ARRT Registry Exam review questions and
answers 2024\2025
What is the correct term used to describe an intravenous injection of a concentrated volume of contrast
media?
a. bolus
b. infusion
c. extravasation
d. luminal
- correct answer a. bolus
Which of the following methods utilizes a detector that captures x-ray energy and converts it into an
electronic signal?
a. indirect capture
b. CCD
c. cassette based radiography
d. direct capture
- correct answer d. direct capture
The energy of a characteristic x-ray photon created when an L shell electron fills a K shell vacancy in a
tungsten atom will have which of the following energies?
a. 69.5 keV
b. 57.5 keV
c. 91.5 keV
,d. 12 keV
- correct answer b. 57.5 keV
The energy of characteristic photons is determined by the difference in binding energies between the
two electron shells involved in the process, which in this question are K and L shells. 69.5 (K shell) minus
12 (L shell) equals 57.5.

Exposure latitude is also known as which of the following?
a. dynamic range
b. spatial resolution
c. subject contrast
d. characteristic response
- correct answer a. dynamic range
