Training activity information
Details
Identify a range of MRI artefacts and their causes. Demonstrate modifications to the acquisition protocol, hardware and/or reconstruction which reduce or eliminate them
Type
Developmental training activity (DTA)
Evidence requirements
Evidence the activity has been undertaken by the trainee​.
Reflection on the activity at one or more time points after the event including learning from the activity and/or areas of the trainees practice for development.
An action plan to implement learning and/or to address skills or knowledge gaps identified.
Considerations
- Physics of MR image acquisition and reconstruction
- Impact on image quality of pulse sequences, acquisition parameters, subject motion, triggering/gating and k-space trajectory
- Artefacts such as: aliasing; motion; ghosting; blurring; distortion; chemical shift; out-of-phase; Gibbs ringing; susceptibility/off-resonance; drop-out; RF noise; herring-bone; over-ranging; Nyquist; water-fat swap
- Artefacts in combination
- MRI hardware components and impact on image quality
