WebbOBJECTIVE To determine whether cardiac iodine-123 metaiodobenzylguanidine (123I MIBG) imaging is useful in predicting the prognosis of patients with chronic heart failure. DESIGN Cardiac 123I MIBG imaging was done on entry to the study. The cardiac MIBG washout rate was calculated from anterior chest view images obtained 20 and 200 … WebbWashout rate was calculated for 5 individual time intervals. There were no statistical differences in 123 I-MIBG washout rates (15 min to 1 h; 15 min to 2 h; 15 min to 4 h; 1 to 2 h; or 2 to 4 h between pre-transplantation and 1, 3, and 6 months postoperatively) see Table 2 and Figure 4 for details.
