Background We compared two simple and rapid diameter‐based methods (ABC/2, od‐value) in terms of their accuracy in predicting lesion volume >70 ml and >100 ml. Methods In 238 DWI images of ischemic stroke patients from the AXIS2 trial, maximum lesion diameter and corresponding maximum orthogonal diameter were measured. Estimation of infarct volume based on od‐value and ABC/2 calculation was compared to volumetric assessments. Results Accuracy of od‐value and ABC/2 was similar for >70 ml (92.0 vs. 87.4) and >100 ml (92.9 vs. 93.3). ABC/2 overestimated lesion volume by 29.9%, resulting in a lower specificity. Conclusions Od‐value is a robust tool for patient selection in trials.
