Abstract
A variety of imaging modalities exist for the diagnosis of stroke. Several studies have been carried out to ascertain their contribution to
the management of acute stroke and to compare the benefits and limitations of each modality. Diffusion‑weighted imaging (DWI) has
been described as the optimal imaging technique for diagnosing acute ischemic stroke, yet limited evidence is available on the value
of DWI in the management of ischemic stroke with low‑field magnetic resonance (MR) systems. Although high‑field MR imaging (MRI)
is desirable for DWI, low‑field scanners provide an acceptable clinical compromise which is of importance to developing countries
posed with the challenge of limited availability of high‑field units. The purpose of this paper was to systematically review the literature
on the usefulness of DWI in acute stroke management with low‑field MRI scanners and present the experience in Nigeria.
