Software-based automated measurement of susceptibility artifacts on magnetic resonance images

چکیده
Introduction: MR-compatible implants and instruments for interventions under MR-imaging can cause susceptibility artifacts [1, 2]. Before clinical diagnostics or intervention, it must be known in what extent those artifacts could overlay the tissue of interest. For that reason, ASTM developed the standard F2119 [2] which describes how to determine the artifact’ size of passive implants. The standard defines precisely a susceptibility artifact, but gives only a vague method for artifact measurement. This had led to different methods to determine the greatest artifact, such as the categorization [3] and the assessment with measurement tools [4]. The objective was to develop a platformindependent software system for rapid, objective and reproducible measurement of susceptibility artifacts that complying with ASTM.

متن کاملComparison of Two Quantitative Susceptibility Mapping Measurement Methods Used For Anatomical Localization of the Iron-Incorporated Deep Brain Nuclei
Introduction Quantitative susceptibility mapping (QSM) is a new contrast mechanism in magnetic resonance imaging (MRI). The images produced by the QSM enable researchers and clinicians to easily localize specific structures of the brain, such as deep brain nuclei. These nuclei are targets in many clinical applications and therefore their easy localization is a must. In this study, we aimed to i...

Background: Brain tissue segmentation for delineation of 3D anatomical structures from magnetic resonance (MR) images can be used for neuro-degenerative disorders, characterizing morphological differences between subjects based on volumetric analysis of gray matter (GM), white matter (WM) and cerebrospinal fluid (CSF), but only if the obtained segmentation results are correct. Due to image arti...
متن کاملAccelerating Magnetic Resonance Imaging through Compressed Sensing Theory in the Direction space-k
Magnetic Resonance Imaging (MRI) is a noninvasive imaging method widely used in medical diagnosis. Data in MRI are obtained line-by-line within the K-space, where there are usually a great number of such lines. For this reason, magnetic resonance imaging is slow. MRI can be accelerated through several methods such as parallel imaging and compressed sensing, where a fraction of the K-space lines...
