Fig. 2A —71-year-old man with pulmonary emphysema. R=right. CT shows bullous changes in both peripheral lungs and organized consolidation in left lung (left image, arrows). Deep-inspiratory breath-hold (DIBrH) SPECT shows more heterogeneous defects compared with non-breath-hold SPECT, with expansion of several defects (center image, arrows). Image set of transaxial DIBrH SPECT, SPECT/CT fusion, and CT confirms perfusion defects associated with bullous changes or consolidation on CT (right image, arrows). Heterogeneous defects are also seen in normal right ventral lung on CT.
