Influence of Availabiity of Clinical History on Detection of Early Stroke Using Unenhanced CT and Diffusion-Weighted MR Imaging
AJR 179:223-228, Mullins,M.E.,et al, 2002
See this aricle in Pubmed

Article Abstract
Availability of clinical history indicating that early stroke is suspected significantly improves the sensitivity for detecting strokes on unenhanced CT without reducing specificity. In contradistinction, the availability of such a history d id not significantly improve the sensitivity for detecting stroke using diffusion-weighted MR imaging. Whenever possible, relevant clinical history should be made available to physicians interpreting emergency CT scans of the head.
