摘要
目的:研究联合应用16排螺旋CTA及3D-DSA在颅内动脉瘤的诊断及治疗中的临床应用价值。方法:将27例高度怀疑颅内动脉瘤患者的16排螺旋CTA及3D-DSA检查结果与外科手术治疗的最终结果进行对比,评价16排螺旋CTA及3D-DSA在动脉瘤的检出率、三维形态与空间关系的显示能力。研究联合应用16排螺旋CTA及3D-DSA在颅内动脉瘤的诊断及治疗价值。结果:27例疑似患者有25例经外科手术治疗证实为动脉瘤,发现动脉瘤28个。16排螺旋CTA及3D-DSA动脉瘤的诊断率上无明显差异。16排螺旋CTA对检出的动脉瘤可准确清楚地显示其三维形态及与周围颅骨的空间关系,3D-DSA对颅内动脉瘤的瘤颈、瘤体及动脉瘤与载瘤动脉关系显示清楚、准确。结论:在颅内动脉瘤影像学诊断上,16排螺旋CTA和3D-DSA各有优势,两种检查方法互补可提高动脉瘤的检出率。联合应用16排螺旋CTA及3D-DSA可为手术设计提供极大参考。
Objective:To research three-dimensional computed tomography angiography 16-slice CTA combined three-dimensional digital subtraction angiography(3D-DSA)in the diagnosis of intracranial aneurysms.Methods:16-slice CTA and 3D-DSA were performed in 27 cases with highly suspected in patients with intracranial aneurysms,and compared with the final outcome by surgery.Evaluation of 16-lide CTA and3D-DSA in the detection rate of aneurysms.three-dimensionaI shape and spatialrelations ability to display.Research16-slice CTA combined 3D-DSA in the diagnosis of intracranial aneurysms.Results:27 cases of suspected patients,25 cases of surgical treatment of confirmed aneurysms.28 aneurysms found.16-slice CTA and3D-DSA for detection rate of aneurysms was no significant difference.16-slice CTA of the aneurysm can be accurately detected clearly shows its three-dimensional shape and spatial relationship with the surrounding skull.Aneurysm neck,the tumor body and the aneurysm and parent artery relationship are disfulaued clearly and accurately by 3D-DSA.Conclusions:Imaging of intracranial aneurysm diagnosis,16-slice CTA and 3D-DSA havetheir respective advantages.Combined two methods can improve the detection rate ofaneurysms.16-slice CTA combined 3D-DSA have suppod of design for operation.
