Cerebral Hypoperfusion at Transcranial Color-Coded Doppler.

As part of the clinical practice, the examination will be performed with ultrasound machines that have presets for TCCD, using a low-frequency sector probe (2-25 MHz) with a transtemporal approach to obtain a scan through the midbrain plane. Through the use of Color Doppler and Pulsed-Wave Doppler, a spectral doppler waveform of the M1 segment of the middle cerebral artery velocity is obtained bilaterally. If hypoperfusion signs are discovered, TCCD will be repeated to assess the effects of each intervention.
