Ischaemic stroke

(A) Non-contrast T1-weighted MRI. (B) Post-contrast T1-weighted MRI showing minimal increase in leptomeningeal vessels over the right frontal region. (C) Diffusion-weighted image (DWI) showing a hyperintense area in the right frontal region. (D) Apparent diffusion coefficient (ADC) map shows hypointense lesion, indicating restricted diffusion that correlates with high intensity on DWI and exponential diffusion. (E) ADC value is 0.22 x 10³ mm²/second, corresponding to a hyperacute infarct
