Question 1: interventional radiology

Answer:

therapeutic procedures performed by a radiologist

Question 2: computed tomography (CT)

Answer:

diagnostic x-ray procedure whereby a cross-sectional image of a specific body segment body segment is produced

Question 3: ultrasonography (US, U/S)

Answer:

diagnostic technique that projects and retrieves high-frequency sound waves as they echo off parts of the body

Question 4: radioisotope

Answer:

radioactive form of an element substance; radionuclide

Question 5: scan

Answer:

image of an area, organ or tissue in the body obtained from ultrasound, radioactive tracer studies, CT, or MRI

Question 6: single photon emission computed tomography (SPECT)

Answer:

radioactive tracer is injected intravenously and a computer reconstructs a 3D image based on a composite of many views

Question 7: contrast studies

Answer:

materials (contrast media) are injected to obtain contrast with surrounding tissue when shown on the x-ray film

Question 8: roentgenology

Answer:

study of x-rays; radiology

Question 9: radiopaque

Answer:

obstructing the passage of x-rays. structures appear white on the x-ray film

Question 10: positron emission tomography (PET)

Answer:

positron-emitting radioactive substances given intravenously create a cross-sectional image of cellular metabolism based on local concentration of the radioactive substance; give information about organ function

Question 11: gamma rays

Answer:

high-energy rays emitted by radioactive substances in tracer studies

Question 12: radiolucent

Answer:

permitting thhe passage of x-rays. structures appear black on x-ray film

Question 13: transducer

Answer:

handheld device that sends and receives ultrasound signals

Question 14: tracer studies

Answer:

radionuclides are used as tags, or labels, attached to chemicals and followed as they travel through the body

Question 15: radionuclide

Answer:

radioactive form of an element that gives off energy in the form of radiation; radioisotope

Question 16: fluorescence

Answer:

emission of glowing light results from exposure to and absorption of radiation from x-rays

Question 17: fluoroscopy

Answer:

x-ray technique that produces a fluorescent image on an image intensifier

Question 18: radioimmunoassay

Answer:

test combines radioactive chemicals and antibodies to detect minute quantities of substances in a patient's blood

Question 19: uptake

Answer:

rate of absorption of a radionuclide into an organ or tissue

Question 20: ionization

Answer:

transformation of electrically neutral substances into electrically charged particles

Question 21: ventilation-perfusion studies

Answer:

radiopharmaceutical is inhaled (ventilation) and injected intravenously (perfusion) followed by imaging its passage through the respiratory tract

Question 22: radiopharmaceutical

Answer:

radioactive drug (radionuclide plus chemical) that is administered safely for diagnostic and therapeutic purposes

Question 23: tagging

Answer:

attaching a radionuclide to a chemical and following its path in the body

Question 24: half-life

Answer:

time required for a radioactive substance to lose half its radioactivity by disintegration

Question 25: labeled compound

Answer:

radiopharmaceutical; used in nuclear medicine studies

Question 26: radiology

Answer:

medical specialty concerned with the study of x-rays and their use in the diagnosis of disease; includes other forms of energy, such as ultrasound and magnetic waves

Question 27: gamma camera

Answer:

machine to detect gamma rays emitted from radiopharmaceuticals during scanning for diagnostic purposes
