Stroke: RAPID MRI analysis may speed up selection for tPA therapy.

摘要

RAPID, an automated image-analysis program, can calculate stroke lesion volumes from diffusion-weighted and perfusion-weighted MRI (DWI and PWI) within 10 min and without requiring operator input. "These features make RAPID an attractive tool for patient selection in acute stroke trials," report Maarten Lansberg and colleagues in Stroke. Specifically, RAPID-generated images could be used to speed up and standardize the selection of patients for reperfusion therapy: "RAPID processing of a baseline MRI... has the potential to determine whether a patient is a good candidate to receive treatment aimed at restoring perfusion to the ischemic brain," they conclude.
