Neuroimaging Markers for Early Neurologic Deterioration in Single Small Subcortical Infarction

摘要

Background and Purpose-Early neurological deterioration (END) occurs in >= 20% of single small subcortical infarctions (SSSIs; axial diameter <= 20 mm in the perforator territories) and deters functional recovery. Both microvasculopathies and atherosclerosis have been proposed to independently contribute to the occurrence of END in SSSI cases. We hypothesized that the occurrence of END in SSSIs differs according to the pathological process.
