Spectral Photon-Counting Detector CT for Comprehensive Evaluation of Carotid Plaque and Stenosis

Key Points

This research aims to evaluate the effectiveness of low-energy photon-counting detector CT reconstructions in assessing carotid plaque and stenosis.
Utilized low-energy photon-counting detector CT (PCD-CT) for imaging
Compared PCD-CT reconstructions against traditional methods
Assessed plaque and stenosis measurements
Evaluated performance with respect to MRI and histology
PCD-CT reconstructions improved contrast-to-noise ratio (CNR) and sharpness
Consistent plaque and stenosis measurements were maintained
The PL algorithm demonstrated potential for better assessment of calcified plaques
Conventional methods were found to overestimate stenosis in some cases

Abstract

Low-energy PCD-CT reconstructions enhance CNR and sharpness while maintaining consistent plaque and stenosis measurements. The PL algorithm may improve the assessment of calcified plaques, where conventional reconstructions may overestimate stenosis. PCD-CT shows promise for advanced plaque composition evaluation, but further validation against MRI and histology is warranted.
