In summary, counting pitted erythrocytes provides an excellent and quantitative method with which to evaluate splenic function. Like computed tomography, magnetic resonance imaging provides no functional information about splenic activity, unless a spleen-specific agent is used. In summary, the reliability of magnetic resonance imaging in delineating splenic location, number, and size has not been proven in the heterotaxy syndromes. A review of the published results, nonetheless, indicates difficulties in accurately detecting small amounts of splenic tissue in patients with atypical anatomy. Newer spleen-specific agents such as superparamagnetic iron oxide may increase the role of magnetic resonance imaging in the assessment of splenic anatomy and function. Morphological characteristics of the atria and their variations, including characteristics in the splenic syndromes. Analysis of visceral heterotaxy according to splenic status, appendage morphology, or both. Embolic complications included splenic infarct or abscess, coronary embolism with myocardial infarction, pulmonary embolism, and peripheral limb embolization, but cerebral embolization was not included. The reliability of computed tomography and magnetic resonance imaging in detecting splenic tissue in the heterotaxy syndromes is unproven and perhaps only fair at best. Conversely, if clinical suspicion is high for asplenia, one may simply initiate daily antibiotic prophylaxis and reevaluate the splenic function after the newborn period. Either of these tests should probably be performed in all patients, since they provide information on overall splenic function. Despite the close association of certain constellations of cardiac disease with splenic status, however, the association is not perfect. The spleen: diagnosis of splenic diseases using radiolabeled tracers. These studies suggested that splenic precursors move along the stomach, and that an inhibitory ' anchor ' effect is exerted by the posterior spleno-pancreatic mesenchyme. In such cases, it would be necessary to generate monoclonal antibodies via the fusion of splenic cells of the immunized animal with immortal myeloma cells. Because splenic immaturity may produce ambiguous results in newborns, a repeat test may need to be done beyond early infancy. Pitting studies can also quantify splenic function, although the need for such quantification in the heterotaxy syndromes is not clear. A wide variety of tests is available to assess splenic function and/or anatomy. Because the evaluation of splenic function may be ambiguous in the newborn, or very young infant, one may then have to corroborate functional assessment with anatomic imaging. Dual radiopharmaceutical imaging may better separate hepatic from splenic tissue, but is typically done only after an equivocal study using sulfur colloid, necessitating a second test. Nor, a feature more germane to this review, can the constellation of cardiac malformations reliably be used to predict the absence or presence of splenic tissue. Our experience is that, despite the preponderance of splenic affinity for heat-damaged red blood cells, there is often sufficient liver uptake to make image interpretation difficult. Splenic scintigraphy may be helpful as an adjunctive test, but relatively poor spatial resolution, interfering hepatic activity, and possible need for transport mitigate its usefulness in the young infant. Surely, as logical descriptions of congenitally malformed hearts become increasingly adopted worldwide, it should be accepted that the concept of "splenic syndromes" leaves something to be desired.
