64-Slice Spiral CT Angiography in the Head and Neck Vascular Lesions of Clinical Application

Objective: To investigate the 64-slice CTA in the head and neck in the diagnosis of blood vessels.Methods: Cases of head and neck vascular CTA200 using maximum intensity projection MIP,volume rendering VRT,MPR and MPR software Inspace subtraction three-dimensional reconstruction techniques,multi-angle observations,of which 92 cases have MR,DSA and surgical information using double-blind comparison of various video effects,summed up the advantages and disadvantages of 64-slice CTA.Results: The 64-slice CTA less medication,small doses of radiation,scanning and imaging speed,image clarity,three-dimensional sense,the direction of rotation can be observed.VRT and MIP is the most commonly used method,Inspace Subtraction software can display the picture of the head and neck blood vessels.Conclusion: The 64-slice CTA can be used as head and neck vascular lesions of conventional screening methods can be widely used.
