Abstract

The aim of this study was to compare cardiac volume and function assessment using PET with the reference technique of cardiovascular magnetic resonance (CMR). Methods: Left ventricular (LV) and right ventricular (RV) end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), and ejection fractions (EF) were measured in 9 patients using both CMR and PET with inhaled C15O. Results: Correlation between the techniques was generally reasonable (r values ranged from 0.63 to 0.99). Best agreement was seen for ESV (LV and RV). With PET, there was a tendency to underestimate LV EF and EDV, and RV EDV and SV. Agreement was worst for LV SV. Percentage difference between CMR and PET measurements ranged from -2% to 15%; Bland-Altman limits of agreement ranged from 24% to 75%. Conclusion: Although small systematic differences exist, the agreement between PET and CMR suggests useful information regarding function, and volumes may be obtained from a standard PET protocol.
