The authors investigated the feasibility of using T2-weighted, half-Fourier
rapid acquisition with relaxation enhancement, or RARE, dynamic susceptibi
lity contrast magnetic resonance (MR) imaging to depict crossed cerebellar
diaschisis. in 10 patients after unilateral supratentorial stroke, crossed
cerebellar diaschisis was demonstrated in the relative regional cerebellar
blood volume maps obtained with MR imaging. Cerebellar blood volume values
for the nonaffected cerebellar hemisphere were significantly larger than th
ose for the affected side (P = .0003).
