultrasonography, and magnetic resonance imaging (MRI). These methods of diagnostic imaging provide accurate information that was not seen before. Amid this information advancement, radiologists have broadened their role of diagnostician. Gerson writes, “With the advent of computer-enhanced imagery and new interventional techniques, these physicians are able to take an active part in performing therapeutic procedures”(66). A radiology breakthrough in 1972 was computed tomography discovered by Godfrey Hounsfield and Allan Cormack. Unlike standard radiography, computed tomography would spin the X-ray tube 360 degrees and inversely another 360 degrees while the patient ta...

MRI: An Advancement in Technology Essay

- One of the most recently new advances in radiology is the use of magnetic resonance imaging (MRI). MRI has been around for the past century. It was at first called Nuclear Magnetic Resonance (NMR) and then it changed to MRI once there was an available image. Walter Gerlach and Otto Stern were the first scientists to start experimenting with the magnetic imaging. Their very first experiment was looking at the magnetic moments of silver by using some type of x-ray beam. The scientists then discovered this was by realizing that the magnetic force in the equipment and in the object itself....   [tags: patients, diagnos, medical]
