Abstract：Objective To explore the application of dual‐phase 3D CE‐MRA in head and carotid artery stenosis .Methods The dual‐phase 3D CE‐MRA and digital subtraction angiography (DSA) were performed in 51 cases suspected with head and carotid artery stenosis .We made a correlated comparison concerning the diagnostic results of arterial‐phase 3D CE‐MRA ,dual‐phase 3D CE‐MRA and DSA .Results Compared with the results of DSA ,which was regarded as the “gold standard” ,the sensitivity ,specificity ,positive predictive values ,negative predictive values and the total corresponding rate of arterial‐phase and dual‐phase 3D CE‐MRA in head and carotid artery stenosis were 90 .81% and 90 .81% ,92 .96%and 95 .62% ,98 .09% and 98 .14% ,71 .79% and 80 .38% ,92 .6% and 94 .83% ,respectively .The consistent rates in di‐agnosis on mid‐stenosis ,moderate‐stenosis ,severe‐stenosis and complete occlusion were 81 .10% and 89 .86% ;60 .65%and 74 .07% ;91 .30% and 95 .45% ;78 .58% and 91 .67% .Conclusion Compared with the arterial‐phase 3D CE‐MRA , the dual‐phase 3D CE‐MRA is less time‐consuming .It results in fewer doses of the contrast media ,reducing patience’s cost ,but providing more accurate diagnosis .The dual‐phase 3D CE‐MRA has particular advantage and will be a safe ,non‐invasive ,reliable and new examination in diagnosis of head and carotid artery stenosis .
