Gadolinium DTPA (Gd-DTPA) is a paramagnetic blood-brain barrier contrast agent for MRI
that has been used primarily in adults. During May through October 1987, 17 children …

Conventional anatomic brain MRI is often limited in evaluating pediatric brain tumors, the
most common solid tumors and a leading cause of death in children. Advanced brain MRI …

Primary brain tumors are the most common solid neoplasms in children and a leading cause
of mortality in this population. MRI plays a central role in the diagnosis, characterization …
