Correction of phase offset errors in cardiovascular magnetic resonance using background subtraction from stationary tissue
Introduction Phase offset errors from local eddy currents can lead to significant errors in flow assessment on clinical cardiovascular magnetic resonance (CMR) examinations. Phantom correction for phase contrast (PC) errors appears to improve accuracy in flow assessment, but requires additional time and is not free from technical limitations. Background subtraction using a region of stationary ...
متن کاملAnalysis of temperature dependence of background phase errors in phase-contrast cardiovascular magnetic resonance
BACKGROUND The accuracy of phase-contrast cardiovascular magnetic resonance (PC-CMR) can be compromised by background phase errors. It is the objective of the present work to provide an analysis of the temperature dependence of background phase errors in PC-CMR by means of gradient mount temperature sensing and magnetic field monitoring. METHODS Background phase errors were measured for vario...
متن کاملTissue Selective Magnetic Resonance Subtraction Venography
We have developed a procedure to image the major veins of the brain using three dimensional magnetic resonance imaging sequences. This procedure is based on the selective enhancement of blood vessels following intravenous administration of contrast media such as gadolinium. A simple subtraction is performed between the post-contrast and pre-contrast MR images after correcting for overall intens...
متن کاملMyocardial tissue tagging with cardiovascular magnetic resonance
Cardiovascular magnetic resonance (CMR) is currently the gold standard for assessing both global and regional myocardial function. New tools for quantifying regional function have been recently developed to characterize early myocardial dysfunction in order to improve the identification and management of individuals at risk for heart failure. Of particular interest is CMR myocardial tagging, a ...
