Abstract
Stroke is the most common cause of mortality and morbidity worldwide. The prognosis
of stroke depends upon the area affected and its early treatment. Time is of the essence in the care
of stroke patients as it is estimated that approximately 1.9 million neurons, 14 billion synapses, and
12 km myelinated nerve fibers are lost per minute. Therefore, early diagnosis and prompt treatment
are necessary. The primary goal of imaging in acute stroke is to diagnose the underlying cause, estimate
the area affected, predict response towards thrombolytic therapy and to exclude the conditions
mimicking stroke. With advancements in radiology, multiple imaging modalities are available
for diagnosis and predicting prognosis. None of them is considered alone to be perfect. In this
era of multimodality imaging, the decision of choosing appropriate techniques depends upon purpose
and availability. Non-Contrast Computed Tomography is time effective, and helps in excluding
other causes, Trans Cranial Doppler is time-effective and cost-effective with wide availability,
however, is operator dependent and less sensitive. It holds a great future in sonothrombolysis. Magnetic
Resonance Imaging is so far considered to be the most superior one in terms of early diagnosis,
planning for interventional treatment and predicting the response of treatment. However, it is
limited due to high cost and lack of availability. The current review gives a detailed account of all
imaging modalities available for imaging stroke and their associated pros and cons.
