69 Myocardial fibrosis in esophageal cancer patients Figure 4. (A1) Mean extracellular volume per left ventricular (LV) myocardial segment control patients. (A2) Mean extracellular volume per LV segment neoadjuvant chemoradiotherapy patients. (B) Average mean dose per LV myocardial segment (neoadjuvant chemoradiotherapy group). Cardiovascular Magnetic Resonance: Function measurements Left ventricular ejection fraction was 57.9 ± 13.6% in the nCRT group versus 57.4 ± 7.8% in the control group. End systolic volume index was 35.2 ± 10.0 versus 36.5 ± 8.9 ml/m2 and end diastolic index was 62.1 ± 15.0 versus 64.4 ± 15.9 ml/m2 for nCRT and control patients respectively. These differences were not statistically significant. 5
