“X-rays were discovered in 1895 by Wilhelm Roentgen, a professor who was working on emissions from electric currents in vacuums. While working, he discovered a glow from the barium platinocyanide coated screen. He continued to experiment and landed the first Nobel Prize in Physics in 1901” (Bansal, 2006). Over the years, many improvements have been made to Roentgen’s discovery and radiography is offered in every hospital around the world.
Nowadays, there are many different types of imaging we can do. These include fluoroscopy, CT scan, nuclear medicine, and ultrasound. Fluoroscopy’s significant use is it intensifies the image during orthopedic, vascular, urological procedures. It is also used for dynamic radiographic investigations. “CT is useful for evaluating soft tissue involvement of lesions or determining the extent of fractures. In general, CT is useful to add to the anatomic or pathologic information already obtained by conventional radiography” (Bontrager & Lampignano, 2010). “Nuclear medicine is more sensitive and generally provides earlier evidence than other modalities because it assesses the physiologic aspect rather than the anatomic aspect of these conditions. Nuclear medicine uses very small amounts of radioactive materials to diagnose and treat disease” (Nuclear Medicine, 2013). “Ultrasound can be used in several different ways such as monitoring an unborn baby, diagnosing a condition or guiding a surgeon during certain procedures by using sound waves” (Ultrasound, 2011).
An important change came about with the development and common use of computer technology. “Such use of a filmless radiology department was very interesting to this medical field. Digital radiography was introduced in the mid 1980’s and now competes with screen film radiography in all radiographic applications” (Bansal, 2006).
Radiographs are essentially used for the diagnosis of many different diseases and injuries. “They have many different advantages such as their low cost, for the most part non-invasive nature, easy availability, relatively harmless, and fast imaging times. Put all this together with a clear, perfectly contrasted image it is no wonder why we use it” (Bansal, 2006).
Screen film radiography is still used more commonly than digital radiography. “Although there is a declining of popularity of screen film radiography mainly because there is limited potential for reducing dose to the patient. Also, unlike digital radiography, images cannot be changed in contrast once they have been processed. In screen film radiography, film is expensive, uses hazardous materials for processing, is very strenuous and long term storage is difficult. Lastly, screen film radiography is not compatible with the picture archiving and communication systems also known as PACS” (Bansal, 2006).
