Intro to Radiology

Definitions X ray 1. an electromagnetic wave of high energy and very short wavelength, which is able to pass through many materials opaque to light. a photographic or digital image of the internal composition of something, especially part of the body, produced by X-rays being passed through it and being absorbed to different degrees by different materials. https: //www. google. com/webhp? sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=define%20 exray

CT Computerized axial tomography scan: Pictures of structures within the body created by a computer that takes the data from multiple X-ray images and turns them in pictures. The CAT (computerized axial tomography) scan reveal some soft-tissue and other structures that cannot be seen in conventional X-rays. Using the same dosage of radiation as that of an ordinary X-ray machine, an entire slice of the body can be made visible with about 100 times more clarity with the CAT scan. http: //www. medicinenet. com/script/main/art. asp? articlekey=10353

Ultra sound the use of high-frequency sound (several MHz or more) to image internal structures by the differing reflection signals produced when a beam of sound waves is projected into the body and bounces back at interfaces between those structures. Ultrasound diagnosis differs from radiological diagnosis in that there is no ionizing radiation involved. Also called ultrasound diagnosing. For Mosby's Medical Dictionary: ultrasound imaging.

MRI a noninvasive medical diagnostic technique in which the absorption and transmission of highfrequency radio waves are analyzed as they irradiate the hydrogen atoms in water molecules and other tissue placed in a strong magnetic field. This computerized analysis provides a powerful aid to the diagnosis and treatment planning of many diseases, including cancer. http: //www. thefreedictionary. com/magnetic+resonance+imaging
