Doppler US in interventional neuroradiology.
Doppler ultrasonography and transcranial Doppler ultrasonography can be applied to the study of the hemodynamic aspects of cerebrovascular disease curable with intravascular therapy. There are three stages where Doppler ultrasonography is considered appropriate: 1) in the diagnosis of cerebrovascular disease to study its hemodynamics and support the therapeutic approach; 2) during the interventional procedure to assess the hemodynamic modifications while therapy is administered; 3) in posttreatment control and in follow-up. The role and findings of transcranial Doppler ultrasonography and Doppler sonography in cerebral arteriovenous malformations, in dural arteriovenous malformations, in arteriovenous fistulae of large vessels in cerebral aneurysms and in steno-obstructive disease, are considered.
