Ch 50 Key Terms Flashcards
A radiologic procedure performed by a radiologist, who uses a contrast medium and fluoroscopy to help diagnose abnormalities or injuries in the cartilage, tendons, or ligaments of the joints—usually the knee or shoulder.
arthrography
A radiologic procedure performed by a radiologist who administers barium sulfate through the anus, into the rectum, and then into the colon to help diagnose and evaluate obstructions, ulcers, polyps, diverticuloses, tumors, or motility problems of the colon or rectum; also called a lower GI (gastrointestinal) series.
barium enema
A radiologic procedure that involves oral administration of a barium sulfate drink to help diagnose and evaluate obstructions, ulcers, polyps, tumors, or motility problems of the esophagus, stomach, duodenum, and small intestine; also called an upper GI (gastrointestinal) series.
barium swallow
A radiation therapy technique in which a radiologist places temporary radioactive implants close to or directly into cancerous tissue; used for treating localized cancers.
brachytherapy
A test that evaluates the function of the bile ducts by injection of a contrast medium directly into the common bile duct (during gallbladder surgery) or through a T-tube (after gallbladder surgery or during radiologic testing) and taking an X-ray.
cholangiography
A substance that makes internal organs denser and blocks the passage of X-rays to photographic film. Introducing a contrast medium into certain structures or areas of the body can provide a clear image of organs and tissues and highlight indications of how well they are functioning.
contrast medium
The use of X-ray technology to determine the cause of a patient’s symptoms.
diagnostic radiology
A screening test that uses small doses of X-rays to determine the mineral density of a person’s bones; also called bone densitometry.
dual-energy X-ray absorptiometry
A radiologic procedure in which the doctor injects a contrast medium into a vein and takes a series of X-rays of the kidneys, ureters, and bladder to evaluate urinary system abnormalities or trauma to the urinary system; also known as excretory urography.
intravenous pyelography
Referring to a procedure in which a catheter, wire, or other foreign object is introduced into a blood vessel or organ through the skin or a body orifice. Surgical asepsis is required during all invasive tests.
invasive
The process of X-raying the abdomen to help assess the size, shape, and position of the urinary organs; evaluate urinary system diseases or disorders; or determine the presence of kidney stones. It also can be helpful in determining the position of an intrauterine device (IUD) or in locating foreign bodies in the digestive tract; also called a flat plate of the abdomen.
KUB radiography
X-ray examination of the breasts.
mammography
A radiologic procedure that evaluates the condition of the heart’s myocardium; it involves injection of radioisotopes that concentrate in the myocardium, followed by the use of a gamma camera to measure ventricular contractions to evaluate the patient’s heart wall.
MUGA scan
An X-ray visualization of the spinal cord after the injection of a radioactive contrast medium or air into the spinal subarachnoid space (between the second and innermost of three membranes that cover the spinal cord). This test can reveal tumors, cysts, spinal stenosis, or herniated disks.
myelography
Referring to procedures that do not require inserting devices, breaking the skin, or monitoring to the degree needed with invasive procedures.
noninvasive
