Coronary MR Angiography in patients with coronary artery disease using image-based respiratory motion compensation
نویسندگان
چکیده
Background Respiratory motion remains a major impediment in a substantial amount of patients undergoing coronary magnetic resonance angiography (CMRA). Studies in healthy subjects have shown that image-based navigation (iNAV) improves respiratory motion compensation compared to the state-of-the art method. Here, we used iNAV for respiratory motion compensated CMRA in 22 patients with known or suspected coronary artery disease.

PURPOSE The purpose of this study was to evaluate a new inline motion compensation approach called image-based navigation with Constant Respiratory efficiency UsIng Single End-expiratory threshold (iNAV-CRUISE) for coronary MR angiography (CMRA). METHODS The CRUISE gating technique was combined with iNAV motion correction and implemented inline for motion-compensated CMRA on a 1.5 Tesla scann...
متن کاملAdvanced Respiratory Motion Compensation for Coronary MR Angiography
Despite technical advances, respiratory motion remains a major impediment in a substantial amount of patients undergoing coronary magnetic resonance angiography (CMRA). Traditionally, respiratory motion compensation has been performed with a one-dimensional respiratory navigator positioned on the right hemi-diaphragm, using a motion model to estimate and correct for the bulk respiratory motion ...

متن کاملDiagnosis of Coronary Artery Disease using Neuro-fuzzy-based Method
Background & Aim: Coronary artery disease is one of the most common diseases in different societies. Coronary angiography is established as one of the best methods for diagnosis of this disease. Angiography is an invasive and costly method. Furthermore, it is associated with risks such as death, heart attack, and stroke. Thus, this study introduces a neuro-fuzzy-based method which can help the ...
