2. Which provincial body must an MRT register with to practise in Ontario? → CMRITO
3. Which contrast agent is most commonly used for MRI enhancement? → Gadolinium-based contrast agent (GBCA)
4. For a PA wrist radiograph, the central ray is directed to which carpal bone? → Midcarpal area (capitate)
5. Which combination of geometric factors will result in the highest degree of image unsharpness (penumbra)? → Large focal spot, short SID, long OID
6. What is the purpose of dose-area product (DAP) measurement? → Estimate total radiation energy delivered, accounting for dose and field size
7. What membership option is available to a retiring 25-year practitioner? → Retired membership maintaining professional connection without practice requirements
8. A patient develops bronchospasm during contrast-enhanced CT. What is the first-line treatment? → Nebulized salbutamol
9. How do the Standards address documentation? → Complete, accurate, timely documentation of all examination information is required
10. What ongoing requirement is expected of CMRT-certified professionals? → Participate in continuing education to maintain certification.
11. What interprofessional communication behaviours do the Standards expect? → Clear, respectful, timely communication with all healthcare team members
12. What is the purpose of CAMRT professional liability insurance? → Provide financial protection against negligence or malpractice claims
13. What resource does CAMRT provide to support professional development? → Access to webinars, courses, and journals.
14. What is the purpose of the DLP (Dose-Length Product) metric in CT? → Estimates total energy imparted to the patient over the entire scan length
15. A newly certified MRT feels overwhelmed transitioning from student to practitioner. What strategies help? → Seek a mentor, set realistic goals, join graduate support programs, build a network
16. What is the Mortise view of the ankle and how is it positioned? → Demonstrates ankle mortise joint uniformly open; internally rotate 15-20 degrees
