| ［Abstract］ Objective To investigate the operating matching problems of multi-slice spiral computed tomography angiography (MSCTA) and using high-pressure mechanical injector in multi-slice spiral computed tomography(MSCT).Methods Seven hundred and twenty cases aged from 18 to 85 were studied.The average age was 60.2 years. In these cases, 465 cases were male and 255 cases were female. SOMATOM sensation 64-slice spiral CT, ulich high-pressure mechanical injector and 370 mgI/ml ultravist for injection were used.Results Good imaging quality can be achieved when high-pressure mechanical injector was employed reasonably during MSCTA.Conclusion Skillful mastering of operating high-pressure mechanical injector and matching MSCTA scanning time with injection speed and dose are very helpful to raise the accuracy of clinical diagnosis. |
