Non invasive evaluation in cerebrovascular study: possibility and prospects.
The authors outline the importance of the global investigation of the cerebrovascular system in order to obtain more exact information about the ethiopathology of vascular ischaemic brain disease. Each patient is always submitted to the following investigations: Duplex scanner of epiaortic vessels, Transcranial doppler and echocardiographic screening in our vascular laboratory; moreover, when haemodynamic carotid artery stenosis is present, duplex scanner of femoro-popliteal vessels and microcirculatory study of the brain with Zenon133, via inhalation, were undertaken. In the second part of the study the authors refer a relationship between the instrumental doppler signal and the real risk evidenced by techniques which can provide information on the composition, structure and stability of the plaques and correlate this information with the data from the doppler analysis. Instrumental techniques such as thermal analysis, atomic absorption spectroscopy, ICP analysis and IR spectroscopy were used to carry out this study.
