X rays and Diagnostic Radiology Introduction Diagnostic radiology is a valuable tool for physicians for screening and clinical diagnosis. Safety issues, proper handling, and storage of the actual films are discussed. You will learn the basics of noninvasive and invasive radiology and your role in this testing. Brief History of X ray 1895 - Wilhelm K Roentgen discovered X ray. High energy level of electromagnetic waves traveling at 186,000 miles per second that can penetrate solids. X ray reacts with photographic film. Diagnostic Radiology Tests sometimes use contrast media. Special techniques or instruments for viewing internal structures and functions. Contrast medium – Substance that makes internal organs denser Blocks the passage of X -rays to the photographic film Contrast media include gases, heavy metal salts (barium sulfate or bismuth carbonate), and iodine compounds. Invasive Procedures Requires a radiologist to insert a catheter, wire, or other testing device into a blood vessel or organ Requires surgical aseptic techniques For example, Angiography Noninvasive Procedures Standard X rays or ultrasound View .
