  		FIGURE 1. 13N-NH3 and 18F-FDG PET images before and after steroid therapy in patient 12. Cardiac 13N-NH3 PET revealed moderate defects in basal anteroseptal wall of LV, and 18F-FDG PET revealed increased 18F-FDG uptake in basal anteroseptal-lateral wall and midanteroseptal wall of LV and free wall of right ventricle. After 1 mo of steroid therapy (prednisolone, 30 mg/d), increased 18F-FDG uptake in basal anteroseptal-lateral wall and midanteroseptal wall of LV was markedly diminished both in size and in intensity and that in free wall of right ventricle disappeared completely, whereas 13N-NH3 defects exhibited no significant change. 18F-FDG uptake indices of midanterior wall before and after steroid therapy were 2.8 and 1.8, respectively. Base = basal level of LV; Mid = middle level of LV.

  		FIGURE 2. 13N-NH3 and 18F-FDG PET images before and after steroid therapy in patient 15. Cardiac 13N-NH3 PET revealed moderate defects in basal ventricular septum, and 18F-FDG PET revealed increased 18F-FDG uptake in basal and midanteroseptal wall of LV and free wall of right ventricle. After 1 mo of steroid therapy (prednisolone, 30 mg/d), increased 18F-FDG uptake in basal and midanteroseptal wall of LV and free wall of right ventricle disappeared completely, whereas 13N-NH3 defects exhibited no significant change. 18F-FDG uptake indices of midseptum before and after steroid therapy were 3.0 and 1.2, respectively. Base = basal level of LV; Mid = middle level of LV.
