x-rays are directed through the body to a fluorescent screen that displays continuous motion images of internal structures
magnetic resonance imaging
uses radiowaves and a strong magnetic field rather than an x-ray beam to produce multiplanar cross-sectional images
uses a radioactive material called a tracer that is introduced into the body and a specialized camera to produce images of organs and structures
position emission tomography
using computed tomography to record the positrons emitted from a radiopharmaceutical, that produces a cross-sectional image of metabolic activity in body tissues to determine the presence of disease
integrates computed tomography and a radioactive material injected into the bloodstream to visualize blood flow to tissues and organs
produces an image representing a detailed cross-section of an area, tissue, or organ at a predetermined depth

incision and drainage
incision made to allow the free flow or withdrawal of luids from a wound or cavity
employing a device that emits intense heat and power at close range to cut, burn, vaporize, or destroy tissues
