WSC 2022 | Comparing CT and MRI for atrophy assessment in acute ischemic stroke

Tanaporn Jaroenngarmsamer, MD, Ramathibodi Hospital, Mahidol University, Bangkok, Thailand, shares the findings of a study comparing the use of CT and MRI in measuring cortical and subcortical brain atrophy in acute ischemic stroke. While MRI is the preferred imaging tool for these measurements, CT is most widely used in the acute stroke setting. Over 500 patients from the ESCAPE-NA1 trial with MRI and CT imaging data were included in the study. The hemi-intercaudate distance (h-ICD) was measured as a reflection of subcortical atrophy, while visual rating scales were used to assess cortical atrophy. The h-ICD and the cortical atrophy rating scales on CT were shown to correlate well with MRI in acute stroke patients. Dr Jaroenngarmsamer notes that physicians must be aware of the potential underestimation of atrophy severity when using CT in this context. This interview took place at the World Stroke Congress 2022 in Singapore.
