Depth ranges for detecting anterior and posterior circulation vessels were derived from power motion transcranial Doppler flow tracks and computed tomography angiography images of the circle of Willis.

A total of 229 Power motion Doppler computed tomography angiography vessel pairs were analysed. Power motion transcranial Doppler tracks for M1 and proximal M2 middle cerebral artery (MCA) were located at 24\u201368 mm (M1 MCA: 36\u201368 mm; M2 MCA: 24\u201353 mm); anterior cerebral artery (ACA): 50\u201378 mm; P1 posterior cerebral artery (PCA): 50\u201374 mm; left vertebral artery: 30\u201374 mm; right vertebral artery: 30\u201378 mm; basilar artery: 76\u2013106 mm. The per cent agreement of power motion Doppler-transcranial Doppler for identifying proximal intracranial arteries compared to computed tomography angiography was: M1 and M2 MCA: 100% (95% confidence interval: 96\u2013100%); M1 MCA: 98% (95% confidence interval: 86\u2013100%); M2 MCA: 94% (95% confidence interval: 79\u201399%); A1 ACA: 82% (95% confidence interval: 68\u201391%); P1 PCA: 70% (95% confidence interval: 53\u201383%); left vertebral artery: 96% (95% confidence interval: 80\u2013100%); right vertebral artery: 96% (95% confidence interval: 79\u2013100%); basilar artery: 100% (95% confidence interval: 89\u2013100%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Power motion transcranial Doppler intercepts proximal vessels with good-to-excellent agreement with computed tomography angiography.
