Results In 84 cases of nerve root type,stenosis was found in 438 intervertebral foramen,of which C6～7 and C5～6 intervertebral foramen stenosis accounted for 79.6%.The causes of intervertebral foramen stenosis were uncinate process articulation hyperosteogeny,intervenebral disc protrusion,vertebral body hypertrophy,zygapophysis hyperosteogeny and dislocation etc.40 cases of vertbral artery type manifested that vertbral artery became slim and deviousness as a result of the compression of vertbral artery （20.7%） by osteophyte.22 cases of myeloid type manifested with cervical spinal canal stenosis,hyperosteogeny of posterior vertebral body edge,posterior longitudinal ligament calcification and cervical intervertebral disc protrusion etc.

结果 84例神经根型中，发现椎间孔狭窄438处，其中C5～6和C6～7椎间孔狭窄占79.6%，椎间孔狭窄的成因有钩突关节骨质增生、椎间盘突出、椎体肥大、小关节突骨质增生、错位等；40例椎动脉型表现为骨赘压迫椎动脉（52.5%），导致椎动脉变细、粗细不均和椎动脉迂曲。22例脊髓型表现为颈椎椎管狭窄、椎体后缘骨质增生、后纵韧带钙化、椎间隙狭窄和颈椎间盘突出等。

It can accurately record the images of the soft tissue with different penetrability. Especially, it is able to catch small "sand-shaped" calcified focus which is of segment significance in the mammary gland duct. This technology, combined with directional piercing cytology inspection, can accurately determine the confinement of the breast lump, and detect all breast tubercles.
