Diagnostic Ultrasound with correct
answers 100% 2026
acoustic impedance - Correct Answers resistance of sound as it propogates through a medium
acoustic window - Correct Answers ability of sonography to visualize a particular area. (i.e. the
full urinary bladder is a good acoustic window to image the uterus and ovaries in a
transabdonimal sonogram)
anechoic - Correct Answers property of being free of echoes or without echoes
angle of incidence - Correct Answers angle at which the ultrasound beam strikes an interface
with respect to normal (perpendicular) incidence
ankle/brachial index (ABI) - Correct Answers ratio of ankle pressure to brachial pressure to
provide a general guide to help determine the degree of disability of the lower extremity
Doppler effect - Correct Answers shift in frequency or wavelength, depending on the conditions
of observation; caused by relative motions among sources. receivers, and medium
Doppler ultrasound - Correct Answers application of Doppler effect to ultrasound to detect
movement of a reflecting boundary relative to the source, resulting in a change of the
wavelength of the reflected wave
coronal image plane - Correct Answers anatomic term used to describe a place perpendicular to
the sagittal and transverse planes of the body
Detail resolution - Correct Answers includes axial and lateral resolution
, attenuation - Correct Answers weakening of the sound wave as it propogates through a medium
duplex imaging - Correct Answers combination of gray-scale real-time imaging and color or
spectral Doppler
complex - Correct Answers containing anechoic and echogenic areas
axial resolution - Correct Answers ability to distinguish two structures along a path parallel to
the sound beam
biparietal diameter (BPD) - Correct Answers largest dimension of the fetal head perpendicular
to the midsaggital plane; measured by ultrasonic visualization and used to measure fetal
development
continuous wave ultrasound - Correct Answers wave in which cycles repeat indefinitely; consists
of a separate transmit and receiver transducer housed within one assembly
color-flow Doppler - Correct Answers velocity in each direction is quantified by allocating a pixel
to each area; each velocity frequency change is allocated a color
echo - Correct Answers reflection of acoustic energy received from scattering elements or a
specular reflector
echogenic - Correct Answers refers to a medium that contains echo-producing structures
embryo - Correct Answers term used for a developing zygote through the
10th week of gestation
