Metal Artifact–Free and Dose-Efficient Computed Tomography Imaging of a Cardiac Prosthetic Valve Using Spectral Shaping of the X-ray Beam: A Case Report

Metal Artifact–Free and Dose-Efficient Computed Tomography Imaging of a Cardiac Prosthetic Valve... Abstract Bioprosthetic valve (BPV) thrombosis can be challenging to diagnose with cardiac computed tomography owing to metal artifacts of the BPV. In this case report, an optimized metal artifact reduction protocol using a third-generation dual-source multidetector computed tomographic scanner with high kVp (Sn150kVp) and tin (Sn) filtration and high temporal resolution yielded high-quality, artifact-free, dynamic images of a thrombosed mitral BPV. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Computer Assisted Tomography Wolters Kluwer Health

Abstract

Abstract Bioprosthetic valve (BPV) thrombosis can be challenging to diagnose with cardiac computed tomography owing to metal artifacts of the BPV. In this case report, an optimized metal artifact reduction protocol using a third-generation dual-source multidetector computed tomographic scanner with high kVp (Sn150kVp) and tin (Sn) filtration and high temporal resolution yielded high-quality, artifact-free, dynamic images of a thrombosed mitral BPV.
