Comparative Study Clinical Trial Controlled Clinical Trial
Neuroblastoma: positron emission tomography with 2-[fluorine-18]-fluoro-2-deoxy-D-glucose compared with metaiodobenzylguanidine scintigraphy.
To assess the uptake in neuroblastoma of 2-[fluorine-18] -fluoro-2-deoxy-D-glucose (FDG) versus metaiodobenzylguanidine (MIBG). ⋯ Most neuroblastomas accumulate FDG. The mechanism of MIBG uptake is more intense prior to therapy. Concentration of FDG is not dependent on type 1 catecholamine uptake. FDG PET helps define the distribution of neuroblastomas that fail to concentrate MIBG.

Comparative Study
Congenital heart disease in adults and adolescents: comparative value of transthoracic and transesophageal echocardiography and MR imaging.
To compare the diagnostic value of transesophageal echocardiography and magnetic resonance (MR) imaging with that of transthoracic echocardiography in the evaluation of congenital heart disease in adults and adolescents. ⋯ Transesophageal echocardiography and MR imaging are beneficial complementary imaging techniques in adults or adolescents with congenital heart disease.
