© 2015 The Authors. Hyperpolarized 83Kr surface quadrupolar relaxation (SQUARE) generates MRI contrast that was previously shown to correlate with surface-to-volume ratios in porous model surface systems. The underlying physics of SQUARE contrast is... Read More about Hyperpolarized 83Kr magnetic resonance imaging of alveolar degradation in a rat model of emphysema.
