The Sectional Imaging Anatomy Of The Cerebellumblood Supply Partition

Objective:Discussed in detail the anatomy of small cerebral tomography for the district, to lay the foundation for anatomical imaging to pinpoint the diagnosis of cerebellar lesions and vascular surgery treatment.Material and Methods:After the selection of the bodies of people adult skull 12(9 male, female 3), respectively, to obtain CT and MRI images, the use of electric faults band made legal by equidistant transverse layer thickness 8mm specimens six cases, sagittal CT specimen 2 cases and four cases of coronary CT specimens. Selection of 10 healthy volunteers(8 males and 2 females), using PHILIPS 1.5T whole body MRI scanner and workspace R2.6.3.1 image post-processing workstations, respectively, to obtain transverse, sagittal and coronal MRI images. And selection of Dong E People’s Hospital in February 2012-2014 February hospitalized cases of small cerebral MRI, CT images. The corpse fault specimens and the corresponding image with healthy volunteers CT, MRI image control study, combined with typical cases of cerebellar infarction, clarifying zoning and CT images of the anatomical characteristics of small cerebral blood supply.Results:Cerebellar tentorium face by a rock bone surface, under the pillow face, namely SCA, AICA, PICA blood supply to the area. Cerebellum is above the level of splitting up and down relationship, split level, square lobular tentorium under section single lobular central lobular and lobular first half of SCAt, since the order of the forward foreign m SCAt, i SCAt, l SCAt, three fan-shaped distribution respectively supply 1 /3 of the screen surface hemisphere, back inside to m SCA, anterolateral to l SCA, between the two of i SCA. From the outside edge of the front and rear lateral cerebellum edge formed by the intersection of the outer corner of the cerebellum is AICA and PICA ’s boundaries appear through the pons, medulla via transverse layer and the upper parts of the trigeminal nerve, the vestibular cochlear nerve transection level. Prior to the outer corner of pompons, cerebellar peduncle, rock bone surface portion of the second abdominal leaflets, formed part of a single leaflet was AICAt. Second part of the abdomen below the level of crack leaflets, leaflets formed under the pillow face the second half of the blood supply to the area for PICA, back inside to m PICAt; anterolateral to l PICAt.After the pons, the trigeminal nerve transection layer : between the trigeminal nerve and petrous bone visible on the pompon copies, its tip toward the front. Outside corner appear in this level. Prior to the outer corner bobbles, cerebellar peduncle region mainly AICAt. Horizontal crack just appeared, after his move from the inside before the outside inside were m SCAt, i SCAt, l SCAt. After the medulla oblongata copies, vestibular cochlear nerve transection layer pompon most appear pompons and some single- lobular region AICAt. After AICAt outside of l SCAt. Near the tonsils is m PICAt, the outside is l PICAt.After cerebellar peduncle sagittal plane is next to the median sagittal plane : horizontal crack is slightly tilted forward to the next thread-like structures after a horizontal crack above, under the curtain mainly m SCAt. Horizontal fissure near the surface of the first half of lobular and under the pillow as m PICAt. Middle cerebellar peduncle and lower front area of AICAt. After sagittal CT petrous bone, lateral triangle, horizontal crack is clearly visible, horizontal split over the next screen from front to back were l SCAt, i SCAt, m SCAt. Below the level from front to back split cerebellum were l PICA, m PICAt. This level of the upper edge of the front is visible pompon AICAt.Through the corpus callosum, lateral triangle coronal CT : tentorium, horizontal crack is clearly visible, the next screen, above the level of the cerebellum to SCA blood split range, from the inside out in order to m SCAt, i SCAt, l SCAt. Middle cerebellar peduncle is AICAt.After the horn of the lateral ventricle coronal CT : In the screen, the horizontal crack from the inside out over the cerebellum were m SCAt, i SCAt, l SCAt. The following cerebellum horizontal fissure is PICAt, inside the center line near the tonsils is m PICAt, relying on outside of l PICAt.Conclusion:(1) tentorium surface, rock bone surface, respectively, under the pillow face SCA, AICA, PICA blood supply range. Above the horizontal crack, SCA supply area for the next screen,since the order of the forward foreign m SCAt, i SCAt, l SCAt. AICA and PICA lateral angle boundaries. Bone surface rock outside corner before pompon, cerebellar peduncle is formed AICAt. Horizontal surface is cracked under the following PICA feeding area pillow, back inside to m PICAt; anterolateral to l PICAt.(2) through the pons, the trigeminal nerve transection layers: the outer corner bobbles before, cerebellar peduncle region AICAt. The level before the crack inside the forward outside from the inside were m SCAt, i SCAt, l SCAt. After the medulla oblongata copies, vestibular cochlear nerve transection layer pompon, single leaflets as part AICAt. After AICAt outside of l SCAt. Near the tonsils is m PICAt, the outside is l PICAt.( 3) The cerebellum sagittal plane of the foot near the median sagittal plane : horizontal crack is a slightly tilted from the thread-like structure under the forward horizontal crack above, under the curtain mainly m SCAt. Horizontal fissure near the surface of the first half of lobular and under the pillow as m PICAt. Cerebellar peduncle and lower front area of AICAt. After sagittal CT petrous bone, lateral triangle, horizontal crack is clearly visible, horizontal split over the next screen from front to back were l SCAt, i SCAt, m SCAt. Below the level from front to back split cerebellum were l PICA, m PICAt. This level of the upper edge of the front is visible pompon AICAt.( 4) via the corpus callosum, lateral triangle coronal CT : tentorium, horizontal crack is clearly visible under the screen, above the level of the cerebellum to SCA blood split range, from the inside out in order to m SCAt, i SCAt, l SCAt. Middle cerebellar peduncle is AICAt. After the horn of the lateral ventricle coronal CT : In the screen, the horizontal crack from the inside out over the cerebellum were m SCAt, i SCAt, l SCAt. The following cerebellum horizontal fissure is PICAt, inside the center line near the tonsils is m PICAt, relying on outside of l PICAt.
