Abstract

PURPOSE: The aim of this study was to investigate the clinical-radiological determinants of diffusion-weighted image (DWI) abnormalities in patients with suspected acute ischemic stroke (AIS) seen at the emergency room (ER).
METHODS: During the study period, 882 consecutive patients were screened at Clínica Alemana de Santiago, Chile; 786 had AIS and 711 (90.4%) were included.
RESULTS: DWI demonstrated 87.3% sensitivity and 99.0% specificity, with a positive likelihood ratio of 79 and a negative likelihood ratio of 0.13 for the detection of AIS. In the univariate analysis, a positive DWI in AIS was associated with admission National Institute of Health Stroke Scale (NIHSS) score (OR 1.09, 95% CI 1.04-1.1%), time from symptom onset to DWI (OR 1.03, 95% CI 1.01-1.05), presence of a relevant intracranial artery occlusion (OR 3.18, 95% CI 1.75-5.76), posterior circulation ischemia (OR 0.44, 95% CI 0.28-0.7), brainstem location of the AIS (OR 0.16, 95% CI 0.093-0.27), infratentorial location of AIS (OR 0.44, 95% CI 0.28-0.70), and lacunar (OR 0.27, 95% CI 0.11-0.68) or undetermined stroke etiology (OR 0.12, 95% CI 0.3-0.31). In multivariate analysis, only admission NIHSS score (OR 1.07, 95% CI 1.01-1.13), time from symptom onset to DWI (OR 1.04, 95% CI 1.01-1.13), brainstem location (OR 0.13, 95% CI 0.051-0.37), and lacunar (OR: 0.4, 95% CI 0.21-0.78) or undetermined etiology (OR: 0.4, 95% CI 0.22-0.78) remained independently associated.
CONCLUSION: DWI detects AIS accurately; the positivity of these evaluations in the ER is associated only with NIHSS on admission, time to DWI, brainstem location, and AIS etiology.
