摘要: In this study, we investigated 40 patients (18 male, 22 female; mean age = 64.5 ± 11.0; GCS 9 to 14) with acute supratentorial spontaneous intracerebral hemorrhage (SICH) at admission by using a 1-tesla magnetic resonance imaging (MRI) unit equipped for single-shot echo-planar spin-echo isotropic diffusion-weighted (DWI) sequences. All DWI studies were obtained within 48 hours after symptom onset. Regional apparent diffusion coefficient (rADC) values measured in 3 different regions of interest (ROIs) drawn freehand on the T2-weighted images b 0 s/mm2 every section which hematoma was visible: 1) perihematomal hyperintense area; 2) 1 cm normal appearing brain tissue surrounding perilesional rim; 3) an area mirroring region including clot and placed contralateral hemisphere. rADC higher than areas (p < 0.001), increased levels all examined.
