Why the study?
Does power Doppler imaging (PDI) improve the evaluation of normal and pathological vertebral arteries compared to conventional color Doppler flow imaging (CDFI) in patients with suspected posterior circulation ischemia?
Population
49 patients with signs and symptoms suggesting ischemia within the posterior circulation
Comparison
Power Doppler imaging (PDI) vs Conventional color Doppler flow imaging (CDFI)
Design
Cross-sectional

May aid vertebral artery assessment in posterior ischemia; leaves open prospective validation against angiography.
Does power Doppler imaging (PDI) improve the evaluation of normal and pathological vertebral arteries compared to conventional color Doppler flow imaging (CDFI) in patients with suspected posterior circulation ischemia?
Combined use of power Doppler imaging and color Doppler flow imaging provides high sensitivity and specificity for assessing vertebral artery disease, increasing diagnostic confidence.
