A novel triggered real-time MRI approach improves slice registration during short breathholds, enabling accurate 4D ventricular function and flow assessment.
May facilitate efficient 4D cardiac MRI; leaves open prospective validation before clinical adoption.
Real-time interactive MRI is becoming the method of choice for many cardiac applications. One current limitation of real-time techniques is inaccurate slice registration during free-breathing. A simple "triggered real-time" imaging approach is proposed which enables the acquisition of synchronized and accurately registered real-time movie loops during short breathholds. Initial in vivo results demonstrate application to complete 4D ventricular function assessment and fully resolved flow imaging.
