Reliability of the WR on planar MIBG images calculated using method 1 (left panels) and method 2 (right panels): a intraobserver agreement, b interobserver agreement, c experienced versus inexperienced observer agreement. The mean differences (95 % limits of agreement) in the intraobserver analysis were −0.096 (−1.52 to 1.71) for method 1 and −0.38 (−7.34 to 9.07) for method 2, in the interobserver analysis were −0.18 (−2.50 to 2.16) for method 1 and 0.87 (−10.10 to 10.14) for method 2, in the experienced versus inexperienced observer analysis were −0.36 (−2.39 to 3.11) for method 1 and 2.38 (−11.50 to 16.26) for method 2, respectively
