彩色多普勒能(CDE)或“动力型”多普勒是一种独特且对血流运动非常敏感的新的彩色多普勒超声技术,用于脑血管造影前蛛网膜下腔出血(SAH)病人颅内动脉瘤的鉴别诊断。与众多的传统的彩色多普勒相比它能显示更多更小的颅内动静脉。 作者在5个月时间内观察了40例接受脑血管造影和经颅多普勒(TCD)超声检查的患者,31例确诊为动脉瘤。血管造影发现该31例患者有37个动脉瘤,9例未见动脉瘤。在CDE检查中,37个动脉瘤检查发现35个,漏诊3个,假阳性1例。其漏诊原因
Color Doppler (CDE) or “powered” Doppler is a unique color Doppler ultrasound technology that is very sensitive to blood flow and is used for pre-angiographic subarachnoid hemorrhage (SAH ) Differential diagnosis of intracranial aneurysms in patients. Compared with many traditional color Doppler, it can show more and smaller intracranial arteries and veins. The authors observed 40 patients undergoing cerebral angiography and transcranial Doppler (TCD) ultrasonography in 5 months, and 31 patients were diagnosed as aneurysms. Angiography showed that the 31 patients had 37 aneurysms and 9 had no aneurysms. In CDE examination, 37 aneurysms were found in 35 examinations, 3 missed examinations and 1 false-positive. The reason for missed diagnosis
