The The the first part of the the cranio-cervical at the junction of District, roughly and the sectional anatomy of research the purpose of: to understand the the important structure of the the at the junction of District, of the the cranio-cervical and Its Adjacent, and in-depth study the the the cross - sectional anatomy of the the important the structure of of of the the at the junction of District, of the the cranio-cervical, for that the provided by the regional imaging research the the anatomic basis for. Information and method: In this study, adopt that the warp to the the a fixed the normal adult cadaveric heads were of the Formalin 12 cases of (Tianjin Medical University, Department of Anatomy, to provide the), Male 9 cases of and the, female 3 cases, Age of 47-73-year-old, a an average of Age of 67.8-year-old. Of which 3 cases of used for to carried out the the the cranio-cervical at the junction of District, the gross anatomy observation of, 3 cases of made of to 5.0mm thick of the 6 cases of of the frozen slice, made of the the of the thin-layer slice of of the 0.5mm thick. Observation of the the the the morphology of the the important the structure of of of the the at the junction of District, of the the cranio-cervical and its adjacent to the the relationship between. Results: the cranio-cervical at the junction of District, is located in within the occipital bone, mastoid, temporal bone rock the Ministry of, atlantoaxial vertebral vertebral body, etc. bone sexual structure by the Wai into a of the gap, some of the important support ligament (wing-shaped ligament, cruciate ligament, odontoid process Tsim Sha Tsui ligament, atlanto-pillow before the, the the structure of the after the membrane, laminating) and nerve, blood vessels, etc. walk through the the of which. The ligament structure of the the region from the the after the forward is order of: membrane in the after the atlanto - occipital, laminating, the cruciate ligament (including the the upper and lower longitudinal fasciculus, transverse ligament), the ligament of wing-shaped, odontoid process the the the former membrane of the the the tip ligament and the the atlanto - occipital, of which laminating, cruciate ligament on the longitudinal fasciculus, odontoid process the tip ligament in the the the occipital bone the base the bottom of the adhesions closely, not easy to separation. Vertebral artery with the the first 1,2 cervical nerve is closely related to. Conclusion: the gross anatomy and running able to to the slice of the rift is better to display the the the important structure and its adjacent to the of of the the ligament of the the at the junction of District, of the the cranio-cervical, nerves, blood vessels, and, etc., for the in-depth carried out the imaging study of of the the at the junction of District, of the the cranio-cervical provides the anatomical basis for. The second part of the the cranio-cervical at the junction of District,, CT and MRI and Imaging Anatomy, research the purpose of: to study the the CT and MRI manifestations of the the important the structure of of of the the normal the cranio-cervical at the junction of District,, optimize the the imaging of the the important the structure of of of the the region check the method, to provide for this of the clinical diagnosis of the region the valuable the and Imaging Anatomy of the basis of. Information and method: in the the October 2006-May 2007 period, as at the the in our hospital line head and neck unenhanced and enhanced CT examination in the, and random select the 51 cases of those with normal, the of which men and 31 cases of, and and 20 cases of women, Age 34-60 years, mean age 49.4 years old, row Spiral CT cross-sectional scan, as coronal plane, the reorganization of sagittal plane, and enhance scans use by the elbow, injection of a non ionic iodine And contrast agent 100ml (350mg I of / ml in), vein,, flow velocity 4.0ml / s. Select None head and neck trauma, the 51 cases of of the a discomfort of the health volunteers, were male and 30 cases of and, female the 21 cases of, age of 20-39-year-old, with a an average Age of 27.3-year-old to, the use of the MRI multi--pulse sequence line cross - sectional, the coronal plane, the sagittal plane scanning. Combined with roughly and sectional anatomy of the, analysis of the the CT and MRI manifestations of the of of of each cross-section important the structure of of the at the junction of District, of the the cranio-cervical. Compare of each of the MRI pulse sequence on the the the the main ligament of the the at the junction of District, of the the cranio-cervical (atlanto - occipital after the membrane - the dura mater composite body, coatingS - the dura mater composite body, transverse ligament, wing-shaped ligament, former atlanto - occipital the the,) of the display the effect of of of the membrane. Measure the the parameters of the Imaging anatomy of the of the the important the structure of of of the the region. Results: CT and MRI, that makes it able to the better display the the important structure of the the at the junction of District, of the the cranio-cervical and Its Adjacent. The membrane - the dura mater composite body in the after the atlanto - occipital, coatingS - the dura mater composite body, transverse ligament and the wing-shaped ligament able to in the the on the the CT and the MRI clearly show the, an display rate of 100% (51/51); the odontoid process tip ligament only can be in the the median sagittal plane identification, the 29.4% of the the the display rate was of on the the in the CT (15/51), the the display rate was in the the MRI on the of the 43.1% (22/51); 100% of the the display rate was of the atlanto - occipital the former film in the the MRI on the of the (51/51), but in the on CT difficult to recognize. The two physician were, respectively, analysis of the the situation of the the display of the of MRI of each pulse sequence in the the the the the main ligament of the the of the the at the junction of District, of the the cranio-cervical, the research results show that the the-weighted image of the proton density display the the the the effect of of the the the main ligament of the the of the the region the best. . Comparing CT and the the MRI measurement value, results display basal angle, atlanto - occipital articular angle, the differences in of the of pillow teeth spacing, the the position of of odontoid and the left and right side atlanto-odontoid clearance difference in the the on the the CT and the MRI was no statistically significance (P> 0.05). Conclusion: CT, and MRI can better to display the the important structure of the the at the junction of District, of the the cranio-cervical and Its Adjacent. The proton density-weighted In like to can clearly show the the the the main ligament of the the at the junction of District, of the the cranio-cervical, can be used as the the ideal MRI imaging sequence of the the ligament structure of the of the the region, the appropriate to the imaging dimension of there are conducive to the the display of the ligament. The the the important the structure of of of the the region imaging measurement will help to the the the diagnosis of of the diseases.
