320排640层动态容积CT颅脑一站式检查对颅内动脉瘤的诊断价值

目的 探讨320排640层动态容积CT颅脑一站式检查对颅内动脉瘤的诊断价值.方法 对104例自发性蛛网膜下腔出血(SAH)患者行CT颅脑一站式检查和数字减影血管造影(DSA)检查,判断有无动脉瘤及对动脉瘤的定性定量进行评价.结果 DSA确诊动脉瘤93例,CT颅脑一站式检查均确诊,诊断符合率为100%.DSA共发现动脉瘤126个,CT颅脑一站式检查发现125个,检查敏感性为99.20%.CT颅脑一站式检查对动脉瘤的诊断与DSA有高度的一致性.结论 320排640层动态容积CT颅脑一站式检查能够准确对颅内动脉瘤进行定性、定量评价,操作简单、快速,可作为颅内动脉瘤检查的首选方法.

Diagnostic Application of One-stop-Shop Procedure with 320-Detector Row 640 Dynamic Volume CT System in Patients with Cerebral Aneurysm

Objective To investigate the diagnostic value of 320 row 640 layer dynamic volumetric CT brain one-stop-shop procedure for intracranial aneurysms patients.Methods 104 patients with spontaneous subarachnoid hemorrhage underwent 320 row 640 layer dynamic volumetric CT and DSA check to dectect aneurysm and to make a quantitative and qualitative evaluation.Results 93 aneurysm patients were detected by DSA,and the specificity of CT was 100%.126 aneurysms were detected by DSA,however 125 by CT and the sensitivity was 99.20%.The results of CT and DSA had high degree consistency.Conclusion Cerebral aneurysm can be accurately diagnosed by 320 row 640 layer dynamic volumetric CT brain one-stop-shop procedure,and should be preferred in diagnosis of aneurysm.
