16层螺旋CT下肢血管CTA的QA与QC

目的:探讨16层螺旋CT下肢血管CTA的质量保证与质量控制。方法:22例下肢血管可疑病变患者患者行MSCTA检查,并行MIP、VR、MPR和CTVE重建。结果:22例下肢动脉病变的MSCTA均能获得准确的诊断,与DSA和手术结果比较,其敏感性、特异性和准确性均为100%。结论:加强16层螺旋CT下肢血管CTA的质量保证与质量控制具有重要的临床价值.

QA and QC of 16 Slices Helical CT Angiography in Lower Limb

Objective To investigate the quality assurance(QA) and quality control(QC)of 16 slices helical CT angiography in the lower limb. Methods 42 cases clinically suspected as the arterial disease of lower limb undergoing MSCTA were analyzed retrospectively. All reconstructed images were reformed by means of MIP, VR, MPR and CTVE. Results 22 patients were diagnosed correctly by using MSCTA. Compared to DSA and/or surgical results. Sensitivity, specificity and accurate rate were all 100%. Conclusion It is important to strengthen the QA and QC of the 16 slices helical CT angiography in the lower limb.
