Biphasic Thallium 201 Spect-Imaging for the Noninvasive Diagnosis of Myocardial Perfusion Abnormalities in a Child

The mucocutaneous lymph node syndrome (Kawasaki disease) is of increas-ing importance for the pediatric cardiologist, for coronary aneurysms with the potential of thrombosis and subsequent stenosis can develop in the course of the disease. The authors report a 2½-year-old female child in whom, fourteen months after the acute phase of Kawasaki disease, myocardial infarction oc-curred. Biphasic thallium 201 SPECT-imaging using dipyridamole depicted an-terior wall ischemia and inferolateral infarction. This case demonstrates that noninvasive vasodilation-redistribution thallium 201 SPECT-imaging has the potential to predict reversible myocardial perfusion defects and myocardial ne-crosis, even in small infants with Kawasaki disease
