D. Ask a colleague to watch over it

6. A patient undergoing an MRI procedure is prescribed gadolinium-based contrast agents (GBCAs). Which property of GBCAs is essential for the MRT to consider to minimize potential risks to the patient?

B. Late Gadolinium Enhancement (LGE)

C. Echo Planar Imaging (EPI)

D. Gradient-echo sequence

8. An MRT is preparing a gadolinium-based contrast agent for a patient undergoing an MRI. What is the most critical consideration when preparing the pharmaceutical agent?

A. Ensuring the contrast agent is diluted to reduce side effects

B. Verifying the patient’s glomerular filtration rate (GFR) before administration

C. Using saline to reconstitute the agent if it has sediment

D. Administering the agent at room temperature to ensure patient comfort

9. For an MRI of the knee to assess ligament integrity, which parameter alteration would improve visualization of fine structures?

A. Decrease TE

B. Use a lower field strength

C. Decrease voxel size

D. Increase TR

10. When conducting an MRI of the heart, an MRT needs to choose the best sequence to assess myocardial function. Which sequence provides the most accurate assessment of cardiac motion and function?

A. Cine MRI

B. T2-weighted imaging

C. Diffusion-Weighted Imaging (DWI)

D. T1-weighted imaging

11. In cardiac MRI, how should an MRT adjust parameters to best visualize myocardial scarring?

A. Increase inversion time

B. Decrease TE

C. Increase TR

D. Use a lower field strength

12. For an MRI of the brain to evaluate for multiple sclerosis, which pulse sequence would be most appropriate?

A. T2-weighted

B. DWI

C. T1-weighted

D. FLAIR

13. In MRI, to reduce aliasing artifacts in a lower limb study, what should an MRT adjust?

A. Decrease the slice thickness

B. Use a higher gradient strength

C. Increase the field of view

D. Apply oversampling

14. When analyzing an MRI of the cervical spine in an elderly patient, which finding often represents a normal degenerative change rather than a pathological condition?

A. Cervical spondylosis

B. Vertebral fracture

C. Disc herniation

D. Spinal cord compression

15. During a quench, you are responsible for ensuring all personnel are accounted for. You notice a technician is missing. What is your immediate action?

A. Wait for the quench to end before searching

B. Assume the technician has already evacuated

C. Ask other staff members to search for the technician

D. Initiate a search to locate the missing technician

16. An MRT has completed an MRI scan for a patient who requires immediate follow-up care due to unexpected findings. Which is the most appropriate action to ensure the appropriate transfer of care?

A. Inform the patient directly about the findings and advise them to see a specialist

B. Discuss the findings with the patient and refer them to the emergency department for further care

C. Wait until the radiologist reviews the images before taking any action

D. Document the findings in the patient’s report and notify the referring physician immediately

17. An MRT is scheduled to perform an MRI scan on a patient for gender-affirming surgery planning. The MRT has personal beliefs that conflict with the procedure but understands their responsibility to provide unbiased care. What should the MRT do in this situation?

A. Politely inform the patient of their personal beliefs and refuse to perform the scan

B. Delay the scan until a decision is made about their participation in similar cases in the future

C. Ask a colleague to take over the case without notifying their supervisor
