Implication
Technical review demonstrates principles of segmented k-space cine MRI during breath-holding, highlighting reduced motion artifacts in cardiovascular evaluation.
Key Points
- To review the underlying physical principles, pulse sequence timing, and technical strategies of segmented k-space cine cardiovascular magnetic resonance imaging during breath-holding.
- Technical framework analysis of segmented k-space trajectory acquisition across successive cardiac cycles.
- Review of breath-holding synchronization paired with electrocardiographic gating to optimize temporal and spatial resolution.
- Segmented k-space acquisition divides data collection across multiple cardiac cycles, permitting complete cine loops within a single breath-hold.
- Breath-hold acquisition protocols substantially suppress respiratory ghosting and cardiac motion blur relative to conventional unsegmented imaging sequences.
