The findings support the use of noncontrast CT plus angiography (NCCT) to assess a patient for thrombectomy, the international researchers say.

In the CT for Late Endovascular Reperfusion (CLEAR) study, results for a cohort of 1600 patients from 15 hospitals in five countries across North America and Europe were
