Photon-Counting CT Versus Conventional CT for Carotid Plaque Assessment in Patients With Carotid Artery Stenosis
Prospective Comparison of Photon-Counting Detector CT and Conventional Energy-Integrating Detector CT for Carotid Atherosclerotic Plaque Assessment in Patients With Carotid Artery Stenosis
Studieöversikt
Status
Detaljerad beskrivning
This prospective observational study aims to compare photon-counting detector computed tomography angiography (PCD-CTA) with conventional energy-integrating detector computed tomography angiography (EID-CTA) for the assessment of carotid atherosclerotic plaques in patients with carotid artery stenosis.
The study will evaluate differences between the two CT techniques in the visualization and quantitative characterization of carotid plaques, including plaque morphology, plaque burden, plaque components, calcification-related artifacts, and degree of carotid artery stenosis. Objective and subjective image quality will also be compared.
The study is intended to determine whether the improved spatial resolution and spectral imaging capabilities of photon-counting CT provide advantages over conventional CT for the characterization of carotid atherosclerotic disease.

Patients With Carotid Artery Stenosis
Patients with carotid artery stenosis who undergo preprocedural carotid CT angiography will be prospectively enrolled.
Carotid plaque characteristics and image quality will be evaluated and compared between photon-counting detector CT angiography and conventional energy-integrating detector CT angiography.

Contrast-to-noise ratio on PCD-CTA compared with conventional EID-CTA
Tidsram: 1-4years
