用经颅多普勒超声对64例偏头痛患者，其中典型偏头痛21例，普通偏头痛43例进行研究，结果表明其颅内血流动力学改变，不仅表现在血流速度的加快、减慢、不稳定、不对称，而且伴有血流杂音及血流频谱异常，基于上述结果，我们认为血流杂音和血流频谱异常可以作为偏头痛的诊断依据之一。 Transcranial Doppler ultrasound in 64 cases of migraine patients, including a typical migraine in 21 cases, 43 cases of common migraine headache, the results show that changes in intracranial hemodynamics, not only in the blood flow faster, less Slow, unstable, asymmetric, and accompanied by abnormal flow noise and abnormal blood flow spectrum, based on the above results, we believe that abnormal flow noise and blood flow spectrum can be used as a diagnosis of migraine one of the bases.
