Figure 3 Comparison of the Delayed H/M Ratio in [123I]MIBG Scintigraphy Among the 3 Patient Groups
We determined the heart/mediastinum (H/M) count ratio from the delayed planer [123I]metaiodobenzylguanidine (MIBG) image. The delayed H/M ratio was significantly lower in group IIa and in group IIb compared with that in group I. Data for individual subjects and the corresponding mean ± SD values are shown.
