虽然经颅多普勒检查获得的速度波形的形状可以指示颅内压升高和近端动脉损害等异常，异常波形形态的意义往往是模糊的。在这份报告中，我们描述了四个病例，其中一个不寻常的波形形态获得的血管扭曲和狭窄的颅内肿块。因此，经颅多普勒检查中出现这种不寻常的形态作为孤立信号，对解释经颅多普勒研究的人来说，这表明受声血管的结构变形。
Although the shapes of velocity waveforms obtained with transcranial Doppler examination can indicate such abnormalities as increased intracranial pressure and proximal arterial compromise, the significance of unusual waveform morphologies is often obscure. In this report, we describe four cases in which an unusual waveform morphology was obtained from vessels distorted and narrowed by intracranial masses. The appearance of this unusual morphology as an isolated signal within a transcranial Doppler examination should, therefore, suggest a structural deformation of the insonated vessel to those who interpret transcranial Doppler studies.
