To explore the correlations between parameters derived from conventional
diffusion-weighted imaging (DWI), intravoxel incoherent motion (IVIM), and
diffusion kurtosis imaging (DKI) with histopathologic features of pediatric
intracranial tumors.
A 15-year-old boy with medulloblastoma in cerebellum (WHO grade Ⅳ). The lesion shows hyperintense on T2-weighted image(a), hypointense on
T1-weighted image (b), and enhancement on post-contrast T1-weighted image (c).
The lesion (ROI) demonstrates hypointense on the ADC map (d), D map (e), and Dk
map (h), and hyperintense on the D* map (f), f map (g), and K map (i). The pathologic
diagnosis was medulloblastoma with high cellularity of
4928(cell/mm2)(j), high Ki-67 index of 80% (k), and MVD of 1.4% (l) (magnification,
× 200).
A 5-year-old boy with diffuse astrocytoma in brainstem
(WHO grade II). The lesion shows
hyperintense on T2-weighted image(a), hypointense on T1-weighted image (b), and
enhancement on post-contrast T1-weighted image (c). The lesion (ROI)
demonstrates hyperintense on the ADC map (d), D map (e), and Dk map (h), and
hypointense on the D* map (f), f map (g), and K map (i). The pathologic diagnosis was diffuse astrocytoma with
high cellularity of 1918(cell/mm2)
(j), high Ki-67 index of 1.1% (k), and MVD of 0.9% (l) (magnification, × 200).
