By analysing the relationship between the types of diseases

syndromes diagnosis in apoplexy and CT scanning

it is claimed that the types of hitting channel and hitting collateral are mostly of ischemic type with minor lesion and clear surroundings or only mild blur ring

and without definite or only mild occupying lesions

while for the types of hitting the hollow or solid viscera

the lesions are rather big

with edematous or blurring surrounding

definite occupying lesions. The difference between the 2 types are significant （P<0. 01） . No obvious relations can be ruled out between the results of CT scanning and types and locations of lesions

side and number of lesions and syndrome types.
