【摘要】 目的 对比分析双源CT、3.0T MR和DSA在颅内动脉瘤诊断中的特点及其临床应用价值。方法 回顾性分析102例颅内动脉瘤患者的双源CT、3.0T MR和DSA影像学表现。结果 102例患者均行DSA检查,60例行双源CT检查,52例行3.0T MR检查,其中10例同时行CTA和MRA。DSA敏感度和准确度均为100%,双源CT敏感度与准确度分别为93.1%、97.2%.3.0T MR敏感度与准确度分别为89.1%、92.7%,三者的诊断敏感度和准确度均无显著性差异(P>0.05)。结论 双源CT、3.0T MR和DSA对颅内动脉瘤的诊断均具有较高的敏感度和准确度,无显著差异,但各具特点,三者合理利用具有更高的临床价值。更多还原

【Abstract】 Objective To evaluate the characteristics and clinical application value of Dual Source CT(DSCT),3.0T MR and DSA in the diagnosis of intracranial aneurysm.Methods The imaging characteristics of DSCT,3.0T MR and DSA in 102 patients of intracranial aneurysm were analyzed retrospectively.Results The cerebral DSA were performed in 102 patients,and the sensitivity and accuracy of DSA were 100%.60 patients were detected by DSCT/CTA,and the sensitivity and accuracy of DSCT/CTA were93.1% and 97.2% respectively.52 patients were detected by 3.0T MR/MRA,and the sensitivity and accuracy of 3.0T MR/MRA were 89.1 % and 92.7% respectively.10 patients were detected simultaneously by CT and MR.The diagnostic sensitivity and accuracy of these three methods had no significant difference(P>0.05).Conclusion The sensitivity and accuracy of DSCT,3.0T MR and DSA in the diagnosis of intracranial aneurysm are high and had no significant difference,each had its characteristic.Reasonable application of the three methods produces higher clinical value.更多还原
