Case 13

Apparent diffusion coefficient (ADC mm²/s) indicates the degree of the diffusion of water molecules. The higher intensity of diffusion weighted imaging (DWI b1000 s/ mm²) shown Case 12 corresponds to the lower ADC. The same five cases with brain tumor are demonstrated as below.

Which brain tumor induces the lowest ADC of the five tumors ?

a.　Metastatic brain tumor

b.　Anaplastic glioma

c.　(Acoustic) Neurinoma

d.　Meningioma

e.　Malignant lymphoma
