Bland-Altman plots depicting the intra- and interobserver variability between Multidetector Row Computed Tomography, and Cardiovascular Magnetic Resonance. Caption: Bland-Altman plots demonstrating the intra-observer (left side), and inter-observer (right side) variability of right ventricular a). end diastolic volume, b). end systolic volume, c). stroke volume, and d). ejection fraction. On the X-axis the mean value of both measurements, and on the Y-axis the difference between measurements. The Δ represent measurements performed with MDCT, the represents the mean of the differences between MDCT measurements. The represent measurements performed with CMR, the represent the mean of the differences between CMR measurements.
