Abstract

CT of 117 cases of ischemic cerebral diseases clinically evaluated, were studied, and following results were obtained.

1) CT images of cerebral infarction may be classified to 4 types from the density level. Grade 0 (same as brain tissue), Grade 1 (slightly lower than brain), Grade 2 (evidently lower than brain) and Grade 3 (same as cerebrospinal fluid). The grades progress as time passes, and 50 to 60% of cases are grade 0 before 2 days after onset.

2) The margin of the low density area becomes clearer, as times pass, and the lesions with distinct margins increase in number 4 weeks after onset.
