Examples of LGEpos patterns and quantification methods. a & b A mid-ventricular LGE image with inferior and superior RVIP LGE (a). Endocardial and epicardial contours are drawn using cvi42 (b) and the maximum area of hyper enhancement selected. Areas of LGE are quantified using full-width-half maximum methodology and appear pixelated. LGE is given as grams and represented as percentage of total left ventricular mass. This patient had membranous nephropathy, stage 2 CKD and was in remission at the time of CMR. c & d Mid-wall LGE; Horizontal long axis 4-chamber view (c) and corresponding mid short axis view (d) showing extensive septal and lateral mid wall LGE in a patient with CKD secondary to Adult Polycystic Kidney Disease. The patient initially underwent a CMR as part of a research study and was asymptomatic. Coronary angiogram was normal. Ambulatory ECG monitoring demonstrated sinus rhythm with no arrhythmias. He later had a successful renal transplant with no arrhythmias or deterioration in LV function. Follow up CMRs have confirmed fixed appearances of LGE. e & f Sub-endocardial; Vertical long axis 2-chamber (e) and corresponding short axis view (f) demonstrating focal inferior sub-endocardial infarction.* The patient had focal segmental glomerular sclerosis with stable CKD stage 3 disease. The patient was asymptomatic. He underwent a CT coronary angiogram and calcium score which demonstrated moderate coronary calcification above the 90th centile for age and gender but no evidence of coronary artery stenosis. g & h Sub-epicardial LGE; Horizontal long axis 4-chamber view (g) and corresponding basal short axis view (h) with sub-epicardial LGE in the basal-mid inferior wall. The patient was a 59 year old with Adult Polycystic Kidney Disease and stable CKD stage 3a. He was asymptomatic. There has been no clinical history suggestive of either sarcoidosis or myocarditis. * Images e & f were originally published in QJM: An International Journal of Medicine [15]
