The use of transcranial color-coded duplex sonography in a cat with suspected cerebral ischemia

      Transcranial color-coded duplex Doppler sonography (TCCD) is a commonly used tool in human medicine for neuro-intensive monitoring (

      ). TCCD allows obtaining and analyzing Doppler flow curve of the artery under evaluation and identifying the systolic peak flow velocity (Vp) and end-diastolic flow velocity (Ved), measures used to calculate the resistance index (RI) using the formula:
      RI = (Vp – Ved) / Vp
