Coronary MRA with synchronised respiratory and cardiac motion using an external respirator reduces scan times and improves navigator efficiency S. Plein, T.N. Bloomer, J.P. Ridgway, T. Jones, Z.

Respiratory synchronisation • Modified RTX respirator* (Medivent, London, UK) • External respirator – no preparation required • Plastic cuirass, airtight seal, drive unit • Respiratory phases actively controlled by pressure change inside the cuirass: pressure: chest compression: expiration pressure: chest expansion: inspiration • Highly reproducible chest + diaphragm positions • ECG triggered mode: 1 full respiratory cycle per cardiac cycle. * S. Plein et al. Synchronising cardiac and respiratory motion with an external cuirass respirator. Poster 1834, ISMRM 2001
