Following publication of article [1] we noted an error in the methods section of our abstract in which we state: “Global MD was significantly higher in the septum than the reference lateral wall (0.784 ± 0.188 vs 0.750 ± 0.154 × 10-3 mm2/s, p < 0.001).” The word “Global” was not correct, and the reference value was incorrect, this should state: “MD was significantly higher in the septum than the reference lateral wall (0.784 ±0.188 vs 0.714 ±0.155 × 10-3 mm2/s, p <0.001).” All other information is correct, we apologize for any inconvenience caused by this error.
