Radiology Modalities

Question 1

MRI

Answer 1

Magnetic Resonance Imaging is a diagnostic
procedure that uses a combination of a large magnet, radiofrequencies, and a
computer to produce detailed images of organs and structures within the body. Cross
sectional views can be obtained to reveal details. MRI does not use radiation, as do x
rays or CT scans. Education: Need to be a certified technologist.

Question 2

a diagnostic
procedure that uses a combination of a large magnet, radiofrequencies, and a
computer to produce detailed images of organs and structures within the body.

Answer 2

Magnetic Resonance Imaging

Question 3

“Slices”

Answer 3

Magnetic Resonance Imaging (MRI)
Computerized Tomography (CT)

Question 4

rays or CT scans.

Answer 4

Magnetic Resonance Imaging (MRI)

Question 5

What does CT stand for?

Answer 5

Computerized Tomography

Question 6

a diagnostic imaging
procedure that uses a combination of x-rays and computer technology to produce
cross-sectional images (often called “slices”), both horizontally and vertically, of the
body.

Answer 6

Computerized Tomography (CT)

Question 7

A _________ scan demonstrates detailed images of any part of the body, including the
bones, muscles, fat, and organs.

Answer 7

Computerized Tomography (CT)

Question 8

_________ scans are more detailed than general x-rays.

Answer 8

Computerized Tomography (CT)

Question 10

Used to detect and diagnose breast disease in women (and men) who either have breast problems such as a lump, pain, or nipple discharge, as well as for women (or men) who have no breast complaints.

Answer 10

mammogram

Question 11

use invisible electromagnetic energy beams to
produce images of internal tissues, bones and organs on film.

Answer 11

diagnostic x-rays

Question 12

a specialized area of radiology that uses very
small amounts of radioactive materials, or radiopharmaceuticals, to examine organ
function and structure.

Answer 12

Nuclear Medicine

a combination of many different
disciplines, including chemistry, physics, mathematics, computer technology, and
medicine. This branch of radiology is often used to help diagnose and treat
abnormalities very early in the progression of a disease, such as thyroid cancer.

Answer 13

Nuclear medicine

Question 14

uses high-frequency sound
waves and a computer to create images of blood vessels, tissues, and organs.

Answer 14

Ultrasonography

Question 15

also called sonography

Answer 15

Ultrasonography

Question 16

Used to view internal organs and to assess blood flow through
various vessels.

Answer 16

Ultrasonography

Question 17

Often used to examine many parts of the body such as the abdomen, breasts, female pelvis, prostate, scrotum, thyroid and
parathyroid, and the vascular system.

Answer 17

Ultrasounds

Question 18

During pregnancy, these are performed
to evaluate the development of the fetus.

Answer 18

Ultrasounds

Question 19

the treatment of
cancer and other diseases with radiation.

Answer 19

Radiation Therapy

Question 20

High energy x-rays are used to kill the
cancer cells by preventing them from multiplying.

Answer 20

radiation therapy

Question 21

used to cure or control cancer, or to alleviate some of the symptoms associated with cancer.

Answer 21

radiation therapy

Question 22

x-ray images of blood vessels in the body

Answer 22

angiograms

Question 23

the x-ray images allow a doctor to determine whether a blood vessel is
blocked, constricted, malformed, or otherwise obstructed or damaged.

Answer 23

angiograms

Question 24

What does the abbreviation PET mean?

Answer 24

Positron Emission Tomography

Question 25

a nuclear medicine functional imaging technique that is used to observe metabolic processes in the body as an aid to the diagnosis of disease.

Answer 25

PET Positron Emission Tomography

Question 26

This exam is a combination of nuclear medicine and CT imaging.

Answer 26

Positron Emission Tomography

Question 27

The system detects radioactive isotopes, which is introduced into the body. In modern scanners, three-dimensional imaging is often accomplished
with the aid of a computed tomography X-ray scan performed on the patient during the
same session, in the same machine.

Answer 27

Positron Emission Tomography
