Three-Dimensional Myocardial Perfusion MRI Using SW-CG-HYPR
Introduction: First-pass perfusion MRI is a promising technique for detecting ischemic heart disease. However, the diagnostic value of the method is limited by the low spatial coverage, resolution, SNR, and cardiac motion related image artifacts. Parallel imaging methods have been applied in myocardial perfusion MRI, but the spatial coverage and SNR remain limited. Time-resolved data acquisitio...
متن کاملMyocardial Perfusion MRI Using SW-CG-HYPR in Canines with Improved Spatial Coverage, Resolution and SNR
SW-CG-HYPR and the conventional methods. The delineation of the myocardial territories supplied by LCX stenoses in SW-CG-HYPR images is clearly improved as compared to the reference images. Figure 3. Comparison of the signal changes vs. time curves between SW-CG-HYPR and reference methods in a dog study. Figure 1. Schematic of the perfusion data acquisition structure: (a) Conventional SR prepar...
متن کاملMyocardial perfusion MRI using SW-CG-HYPR for the detection of coronary artery disease
In this work, we have prospectively examined the diagnostic value of adenosine-induced stress myocardial perfusion MRI using SW-CG-HYPR in 50 patients with suspected CAD. Using the high-resolution, whole left ventricle SW-CG-HYPR method, perfusion MRI was able to depict hemodynamically relevant coronary artery stenosis with an accuracy of 90% and 93% based on perpatient and per-vessel analyses,...
متن کاملFree-breathing myocardial perfusion MRI using SW-CG-HYPR and motion correction.
First-pass perfusion MRI is a promising technique to detect ischemic heart disease. Sliding window (SW) conjugate-gradient (CG) highly constrained back-projection reconstruction (HYPR) (SW-CG-HYPR) has been proposed to increase spatial coverage, spatial resolution, and SNR. However, this method is sensitive to respiratory motion and thus requires breath-hold. This work presents a non-model-base...
متن کاملSW-Architektur, SW-Sharing & Standardisierung
Die Zusammenarbeitsmodelle in der Automotive Software Domäne werden immer komplexer und flexibler. Die Auftraggeber (hier ein OEM) von Steuergeräten entwickeln immer mehr Software-Teile selbst und stellen sie dem Zulieferer (hier ein Tier1) zur Integration zur Verfügung. Unter bestimmten Voraussetzungen geht es aber auch in die umgekehrte Richtung: Software, die vom Tier1 entwickelt wurde, wird...
