Evaluation of low-dose chest scans for coronary artery calcium scoring using photon-counting computed tomography with different slice thicknesses and iterative reconstruction levels.

ABSTRACT:

Background

Coronary artery calcium scoring (CACS) is a noninvasive method for quantifying coronary artery calcification plaque burden. Although low-dose chest computed tomography (LD-CT) scans with energy-integrating detector CT can be used for CACS, its clinical utility is constrained by higher mean differences and wider limits of agreement. In contrast, photon-counting CT offers significantly enhanced image quality compared to energy-integrating detector CT, making it a more promising tool for accurate CACS. This study investigated the difference in CACS obtained from LD-CT using photon-counting detector CT as compared to standard CACS CT (CAC-CT).

Methods

This prospective study included 105 patients (mean age 64.6±11.5 years) who underwent both CAC-CT and LD-CT scans on t
