cellular and tissue activity

Question 17

positron emission tomography is often used to examine:

Answer 17

brain, heart, vessels

Question 18

Question 22

radiograph

Answer 22

record of x-rays

Question 23

radiography

Answer 23

process of recording x-rays

Question 24

radiologist

Answer 24

physician who specializes in x-rays (specifically the diagnosis and treatment of disease using medical imaging such as x-rays, computed tomography, magnetic resonance imaging, nuclear medicine, and sonography)

Question 25

radiology

Answer 25

study of x-rays (a branch of medicine concerned with the study and application of imaging technology to diagnose and treat disease)

Question 26

sonogram

Answer 26

record of sound

Question 27

sonography

Answer 27

process of recording sound (also called ultrasonography)

Question 28

tomography

Answer 28

process of recording slices (anatomical cross sections)

Question 29

computed tomography (CT)

Answer 29

imaging modality that combines x-rays with computer technology to produce detailed, cross sectional images of the body, called “slices.” Oral or intravenous contrast agent may be given to highlight specific regions in the body, resulting in clearer images.

Question 30

fluoroscopy

Answer 30

imaging of moving body structures, like an x-ray movie. An x-ray beam is passed through the body part being studied, and then the image is transmitted to a monitor in real time so that movement can be seen in detail. Contrast agent is often used to help identify and assess the function of different structures.

Question 31

nuclear medicine (NM)

Answer 31

imaging of internal structures by using a Gamma camera to detect radiation from different parts of the body after a radioactive material (radioisotope) has been given to the patient. Computer software assembles data into images called scans.

Question 32

magnetic resonance imaging (MRI)

Answer 32

high strength, computer-controlled magnetic fields producing a series of sectional images (slices) that visualize abnormalities such as swelling, infections, tumors, and herniated disks.

Question 33

scan

Answer 33

image obtained from diagnostic imaging procedures using sensing devices and (most often) radioisotopes.
