6 month-old male infant with increasing head circumference and pathology proven DIG.

A) Findings: ROI measurement of the lowest areas of diffusion.

Technique: ADC map (1.5T, DWI b=1000, TR=7199, TE=97)

B) Findings: ROI measurements to obtain an rCBV ratio. Measurement of the area with the highest signal intensity corresponds with the highest CBV values divided by the normal contralateral white matter.

Technique: Grayscale rCBV map from DSC PWI (1.5T, TR=1630, TE=49, contrast=Multihance 0.1mmol/kg, first pass bolus)

C) Findings: Color rCBV map from DSC PWI shows areas of relative hyperperfusion (arrows) compared to the rest of the solid enhancing component within the tumor. These areas were excluded from measurement if they correspond with vessels on anatomic images.
