Abstract:
Objective:To evaluate the diagnostic value of subtraction CT angiograph(SCTA)and volume CT Digital subtractionangiography(VCTDSA) in detecting intracranial aneurysms,and compare their performance.Methods:Previously publishedliteratures concerning the diagnostic performance of SCTA between 1990 and 2008 were retrospectively reviewed(seven in English andtwo in Chinese),and were analyzed and compared with the performance of VCTDSA in detecting and characterizing of intracranial aneurysms.Then the correlated information was extracted,and the diagnostic sensitivity and specificity of intracranial aneurysms by the two kinds of technique were analyzed.Results:Except the data of Imakita、Romijn which the sensitivity of detecting intracranial aneurysms were 92% and 99%,the sensitivity of others were 100%,and the specificity of detecting intracranial aneurysms were 90% to 100%.88.9% of images were excellent quality(8/9)in the display of cerebral vessels and diagnostic information of intracranial aneurysms.The image quality of VCTDSA was excellent compared with other subtraction CT angiography,and it could completely display the whole cerebral vessels,including 5 grade branches and the clear relationship among artery-veins,aneurysms and parent artery of aneurysms.Conclusion:Compared with Subtraction CT angiography,VCTDSA has an advantage in the diagnosis of intracranial aneurysms.
