Half-dose Coronary Artery Calcium Scoring: Impact of Iterative Reconstruction
Purpose:
The purpose of this study was to assess the impact of adaptive statistical iterative reconstruction (ASiR) on half-dose coronary artery calcium scoring (CACS) acquisition protocol.
Materials and Methods:
Between September 2016 and October 2017, 89 patients (54 male patients, mean age 64.6±10.7 y) with a clinically indicated coronary computed tomography angiography were prospectively enrolled. On a 64-row computed tomography scanner, patients underwent a standard CACS protocol (120 kVp, 170 mAs) reconstructed by filtered-back projection, and a half-dose CACS protocol (120 kVp, 85 mAs) reconstructed ...

Current Evidence in Cardiothoracic Imaging: Computed Tomography–derived Fractional Flow Reserve in Stable Chest Pain
High-accuracy diagnostic imaging is needed to diagnose and manage coronary artery disease as well as to allow risk stratification for future events. Advancements in multidetector computed tomography and image postprocessing allow for routine computed tomography coronary angiography to provide anatomic luminal assessment similar to invasive coronary angiography, and, similarly, computational fractional flow reserve derived from computed tomography facilitates determination of hemodynamically relevant stenosis comparable to invasive fractional flow reserve. In this review article, we describe the diagnostic performance and t...

Current Evidence in Cardiothoracic Imaging: Growing Evidence for Coronary Computed Tomography Angiography as a First-line Test in Stable Chest Pain
Coronary computed tomography angiography (CCTA) is a validated technique for the evaluation of patients with suspected coronary artery disease, showing high accuracy compared with invasive coronary angiography and high negative predictive value. CCTA is also well positioned as a first-line test for the evaluation of stable chest pain. This purpose of this review is to examine the evidence behind CCTA in the setting of stable chest pain, with attention to 5 key strengths of a CCTA-based approach: (1) effective gatekeeping to cardiac catheterization, (2) selective discrimination for revascularization and tailored medical the...
