Presentation on theme: "Module 2 Body Structure. Smallest to largest structures Location of structures Position of structures in reference to each other How we visualize structures."— Presentation transcript:
Scan: Scan: Technique for carefully studying an area, organ or system by recording and displaying multiple images of the area. Ultrasonography (US): Ultrasonography (US): Imaging technique that uses high-frequency sound waves, ultrasound, that bounce off body tissues and are recorded to produce an image of an organ or tissue. Radiography: Production of captured shadow images on photographic film through the action of ionizing radiation passing through the body from an external source.
Fluoroscopy: Fluoroscopy: Radiographic procedure that uses a fluorescent screen instead of a photographic plate. Radiopharmaceutical: Radiopharmaceutical: Drug that contains a radioactive substance that travels to an area or a specific organ that will be scanned. Nuclear Scan: Diagnostic technique that produces an image by recording the concentration of a radiopharmaceutical called a radionuclide which is detected by a scanning device.
Tomography: Tomography: Any technique that produces a film representing a detailed cross section of tissue structure at a predetermined depth. Computed Tomography (CT): Computed Tomography (CT): Radiographic technique that uses a narrow beam of x- rays, rotating in a full arc around the patient to image the body in cross sectional slices. Magnetic Resonance Imaging (MRI): Radiographic techniques that use electromagnetic energy to produce cross- sectional images of the body at many planes.
Positron Emission Tomography (PET):. Good for disorders like stroke, epilepsy and Alzheimer's. Positron Emission Tomography (PET): Radiographic technique which combines computed tomography and the use of radiopharmaceuticals (radioactively labeled drugs). Good for disorders like stroke, epilepsy and Alzheimer's. Single-Photon Emission Computed Tomorgraphy (SPECT): Single-Photon Emission Computed Tomorgraphy (SPECT): Type of nuclear imaging study to scan organs after an injection of a radioactive tracer. Like PET scan but typically produces 3D images. Endoscopy: visual examination of interior of organs using a specialized lighted instrument called an endoscope.
Adhesion: Adhesion: Band of scar tissue binding surfaces that are normally separate from each other. Anastomosis: Anastomosis: 1. Connection between two blood vessels or 2. Surgical joining of two ducts, vessels or bowel segments. Cauterize: Process of burning tissue by thermal heat, electricity, laser, or dry ice.
Inflammation: Inflammation: Protective response of body tissues to infection or allergy. Signs include: Sepsis: Sepsis: Inflammatory response to infection characterized by fever, elevated heart and respiratory rate and low blood pressure.
