In x‐ray computed tomography (CT), materials with different elemental compositions can have identical CT number values, depending on the mass density of each material and energy detected beam. Differentiating classifying tissue types contrast agents thus be extremely challenging. multienergy CT, one or more additional attenuation measurements are obtained at a second, third energy. This allows differentiation least two materials. Commercial dual‐energy systems (only measurements) now...
Purpose: To develop a consensus standard for quantification of coronary artery calcium (CAC). Materials and Methods: A CAC was developed by multi-institutional, multimanufacturer international consortium cardiac radiologists, medical physicists, industry representatives. This report specifically describes the standardization scan acquisition reconstruction parameters, use patient size–specific tube current values to achieve prescribed image noise, mass score eliminate scanner- size–based...
Atrial fibrillation (AF) has been linked to inflammatory factors and obesity. Epicardial fat is a source of several mediators related the development coronary artery disease. We hypothesized that periatrial may have similar role in AF.
This study sought to determine updated conversion factors (k-factors) that would enable accurate estimation of radiation effective dose (ED) for coronary computed tomography angiography (CTA) and calcium scoring performed on 12 contemporary scanner models current clinical cardiac protocols compare these methods the standard chest k-factor 0.014 mSv·mGy−1cm−1. Accurate ED from CT scans is essential meaningfully benefits risks different imaging strategies optimize test protocol selection....
AimsAlthough multislice computed tomography (MSCT) detects obstructive coronary artery disease (CAD) with high diagnostic accuracy, there is a paucity of long-term prognostic data. We sought to assess the incremental value 64-slice CT in patients suspected but no documented CAD.
Non-invasive identification and characterization of mildly stenotic atherosclerotic lesions is an increasingly important focus coronary imaging.We examined the accuracy multi (16)-slice computed tomography (MSCT) for imaging these in comparison with intravascular ultrasound (IVUS).Mildly segments left artery were identified by angiography analyzed using IVUS contrast-enhanced MSCT. Independent reviewers evaluated MSCT presence, composition distribution plaque remodeling response to receiver...
Current guidelines and literature on screening for coronary artery calcium cardiac risk assessment are reviewed both general special populations. It is shown that populations a zero score excludes most clinically relevant disease. The importance of standardization measurements by multidetector CT discussed.
Advances in scanner technology enabling shorter scan times, improvements spatial and temporal resolution, more dose-efficient data reconstruction coupled with rapidly growing evidence from clinical trials have established computed tomography (CT) as an important imaging modality the evaluation of cardiovascular disorders. Multienergy (or spectral or dual-energy) CT is a relatively recent advance which attenuation different energies are used to characterize materials beyond what possible at...
Spectral detector computed tomography (SDCT) is a novel technology that uses two layers of detectors to simultaneously collect low and high energy data. data used generate conventional polyenergetic images as well dedicated spectral including virtual monoenergetic material composition (iodine-only, unenhanced, effective atomic number) images. This paper provides an overview SDCT description some image types. The potential utility for cardiovascular imaging the impact this new on radiation...
