SUMMARY

The prevalence of congestive heart failure (CHF) in Canada is high, representing one of the health care system's most expensive diagnoses. Despite major advances in medicine, the mortality and morbidity from CHF remains great. Currently, magnetic resonance imaging (MRI) is used for non-invasive imaging of the cardiovascular system to enable the structure and anatomy of the organ to be visualized. However, current MRI methods have limitations when assessing and aiding in the management of CHF. A new imaging method has recently been developed that is showing great promise as a tool in the management of patients with CHF. Rapid imaging of biochemical reactions within myocytes using MRI has recently become possible through the use of the Dynamic Nuclear Polarization (DNP) and dissolution method. DNP-dissolution results in an intravenous contrast agent that is hyperpolarized, producing a magnetic signal that is enhanced by up to 100,000 fold. The particular agent is carbon-13 labelled pyruvate. In this study, we demonstrate the first 13C-metabolic images of the human heart, along with the required hardware and data acquisition methods.
