Q

Fluoroscopy

A

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]

Q

Computed Tomography (CT) Scan

A

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]

Q

Positron Emission Tomography (PET) Scan

A

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]

Q

Single-Photon Emission Computed Tomography (SPECT) Scan

A

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.

Ultrasonography (US)

A

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.

Q

Basal Cell Carcinoma (BCC)

A

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.

Q

Squamous Cell Carcinoma (SCC)

A

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.
