Abstract:
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.
