MRI Final Exam: Questions With Step-by-Step
Solutions
If a local rectal coil is used, then it should be inserted: Correct
Answer - prior to the start of the exam
For MRCP, long TR and TE times serve to Correct Answer -
nullify the signal from all tissues except those with long T2 times
Fine matrix sizes in conjunction with short scan times can be
acquired in the pelvis by using Correct Answer - 1.
local/phased array/multi-array coils
2. rectangular FOV
3. fast spin echo (FSE)
Which of the following measures will help to produce a high quality,
diagnostic exam and a pleasurable experience for the patient
Correct Answer - 1. proper immobilization techniques
2. educating the patient on what to expect prior to, during, and after
the MRI exam
3. providing the patient with a blanket or other items necessary for
patient comfort
4. using the bore light and fan to increase brightness and circulation
If a hemorrhagic lesion is suspected, what type of pulse sequence
may be required Correct Answer - gradient echo (GRE)
Thorough patient preparation should include which of the following
Correct Answer - 4. all of the above
1. Proper patient screening
2. complete patient medical history
3. adequate patient education
, If a radiologist ask for a T2 exam, he/she wants a Correct Answer
- coherent or balanced gradient echo
Regarding coil safety, the technologist should perform all of the
following EXCEPT Correct Answer - loop cables into coils to
reduce excess cables outside the bore of the magnet
For contrast enhanced MRA studies, mid-term acquisitions
demonstrate Correct Answer - capillary phase
Which of the following is NOT an obvious artifact when performing
MRI of the chest Correct Answer - peristalsis
To achieve fat suppression, technologist may use Correct Answer
- 1. STIR sequences
2. chemical/spectral presaturation techniques
The pulse sequence listed as especially useful for imaging the
pediatric brain is Correct Answer - axial/oblique IR T1
Most tumor protocols require technologist to scan Correct Answer
- before and after contrast media administration

blood volume in the capillary bed during systole is know as
Correct Answer - peripheral gating
Abbreviation ETL stands for Correct Answer - Echo Train
