JCMR 2020; 22.54. Breath-hold and free-breathing quantitative assessment of biventricular volume and function using compressed SENSE: a clinical validation in children and young adults (CME)

Purpose/ Objective

Although the accuracy and reproducibility of CMR bSSFP for the measurement of ventricular volumes, function, and cardiac mass is well established, the requirement for repeated breath-holds remains a limitation, especially in children and sedated patients. Strategies to reduce breath-hold duration or elimination of breath-hold using novel techniques need to be clinically validated against clinical reference standard to study the potential side effects of such strategies. What is the ideal state/ if the problem is gone? Preferably reduction in breath-hold duration and ideally elimination of breath-holds to accommodate patients with impaired breath-holding capacity with comparable measurement of ventricular volumes, function, and cardiac mass along with diagnostic image quality for morphologic defects.

The comparison of the image quality and ventricular volumetric and functional indices using either breath-hold (BH) or free breathing (FB) cine bSSFP imaging using C-SENSE acceleration with BH SENSE cine bSSFP imaging will help practitioners determine judicious use of C-SENSE acceleration, to accommodate patients with impaired BH capacity.

To close the gap outlined above:

  1. While attempting to reduce or eliminate the breath-holds in cine acquisition for volumetric and functional assessment learners need to know about the tradeoffs of data under-sampling strategies with spatial and/or temporal fidelity, and differences in prospective versus retrospective gating.
  2. Learners need to know how to judiciously apply amount of acceleration depending on the underlying data under-sampling and reconstruction scheme to keep trade offs within clinically acceptable limits.
  3. Learners need to do perform assessment of differences in volumetric and functional indices along with image quality to determine optimal use of available acceleration for their target patient population.
