Power Doppler imaging: initial evaluation as a screening examination for carotid artery stenosis
Dates to which data relate Effectiveness data in the principal pilot study corresponded to patients examined between April and September 1997. Effectiveness data in the validation pilot study corresponded to patients examined between May and October 1997. Some effectiveness data were based on assumptions from two studies published in 1995 and 1997. Resource consumption data were based on a surv...

متن کاملPower Doppler imaging: initial evaluation as a screening examination for carotid artery stenosis.
PURPOSE To evaluate power Doppler imaging as a possible screening examination for carotid artery stenosis. MATERIALS AND METHODS In the principal pilot study, a prospective, blinded comparison of power Doppler imaging with duplex Doppler imaging, the reference-standard method, was conducted in 100 consecutive patients routinely referred for carotid artery imaging at a large, private multispec...
متن کاملDetection of coronary artery stenosis with power Doppler imaging.
BACKGROUND Power Doppler is a new imaging method for detecting microbubbles during myocardial contrast echocardiography (MCE) based on the registration of variance resulting from ultrasound-induced nonlinear bubble behavior. We tested the hypothesis that power Doppler imaging can be used to quantify coronary stenoses. METHODS AND RESULTS Three left anterior descending (LAD) coronary stenoses ...
متن کاملA comparison of Power Doppler with conventional sonographic imaging for the evaluation of renal artery stenosis
BACKGROUND Power Doppler (PD) has improved diagnostic capabilities of vascular sonography, mainly because it is independent from the angle of insonation. We evaluated this technique in a prospective comparison with conventional imaging, consisting in Duplex and Color Doppler, for the evaluation of Renal Artery (RA) stenosis. METHODS Sensitivity, specificity and predictive values of PD and con...
