Magnetic resonance image intensity ratio, a normalized measure to enable interpatient comparability of left atrial fibrosis. Heart Rhythm. 2014;11(1):85–92. https://doi.org/10.1016/j.hrthm.2013.10.007 This study reported a method to quantifiy LA fibrosis, based in a normalized measure: image intensity ratio(IIR) defined as LA myocardial signal intensity divided by the mean LA blood pool signal intensity. IIR showed goodo correlation with intracardiac voltage.

Europace. 2017;19(8):1272–9. https://doi.org/10.1093/europace/euw219 This study aimed to obtain a comparable threshold between individuals of image intensity ratio (IIR) in order to detect LA fibrosis, based in a control group of young healthy volunteers. An IIR > 1.20 identified abnormal fibrotic tissue. IIR >1.32 was observed in dense scare of post-ablation patients.
