Excerpt
Assessment of exercise intolerance is important in patients with cardiovascular disease. Traditionally, this is achieved by measuring maximum VO2 during cardio-pulmonary exercise testing (CPEX). However, this cannot discriminate between cardiac output and tissue extraction problems. A better approach may be to assess VO2 and cardiac output simultaneously (which also allows calculation of tissue extraction). Thus, we developed MR augmented CPEX in which real- time PCMR is performed at the same time as respiratory gas analysis. The purpose of this study was to validate this novel technology. …
