Application of low doses of digital subtraction angiography three-dimensional reconstruction in joint fracture of the trauma / 国际外科学杂志

ObjectiveTo compare X-ray,spiral CT and low does digital subtr,action angiongraphy technology of three dimensional reconstruction in 30 cases of the applications in the joint fractures,to study the application value of the digital subtraction angiography three- dimensional reconstruction in joint fracture.MethodsA retrospective analysis was made on 30 cases with joint fracture in Guangdong Provincial Guangzhou Development District Hospital,who were confirmed by the X-ray and spiral CT three-dimensional reconstruction and digital subtraction angiography three-dimensional reconstruction and the demonstrations three-dimensional reconstruction,spiral CT three-dimensional reconstruction and X-ray were compared.ResultsAll 30 cases fractures showed clear line,line of walk line,of the number of fracture,source and separation shift condition.Digital subtraction angiography could be clearly shows 30 cases in spiral CT could clearly show in 20 cases,10 cases not clearly show in,while X-ray clearly show in 10 cases,not show in 20 cases.Spiral CT showed clearly joint capsule and soft tissue.The SPSS 11.0 statistical soft package was used.Spearman correlation analysis,the single factor analysis of variance and the independent t test and the chi-square test were employed for data analysis,P ＜ 0.05 was considered statistical significance.Conclusions Digital subtraction angiography three-dimensional reconstruction can more clearly display fracture line,fracture pieces,walk line,source and separation shift condition compared with spiral CT and Xray essaminations,which is helpful for treatment options and prognosis estimation.

Diagnostic value of multi-slice helical computed tomography in spinal tuberculosis / 中国基层医药

Objective To investigate the diognostic value of multi-sllce helical CT(MSCT) in spinal tuber-culosis, and making a further understanding of this disease. Methods The MSCT and post-processing films manifes-tations of 23 spinal tuberculosis proved by operation and pathology were reviewed retrospectively. Results MSCT could show the bone destructions location, range, relationships with neighbor tissues, osseous vertebral narrowing and para-vertebral abscess,etc. MPR, CPR, SSD and VR could more completely and stereoscopically show these character-istics of spinal tuberculosis. Conclusion MSCT post-processing techniques could make up for the lack of axial CT scan. It has high value in elevating the diagnosis accuracy of spinal tuberculosis.
