标题
One major obstacle for MR-guided catheterizations is long acquisition times associated with visualizing interventional devices. Therefore, most techniques presented hitherto rely on single-plane imaging to visualize the catheter. 出版机构：Wiley Subscription Services, Inc., A Wiley Company 刊物名称：Magnetic Resonance in Medicine 出版时间：2010 ISSN：0740-3194 数据源：报刊文摘
MRI is of great clinical utility for the guidance of various diagnostic and therapeutic procedures. In a standard closed-bore scanner, the simplest approach is to manipulate the instrument outside the bore and move the patient into the bore for reference and control imaging only. 出版机构：Wiley Subscription Services, Inc., A Wiley Company 刊物名称：Magnetic Resonance in Medicine 出版时间：2010 ISSN：0740-3194 数据源：报刊文摘
Temperature estimation in proton resonance frequency (PRF) shift MR thermometry requires a reference, or pretreatment, phase image that is subtracted from image phase during thermal treatment to yield a phase difference image proportional to temperature change. 出版机构：Wiley Subscription Services, Inc., A Wiley Company 刊物名称：Magnetic Resonance in Medicine 出版时间：2010 ISSN：0740-3194 数据源：报刊文摘
Hypointense band artifacts occur at intersections of nonparallel imaging planes in rapidly acquired MR images; quantitative or numerical analysis of these bands and strategies to mitigate their appearance have largely gone unexplored. 出版机构：Wiley Subscription Services, Inc., A Wiley Company 刊物名称：Magnetic Resonance in Medicine 出版时间：2010 ISSN：0740-3194 数据源：报刊文摘
novel and fast approach for passive real-time tracking of interventional devices using paramagnetic markers, termed "projection-reconstruction imaging with echo-dephasing" (PRIDE) is presented. PRIDE is based on the acquisition of echo-dephased projections along all three physical axes. 出版机构：Wiley Subscription Services, Inc., A Wiley Company 刊物名称：Magnetic Resonance in Medicine 出版时间：2009 ISSN：0740-3194 数据源：报刊文摘
Objective To introduce a novel positive contrast method for passive localization and visualization of paramagnetic susceptibility markers.
出版机构：Springer Verlag 刊物名称：Magnetic Resonance Materials in Physics, Biology and Medicine 出版时间：2009 ISSN：0968-5243 数据源：报刊文摘
The use of the minimum stored energy current density map-based methodology of designing closed-bore symmetric superconducting magnets was described recently. 出版机构：Wiley Subscription Services, Inc., A Wiley Company 刊物名称：Magnetic Resonance in Medicine 出版时间：2010 ISSN：0740-3194 数据源：报刊文摘
The accurate visualization of interventional devices is crucial for the safety and effectiveness of MRI-guided interventional procedures. In this paper, we introduce an improvement to the visualization of active devices. 出版机构：Wiley Subscription Services, Inc., A Wiley Company 刊物名称：Magnetic Resonance in Medicine 出版时间：2010 ISSN：0740-3194 数据源：报刊文摘
It is shown here that tapered insulation dramatically improves the distal sensitivity of the loopless antenna by pushing the current sensitivity toward the tip. 出版机构：Wiley Subscription Services, Inc., A Wiley Company 刊物名称：Magnetic Resonance in Medicine 出版时间：2010 ISSN：0740-3194 数据源：报刊文摘
ificial heart valves comprising metal can cause significant MR image artifacts due to the material (susceptibility artifact) and/or electromagnetic characteristics (RF artifact). 出版机构：Informa Healthcare 刊物名称：Minimally Invasive Therapy & Allied Technologies 出版时间：2009 ISSN：1364-5706 数据源：报刊文摘
