The purpose of this submission is to educate technologists in performing magnetic resonance (MR) lymphangiography in conjunction with intranodal gadolium contrast injection in the pediatric patient. MR lymphangiography is a new procedure in the pediatric population. The lymphatic system plays the important role of transporting fluid from tissue back into the venous system via lymphovenous connections. Despite this key role, there has been a poor understanding of lymphatic flow physiology. The recent development of dynamic contrast intranodal MR lymphangiography, which provides quick and reliable access to the central lymphatic system, has provided insight into understanding the pathophysiology of several lymphatic flow disorders and provides guidance for interventional procedures. It also makes it possible to see central lymphatic anatomy with high spatial and temporal resolution. This allows clinicians to map the anatomy of the lymphatic system to determine the location of lymphatic leaks. MR lymphangiography may reduce the need for conventional IR lymphangiogram and spare patient’s radiation exposure. Read More

To provide MRI staff education on MRI fetal exams for sacrococcygeal teratomas. Sacrococcygeal teratoma (SCT) is a congenital germ cell tumor located at the base of the tailbone in newborns. This birth defect is generally not malignant. A SCT is most often diagnosed prenatally using routine obstetric ultrasonography, and further anatomical evaluation may require MRI. A SCT can grow during pregnancy and develop large blood vessels requiring more work for the fetal heart. SCT are more common in females than in males and occur in about 1 in 35,000 live births.
