CT Angiography Vs. Duplex: Evaluating Carotid Stenosis Flow

A recent study published in 3D Print Med compared CT angiography with duplex sonography using a hemodynamic phantom that simulates carotid stenosis. The research demonstrated that CT angiography delivers high‑resolution three‑dimensional anatomical detail, whereas duplex sonography excels at real‑time blood‑flow measurement. Discrepancies between the two modalities underscore the necessity of a combined diagnostic strategy to improve treatment planning. The findings aim to refine clinical decision‑making and reduce stroke risk in patients with carotid artery disease.
