Flashcards in Diseases and Conditions and Diagnostic Procedures (Body) Deck (16):


Band of scar tissue binding anatomical surfaces that are normally separate from each other.



Protective response of body tissues to irritation, infection, or allergy



Body's inflammatory response to infection in which there is fever, elevated heart and respiratory rates, and low blood pressure.



Visual examination of the interior of organs and cavities with a specialized lighted instrument called an "endoscope"
[endo= in, within; -scopy=visual examination]



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.
[fluor/o=luminous, fluorescence; -scopy=visual examination]


Magnetic Resonance Imaging (MRI)

Radiographic technique that uses electromagnetic energy to produce multiplanar cross-sectional images of the body.


Nuclear Scan

Diagnostic technique that produces an image of an organ or area by recording the concentration of a radiopharmaceutical substance called a "tracer" usually introduced into the body by ingestion, inhalation, or injection



Production of captured shadow images on photographic film through the action of ionizing radiation passing through the body from an external source.
[radi/o=radiation, x-Ray; radius (lower arm bone on the thumb side); -graphy=process of recording]



Drug that contains a radioactive substance, which travels to an area or a specific organ that will be scanned
[radi/o= radiation, x-Ray; radius (lower arm bone on thumb side); pharmaceutical=drug, medicine; -al=pertaining to]



Radiographic technique that produces a film representing a detailed cross-section of tissue structure at a predetermined depth
[tom/o=to cut; -graphy=process of recording]


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 pathological conditions such as tumors or metastasis.
[tom/o=to cut; -graphy= process of recording]


Positron Emission Tomography (PET) Scan

Nuclear imaging study that combines CT with radiopharmaceuticals to produce a cross-sectional image of radioactive dispersement 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's disease and epilepsy.
[tom/o=to cut; -graphy=process of recording]


Single-Photon Emission Computed Tomography (SPECT) Scan

Nuclear imaging study that scans organs after injections of a radioactive tracer and employs a specialized gamma camera that detects emitted radiation to produce a three-dimensional image from a composite of numerous views; used to show how blood flows to an organ and helps determine how well the organ is functioning.
[tom/o=to cut; -graphy=process of recording]


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.
[-ultra=excess, beyond; son/o=sound; -graphy=process of recording]


Basal Cell Carcinoma (BCC)

most common form of skin cancer, caused by overexposure to sunlight. Nonmelanoma skin cancer that is a malignancy of the basal layer of the epidermis, or hair follicles. Rarely spreads to other parts of the body (metastazie). Prominent in blond, fair-skinned men. most common malignant tumor affecting white people. treatment includes surgical excision, curettage and electrodesiccation, cryosurgery, radiation therapy.


Squamous Cell Carcinoma (SCC)

second most common form of nonmelanoma skin cancer. Due to prolonged exposure to ultraviolet (UV) radiation, either from sunlight or from tanning beds/lamps. Sunscreen is important but does not completely prevent SCC. Rarely causes further problems when treated early. Untreated can metastasize causing serious complications.
