Ten signs of enlarged cerebral hemorrhage hematoma in CT images (top)
Time of Update: 2022-10-31
Black hole sign is a strict criterion for judging the degree of unevenness of CT values, which improves the reliability and objectivity of the previous hematoma inhomogeneity judgment, and for medical institutions that cannot carry out early CTA examination, CT-based non-contrast scanning can also predict the early hematoma enlargement of patients with cerebral hemorrhage.
