Risk calculation based on five variables. Regions of interest on heart and mediastinum are shown. a In a 65-year old female patient with NYHA class II and LVEF 25 %, HMR was 2.3, and the mortality risk could be calculated as 4.9 %/5 years. b A 67-year old male patient with NYHA class I and EF 45 % showed HMR of 1.1, and calculated mortality risk was 32 %/5 years. Each prediction curve is drawn as a function of HMR based on the multiple logistic models of 5 parameters. During the follow-up, the first patient was alive for 5 years, and the second patient died from pump failure in 2.6 years after MIBG study
