MRI has assumed a central role in the detection of leptomeningeal metastasis for risk stratification of pediatric CNS tumors, but not all sequences are created equal for detection of tumor in CSF. In this presentation, we describe the strengths, weaknesses and tradeoffs of sequences commonly used for this purpose, and suggest guidelines for a targeted imaging protocol with increased sensitivity for leptomeningeal tumor, in less scan time.
