Paradoxical regional myocardial uptake between 201Thallium and 123I-BMIPP SPECT in patients with cardiomyopathy.
The clinical significance of the paradoxical mismatched phenomenon between (201)Tl and (123)I-BMIPP is still unknown. We report two cases that revealed paradoxical regional myocardial uptake between two tracers in patients with cardiomyopathy. There may be abnormal myocardium in these patients where active transportation of (201)Tl is disturbed and passive transportation of (123)I-BMIPP is not disordered.
