1. What is the primary purpose of an MRI quality assurance program?
A. To maximize scan time
B. To eliminate the need for equipment servicing
C. To maintain consistent imaging performance and identify problems before
they compromise clinical imaging
D. To replace clinical image review
Correct answer: C
An MRI QA program systematically monitors equipment and imaging performance
so that changes can be detected and corrected. The goal is consistent, safe, and
diagnostically useful imaging rather than simply maximizing technical parameters.
2. What is the primary distinction between quality assurance and quality
control?
A. QA applies only to MRI safety
B. QC applies only to physicians
C. QA concerns only patient positioning
D. QA encompasses the broader system for maintaining quality, while QC
consists of specific monitoring and testing activities
,Correct answer: D
Quality assurance is the broader framework that establishes processes for
maintaining quality. Quality control consists of specific measurements, tests,
monitoring, and corrective actions used to verify that performance remains within
established limits.
3. Who should have responsibility for oversight of an MRI equipment quality-
control program under ACR guidance?
A. The receptionist
B. The MRI patient
C. A qualified medical physicist/MR scientist
D. The equipment manufacturer alone
Correct answer: C
ACR guidance states that a qualified medical physicist/MR scientist should have
responsibility for overseeing the equipment QC program and monitoring
performance after installation and routinely thereafter.
4. What is the primary purpose of documenting MRI QC results?
A. To increase the number of examinations performed
B. To establish a record of system performance and identify trends or deviations
C. To eliminate annual evaluations
D. To replace equipment specifications
Correct answer: B
Documentation provides a historical record against which current measurements
can be compared. It helps identify gradual deterioration, sudden changes, and
whether corrective actions were effective.
5. What should be established for a QC measurement so that future results can
be meaningfully evaluated?
,A. A random acceptable value
B. A different test method each week
C. A baseline or expected performance level
D. A new scanner serial number
Correct answer: C
A baseline establishes the expected performance of the system under defined
conditions. Future measurements can then be compared with that baseline to
identify meaningful changes.
6. What is a control limit used for in an MRI QC program?
A. To determine the patient's diagnosis
B. To select the MRI field strength
C. To calculate contrast dose
D. To identify measurements that require investigation or corrective action
Correct answer: D
Control limits define acceptable ranges for monitored parameters. A result outside
the established limit signals that the system or process should be investigated.
7. A weekly phantom measurement shows a gradual decline in SNR over several
weeks while remaining just within the control limit. What is the most
appropriate QA response?
A. Ignore the trend until the scanner fails
B. Immediately replace the magnet
C. Delete the previous measurements
D. Investigate the trend and continue monitoring according to the QC program
Correct answer: D
A gradual trend can provide an early indication of system degradation even before
a formal action limit is exceeded. Trend monitoring is therefore an important
component of effective QA.
, 8. Why should QC procedures use consistent acquisition and measurement
methods?
A. To make every patient scan identical
B. To reduce the magnetic field strength
C. To make measurements reproducible and comparable over time
D. To prevent the use of phantoms
Correct answer: C
Changing acquisition or measurement conditions can introduce variability
unrelated to actual system performance. Consistent procedures make longitudinal
comparisons more meaningful.
9. Which document is particularly important for defining the procedures and
methods used in an ACR-based MRI QC program?
A. The patient's medical record
B. The hospital cafeteria policy
C. The applicable MRI Quality Control Manual
D. The MRI appointment schedule
Correct answer: C
ACR states that QC testing must follow the written procedures and methods
outlined in the applicable MRI Quality Control Manual.
10. What should occur when a monitored QC parameter falls outside its
established control limits?
A. The measurement should automatically be discarded
B. The scanner should always be permanently removed from service
C. The result should be investigated and appropriate corrective action taken
D. The QC program should be discontinued
Correct answer: C
