-
adhesion
band of scar tissue binding anatomical surfaces that are normally separate from each other
-
inflammation
protective response of body tissues to irritation, infection, or allergy
-
sepsis
body's inflammatory response to infection in which there is fever, elevated heart and respiratory rate, and low blood pressure
-
endoscopy
visual examination of the interior of organs and cavities with a specialized lighted instrument called an endoscope
-
fluoroscopy
radiographic procedure that uses a fluorescent screen instead of a photographic plate to produce a visual image from x-rays that pass through the patient, resulting in continuous imaging of the motion of internal structures and immediate serial images
-
tomography
radiographic technique that produces a film representing a detailed cross-section of tissue structure at a predetermined depth
-
computed tomography (CT) scan
narrow beam of x-rays with a contrast medium (provides more detail) or without a contrast medium that targets a specific organ or body area to produce multiple cross-sectional images for detecting such pathological conditions as tumors or metastases
-
positron emission tomography (PET) scan
nuclear imaging study that combines CT with radiopharmaceuticals to produce a cross-sectional image of radioactive disperrsements in a section of the body to reveal the areas where the radiopharmaceutical is being metabolized and where there is a deficiency in metabolism; useful in evaluating Alzheimer disease and epilepsy
-
single-photon emission computed tomography (SPECT) scan
nuclear imaging study that scans organs after injection of a radioactive tracer and employs a specialized gamma camera that detects emitted radiotion to produce a 3-dimensional image from a composite of numerous views; used to show how blood flows to an organ and helps determine how well it is functioning
-
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 internal organ or tissue
-
anterior
toward the front of the body, organ, or structure
-
anteroposterior
pertaining to the front and back fo the body or passing from the front to the back of the body
-
inferior
pertaining to below, lower, or toward the tail
-
scan
process of using a moving device or a sweeping beam of radiation to produce images of an internal area, organ, or tissue of the body
