ARMRIT MRI Certification Exam – Real Exam Questions
with Verified Answers – Comprehensive MRI Physics and
Safety Review Guide
Introduction
This document contains real ARMRIT MRI exam-style
questions with verified answers covering MRI physics, image
formation, pulse sequences, safety regulations, gradient
systems, contrast agents, spatial localization, and image
quality concepts. The material focuses on certification
preparation through question-and-answer review of
commonly tested MRI principles and clinical applications. It
includes detailed explanations for selected answers and
covers both technical and patient safety topics relevant to MRI
technologists. The content serves as a valuable review
resource for ARMRIT examination candidates.
Exam Questions and Answers
45.A technique to avoid "crosstalk" between slices with little
or no slice interval is--- correct precise answer ---
Interleaving (gaps)
46.An efficient digital implementation of the mathematical
method for con-verting a time-varying signal into its
frequency and/or phase components is--- correct precise
answer --- Fast Fourier Transform
47.The "best" technique for improving image quality is to
increase--- correct precise answer --- NEX
, 48.Spatial Resolution is an image quality factor determined by
& : Slice thickness / Pixel size
49.Residual, undesirable gradient magnetic fields that persist
for a variable time duration after the pulse of electricity from
the gradient power supply is terminated are known as---
correct precise answer --- Eddy currents
50.The number (#) of slices formula is--- correct precise
answer --- TR / (TE + )³
51.Which parameter in a pulse sequence helps prevent
"crosstalk" between two adjacent images?--- correct precise
answer --- Slice interval
52.For the following spin-echo protocol:
FOV: 320, TR: 500, TE: 25, Slice Thick: 5mm, Slice Gap: 1mm,
Slice #: 9, NEX: 4, Matrix: 192
Increasing the FOV will--- correct precise answer ---
Increasing SNR
53.An IR pulse sequence can be which of the following---
correct precise answer --- All
54.Inversion Time, in an IR pulse sequence, is the time
interval between the--- correct precise answer --- 180 & 90
degree pulses
The time between the 180° inverting pulse and the 90°-pulse
is called the inversion time (TI). The (TR) and echo time (TE)
are defined as they are for spin echo
55.Which is a normally enhancing structure after the
administrati
gadolinium?--- correct precise answer --- Choroid plexus
