Abstract
Objective:To evaluate the clinical value of O-MAR technique in postoperative CTA of intracranial aneurysms embolization.Methods:Twenty-five patients with postoperative CTA of intracranial aneurysm after embolization were collected.The raw data were reconstructed by FBP(group A) and FBP+O-MAR(group B) respectively.Mann-Whitney U test was used for comparisons of the effects of the metal artifacts reduction.t-test or Mann-Whitney U test was used for comparisons of objective evaluating indices (length of artifacts,CT value and image noise).Results:The subjective scores of group B were significant higher than group A (U=0.00,P＜0.01).There were significant differences between group B and group A in the length of artifacts ((15.4±3.2)mm and (38.8±7.1) mm,t=7.73,P＜0.01),CT value (t=2.99,P＜0.05) and inage noise ((35.1±12.5)HU and (137.5±58.3) HU,t=5.31,P＜0.01).Conclusion:O-MAR technique can reduce the metal artifacts effectively,correct CT values around the plants and improve the image quality.关键词
