Imaging of acute stroke - academia.cat
Transcranial Doppler ultrasonography can be used to assess the intracranial vasculature. This latter technique has been reviewed elsewhere14,15 and, since it does not allow visualization of the brain parenchyma, we will not discuss it further here. The purpose of this Review is to give clinicians an overview of the indications and

Transcranial ultrasonography may represent a valuable tool for patients with CVD in neurocritical care unit. However due to geographic, financial or patient tolerance of procedures, physicians may be limited to the tools they can utilize.
