The aim of this paper of the symposium of the 36th Scientific Meeting of Japanese Society of Neurology is to clarify the general status of ultrasonic assessment in the imaging modality of cerebrovascular disease (CVD). Although there are many ultrasonic techniques, we want to address the carotid ultrasonography and transcranial ultrasonography. Cervical carotid atherosclerosis is known to be a major cause of brain infarction and Duplex ultrasonography is the best imaging tool. This method made it possible to visualize the living human arterial wall and to visualize the intraplaque characters. This was most advantage among several modalities. Few and really disadvantages of this method are examiner dependent results and narrow visual window. On the basis of these ultrasonic data, many investigations of nature of stroke have been performed. Transcranial ultrasonography have been accepted as a new method for non-invasive intracranial vascular imaging. There are the transcranial Doppler, transcranial tomography and the transcranial color flow imaging. Using these transcranial methods, we can evaluate the intracranial lesions. Transcranial color flow imaging made it possible to obtain real images of major arteries of circle of Willis. In conclusion, ultrasonic modality is a useful tool for assessing the risk of cerebrovascular disease or atherosclerosis, especially in chronic situations.
本文是日本神经学会第36届科学会议研讨会论文，旨在阐明脑血管疾病（CVD）成像模式中超声评估的总体状况。虽然有许多超声技术，但我们想重点探讨颈动脉超声检查和经颅超声检查。颈动脉硬化是脑梗死的主要原因，双功超声检查是最佳成像工具。该方法能够可视化活体人类动脉壁并观察斑块内特征。这是几种检查方式中最具优势的。该方法较少且真正的缺点是结果依赖检查者以及可视窗口狭窄。基于这些超声数据，已经开展了许多关于中风本质的研究。经颅超声检查已被公认为一种无创颅内血管成像的新方法。包括经颅多普勒、经颅断层扫描和经颅彩色血流成像。使用这些经颅方法，我们可以评估颅内病变。经颅彩色血流成像能够获取 Willis 环主要动脉的真实图像。总之，超声检查方式是评估脑血管疾病或动脉粥样硬化风险的有用工具，尤其是在慢性情况下。
