Evaluation of Metal Artifact Reduction software in Computed Tomography
Introduction: The image quality of computed tomography (CT) can be seriously lowered by metal implants of patients. These implants are known to exert a significant impact on diagnostic accuracy due to artifacts. The current study aimed to assess the usefulness of Metal Artifact Reduction (MAR) software in the reduction of metal artifacts, in comparison to iterative rec...
متن کاملCT Dental Artifact: Comparison of an Iterative Metal Artifact Reduction Technique with Weighted Filtered Back-Projection
Background Dental hardware produces streak artifacts on computed tomography (CT) images reconstructed with the standard weighted filtered back projection (wFBP) method. Purpose To perform a preliminary evaluation of an iterative metal artifact reduction (IMAR) technique to assess its ability to improve anatomic visualization over wFBP in patients with dental amalgam or other hardware. Mater...
متن کاملDesaturation during Onyx embolization.
Editor—The Onyx Liquid Embolic System (Onyx; Micro Therapeutics, Inc., Irvine, CA, USA) is a new non-adhesive liquid embolic agent and is currently being used at our institution in the embolization of cerebral vascular lesions. The disadvantage of Onyx is that it is dissolved in dimethyl sulphoxide (DMSO). Systemic toxicity, such as pulmonary oedema, bronchospasm, bradyarrhythmia, and even card...
متن کاملRetained Microcatheter after Onyx Embolization of Intracranial Arteriovenous Malformation
Endovascular embolization is being increasingly used to treat intracranial arteriovenous malformations (AVMs). However, we experienced two patients with retained microcatheters after AVM embolization using Onyx.
متن کاملBrain AVM embolization with Onyx.
BACKGROUND AND PURPOSE To report the initial experience by using a new liquid embolic agent (Onyx) for embolization of brain arteriovenous malformations (AVMs). METHODS Between May 2000 and December 2005, 44 patients with brain AVMs were embolized with Onyx. There were 18 women and 26 men with a mean age of 42.4 years (median 44, range 14-71 years). Clinical presentation included seizures in ...
