Pediatric nuclear cardiology.

Echocardiography, magnetic resonance imaging and, more recently, multidetector computed tomography, have led to major advances in noninvasive image assessment of anatomy in pediatric cardiology. The radionuclide methods often lack sufficient resolution to precisely characterize complex morphology in congenital heart lesions. However, these methods provide an accurate and reproduceable quantitative assessment of the physiological consequences of structural heart disease. These unique capabilities will continue to assure ongoing clinical relevance of radionuclide methodology, as is the case in the assessment of heart disease in adult cardiology.
