Ch 8 intro to abd scanning

Question 1

Without internal echoes; the structure is fluid filled and transmits sound easily

Answer 1

anechoic or sonolucent

Question 2

Echo-producing structure; reflects sound with a brighter intensity

Answer 2

echogenic or hyperechoic

Question 3

Sound that travels through an anechoic (fluid-filled) substance and is not attenuated. There is increased brightness directly beyond the posterior border of the anechoic structure as compared with the surrounding area

Answer 3

enhancement, increased through transmission

Question 4

Interface between two fluids with different acoustic characteristics. This level will change with patient position

Answer 4

Fluid filled level

Question 5

Not uniform in texture or composition

Answer 5

Heterogeneous

Question 6

Completely uniform in texture or composition

Answer 6

Homogeneous

Question 7

Low levels with in the structure

Answer 7

Hypoechoic

Question 8

Usually refers to a diffuse disease process or metastatic disease

Answer 8

infiltrating

Question 9

Borders are not well defined, are ill-defined, or are not present

Answer 9

irregular borders

Question 10

Very close to normal parenchymal echogenicity patterns

Answer 10

isoechoic

Question 11

Well defined borders with internal echoes; the septa my be thin (likely benign) or thick (likely malignant)

Answer 11

loculated mass

Question 12

Sound beam is attenuated by a solid or calcified object

Answer 12

shadowing

Question 13

What three terms are used to describe various textures of the border of a structure?

Answer 13

smooth, well defined, and irregular

Question 14

What two terms may be used to identify the texture of a structure?

Answer 14

Homogeneous and Heterogeneous

Question 15

List the three terms that describe the transmission of sound?

Answer 15

increased, decreased and unchanged

Question 16

List the five sonographic and medical terms that describe the characteristics of an organ or mass?

Answer 16

anechoic, hypoechoic, isoechoic, hyperechoic, and echogenic

Question 17

Describe a cystic mass?

Answer 17

Smooth, well defined borders, anechoic, increased through transmission

Question 18

Described a solid mass

Answer 18

irregular borders, internal echoes decreased through transmission

Question 19

Describe a complex mass

Answer 19

Characteristic of both cystic and solid

Question 20

smooth border, anechoic, increased transmission

Answer 20

simple cyst

Question 21

few to low level internal echoes smooth border, no increased transmission

Answer 21

Hypoechoic

Question 22

mixed patterns of cystic and solid, fluid, debris, and blood; transmission may or may not increased.

Answer 22

complicated cyst

Question 23

well-defined with thin septa, increased transmission. Lobulated borders

Answer 23

lobulated cys

Question 24

Well defined with thick septa

Answer 24

Loculated cyst

Question 25

may have irregular borders and debris within; transmission may or may not be increased

Answer 25

abscess

Question 26

Has a uniform texture within

Answer 26

Homogenous mass

Question 27

Has a nonuniform texture within

Answer 27

Heterogenous mass

Question 28

Has a distorted architecture, irregular borders, and decreased transmission

Answer 28

infiltrating mass
