DMS 100 Test 1 2026 – Introduction to Diagnostic Medical Sonography
Fundamentals Study Guide
What is echogenicity? - correct answer ✔✔ The strength or amplitude of the returning sound
echoes in an ultrasound
What does it mean to be hyperechoic? - correct answer ✔✔ appears white on the screen (ex:
bones and dense tissue)
What does it mean to be hypoechoic? - correct answer ✔✔ appears gray on the screen (ex:
lumpy nodes and tumors)
What does it mean to be anechoic? - correct answer ✔✔ appears black on the screen, usually
fluid filled (ex: cysts, vessels, water, etc)
A fluid filled structure is: - correct answer ✔✔ anechoic
What are the terms homogenous and heterogenous referring to? - correct answer ✔✔ texture
Homogenous - correct answer ✔✔ Consistent texture
Heterogenous - correct answer ✔✔ Irregular texture
The Doppler Effect - correct answer ✔✔ A change in sound frequency caused by motion of the
sound source, motion of the listener, or both
The Piezoelectric Effect - correct answer ✔✔ Describes the property of certain materials to
create a voltage when they are mechanically deformed or when pressure is applied to them
, The Piezoelectric Effect was first described by the _______ brothers in 1880 - correct answer
✔✔ The Curie Brothers
A-mode - correct answer ✔✔ Amplitude mode; the height of the sole on the image is related to
the strength (amplitude) of the echo generated by the reflector
B-mode - correct answer ✔✔ Brightness mode; method of displaying the intensity of an echo by
varying the brightness of a dot to correspond to echo strength
M-mode - correct answer ✔✔ Motion mode; appears as a group of horizontal wavy lines
What are 2 benefits of accreditation? - correct answer ✔✔ 1. You can take you aboard exams 60
days before graduation
2. You follow a specific, detailed curriculum that ensures a quality education
