We compared stenosis degree obtained with different modalities against vascular imaging gold standard, intravascular ultrasound, IVUS.<h4>Methods</h4>300 consecutive patients (age 47-83 years, 192 men, 64% asymptomatic) with carotid artery stenosis of " ≥ 50%" referred for potential revascularization received as per study protocol (i) duplex ultrasound (DUS), (ii) computed tomography angiography (CTA), (iii) intraarterial quantitative angiography (iQA) and (iv) and (iv) IVUS. Correlation of measurements with IVUS (r), proportion of those concordant (within 10%) and proportion of under/overestimated wereThe international journal of cardiovascular imaging1909-1920https://www.ebi.ac.uk/biostudies/studies/S-EPMC10589130biostudies-literatureImaging modality-dependent carotid stenosis severity variations against intravascular ultrasound as a reference: Carotid Artery intravasculaR Ultrasound Study (CARUS).PMC10589130Dabrowski WStefaniak JPieniazek PMusialek PMoczulski ZPaluszek PTekieli LMazurek ADzierwa KKablak-Ziembicka AUrbanczyk-Zawadzka MKrupinski MPrzewlocki TfalseImaging modality-dependent carotid stenosis severity variations against intravascular ultrasound as a reference: Carotid Artery intravasculaR Ultrasound Study (CARUS).<h4>Purpose</h4>Different non-invasive and invasive imaging modalities are used to determine carotid artery stenosis severity that remains a principal parameter in clinical decision-making.
