Our study suggests that ultrasound is reliable and may replace plain radiograph for the identification of the UVC position, preventing complications from malposition, and reducing exposure to ionizing radiation.
In cases of equivocal diagnostic CT, SPECT/CT bridges the gap between MIBG scintigraphy and diagnostic CT, with guidance of the diagnostic CT and characterization of its findings. In this small series, MIBG SPECT/CT increased the diagnostic certainty in 89% of discordant studies.
The presence of an inner fatty core in the intussusception, lesion diameter, wall thickness, the ratio of fatty core thickness to outer wall thickness, and the presence of lymph nodes in the lesion may enable reliable differentiation between ileocolic and small-bowel intussusceptions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
