✦ Synopsis
Unlike conventional transcranial Doppler (TCD), transcranial color-coded sonography (TCCS) enables imaging of the basal cerebral arteries using color-flow ultrasonography and correction for the angle of insonation when determining blood flow velocities. We present hemodynamic data from 20 normal subjects, each studied with TCD and TCCS.
Velocities derived using TCCS with angle correction were significantly greater than those derived using TCD in all vessels (mean velocities [cmlsec; mean with 95% confidence intervals])-anterior cerebral artery:
