FIGURE 1. Anterior planar images of lung 123I-MIBG scintigraphy (left, early images; right, delayed images) in representative control subject (Top) and COPD patient (Bottom). M, rt L, and lt L represent counts in ROIs at mediastinum, right lung, and left lung; E and D indicate early images (at 30 min after intravenous injection of 123I-MIBG) and delayed images (at 270 min after intravenous injection of 123I-MIBG), respectively. Note that rt LE, rt LD, lt LE, and lt LD, as well as washout rate (WR) between early and delayed images, are lower in COPD patient than in control subject.
