Fig. 1From: Optic nerve sheath diameter change in prediction of malignant cerebral edema in ischemic stroke: an observational studyA flow chart of the included patients. Changes in CT parameters between CTpostprocedure and CTbaseline was used to predict early malignant progression (N = 12). In the remaining 46 patients, changes between CTD1 and CTbaseline was used to predict late malignant progression.
