Water-soluble hyperpolarized (HP) 13C compounds represent a new class of MRI contrast agents which may revolutionize metabolic and functional imaging. We present a novel technique for the detection of pulmonary emboli created in a porcine model using the HP MRI contrast agent 2-hydroxyethyl acrylate. Our results indicate that HP 13C MRI angiography is a viable method for detecting pulmonary emboli.
