Accelerated real-time cine and flow under in-magnet staged exercise.

ABSTRACT:

Background

Cardiovascular magnetic resonance (CMR) imaging is a well-established imaging tool for diagnosing and managing cardiac conditions. The integration of exercise stress with CMR (ExCMR) can enhance its diagnostic capacity. Despite recent advances in CMR technology, quantitative ExCMR during exercise remains technically challenging due to motion artifacts and limited spatial and temporal resolution.

Methods

This study investigated the feasibility of biventricular functional and hemodynamic assessment using real-time (RT) ExCMR during a staged exercise protocol in 24 healthy volunteers. We employed high acceleration rates and applied a coil-reweighting technique to minimize motion blurring and artifacts. We further applied a beat-selection technique that identified bea
