Cerebral stalk is occurrence problem of the film inside the blood-vessel inside the head commonly, cause the symptom that is short of blood thereby. Generally speaking, unless be very inchoate head stalk, otherwise, can come through symptom and examination fish. Of course, very inchoate slight head stalk also can pass fish of nuclear magnetic resonance. General head stalk comes through Ct fish. The place that is short of blood commonly can appear slight haemorrhage symptom.
The size that cerebral CT checks dead focus of a disease of indication head stalk and place accuracy rate 66.5% ～ 89.2% , those who show earlier cerebral hemorrhage is accurateForum of baby of new Shanghai noble Lead 100% . Accordingly, inchoate CT examination conduces to differentiate diagnose, can eliminate a head to go out1000 beautiful net dragon of Shanghai1000 beautiful nets of Shanghai Phoenix forum Blood. Come on to death when cerebral stalk inside 24 hours, or infarction kitchen is less than 8 millimeter, or pathological changes is in in cerebral doing and cerebella, cerebral CT examination often cannot offer correct examine to break. Should be in when necessary short-term inside check, lest incur loss through delay is treated.
CT shows stalk dead kitchen is low density, the place of OK and specific pathological changes, appearance reachs size, bigger stalk dead mess can make ventricle press press, be out of shape reach shift of central line structure, but cerebral stalk has disease to death 4 ～ inside 6 hours, only partial case of illness sees the kitchen range of a bit low density with not distinct border, and major case is shown in the ability after 24 hours1000 beautiful nets of Shanghai make friend Show the low density kitchen range with more distinct border, and the stalk dead kitchen that is less than 5mm. Skull sunken stalk absolutelies refuse to to be CT easily to show after, the stalk of coriaceous surface often also is aware of by CT to death. The check that enhances scanning to be able to increase pathological change goes out lead and qualitative diagnostic rate. Expression of dead CT of haemorrhage sex stalk is big low density there is irregular spot inside the area piece shape high density spends an area, it is low density area with the differentia of cerebral haematoma broader reach haemorrhage kitchen to show medicinal powder in flake shape.
The check that MRI straightens dead to the head goes out very sensitive, the check that is short of courage and uprightness to damage to cerebral ministry gives excel CT, can check gives more inchoate head to be short of courage and uprightness to damage, can be short of blood sees inside 1 hour. After having disease 6 hours, big stalk dies to be able to be shown by MRI almost, expression adds authority low signal for T1, t2 adds authority loud signal.
