Dear Sirs,

In a patient presenting with acute stroke it is essential to make a quick decision on thrombolysis based on history, clinical findings and the information obtained on an urgent CT or MRI. Though CT is considered the imaging technique of choice to rule out intracerebral haemorrhage, MRI using a gradient T2*/SWI sequence has been found to be equally good [1]. If the presentation is beyond the first 3 h, there is a need to image the salvageable penumbra. MRI gives information about the penumbra by using the diffusion–perfusion imaging. The role of susceptibility weighted imaging (SWI) in patients with stroke has already been documented [2]. We report two interesting cases of acute stroke where the findings in SWI helped in early diagnosis and management.

A 43-year-old male presented with wake up stroke and was rushed to our hospital. The patient could not move the right sided limbs and had aphasia. Magnetic resonance imaging done at 7.30 a.m, soon after his arrival in the...
