  		Figure 1. Lacunar lesions of the caudate nucleus. (a) Axial fluid attenuated inversion recovery image (IR-TSE 5000/100/1900) demonstrates no abnormalities. (b) The corresponding T2 weighted image (TSE 2229/110) clearly depicts a hyperintense lesion in the left head of the caudate nucleus.

  		Figure 2. Disturbed blood–brain barrier. (a) Axial fluid attenuated inversion recovery image (IR-TSE 5000/100/1900) demonstrates no abnormalities. (b) Corresponding post-contrast T1 weighted image (TSE 480/15) shows bilateral enhancement in the region of the basal ganglia.

  		Figure 3. Hyperintense brainstem lesion. (a) Axial fluid attenuated inversion recovery image (IR-TSE 5000/100/1900) shows only faint hyperintensity in the left pons. (b) The corresponding T2 weighted image (TSE 2229/110) reveals a better lesion/parenchyma contrast.
