fatty tissue
dense tissue
ducts
lymph nodes
A

ducts

2
Q

In xeroradiography, the mammographic image was displayed on:

cellulite film
a glass plate
a CRT monitor
plastic-coated paper

A

plastic-coated paper

3
Q

The acceptance of digital mammography lagged behind general digital radiography because of real or perceived problems with:

  1. image quality
  2. technologist education
  3. acquisition costs

1 & 2
1 & 3
2 & 3
1, 2, & 3

A

1 & 3

4
Q

The greatest challenge in the design of digital mammographic equipment was to create an image receptor large enough to cover the entire breast tissue while providing:

a low patient dose
reduced patient motion
a high level of detail
adequate breast compression

A

a high level of detail

5
Q

The disadvantage of divergent x-rays in mammographic imaging is:

an increase in patient dose
the possibility of missing tissue
a greater probability of patient motion
the need for compression

A

the possibility of missing tissue

6
Q

To help maintain spatial resolution during magnification, what change is made to the mammographic imaging technique?

a lower kVp is used.
a smaller image receptor is used.
a longer SID is used.
a smaller FSS is used

A

a lower kVp is used

7
Q

The benefits of using compression in mammography include all of the following except ___________.

elimination of patient motion
reduced patient dose
better spatial resolution
uniform exposure across the image

A

elimination of patient motion
