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 lightened instrument called an endoscope
fluoroscopy (radiographic procedure) uses fluorescent screen to produce a visual image from x-rays. produces a continuous imaging of the motion of internal structures and immediate serial images
magnetic resonance imaging (MRI) (radiographic technique) uses electromagnetic energy to produce multiplanar cross-sectional images of the body
nuclear scan (diagnostic technique) produces image of an organ or area by recording the concentration of a tracer (is put into body by ingestion, inhalation)
radiography producing captured shadow images on a photographic film through action of ionizing radiation passing through the body from an external source
radiopharmaceutical drug that contains a radioactive substance. It travels to an area or a specific organ that will be scanned
tomography (radiographic technique) produces film representing a detailed cross-section of tissue structure at t predetermined depth
computed tomography scan (CT) narrow x-rays beam, targets a specific organ or body area, produces lots of cross-sectional images to deter pathological conditions such as tumors or metastases
positron emission tomography scan (PET) (nuclear imaging) combines CT with radiopharmaceuticals to produce a cross-sectional image of radioactive dispersements in a body section. These reveal where body is metabolized and where there is a metabolism deficiency. in Alzheimer disease, epilepsy
single-photon emmission computed tomography scan (SPECT) (nuclear imaging) scans organs after radioactive tracer injection. employs a gamma camera that detects emitted radiation to produce 3d images from numerous views. Used for blood flow and functioning in organs
