Quantitative oxygenation venography from MRI phase.
PURPOSE To demonstrate acquisition and processing methods for quantitative oxygenation venograms that map in vivo oxygen saturation (SvO2 ) along cerebral venous vasculature. METHODS Regularized quantitative susceptibility mapping (QSM) is used to reconstruct susceptibility values and estimate SvO2 in veins. QSM with ℓ1 and ℓ2 regularization are compared in numerical simulations of vessel str...
متن کاملDevelopment, testing, and application of quantitative oxygenation imaging from magnetic susceptibility by MRI
The healthy brain consumes 20% of total oxygen used by the body under normal conditions. Continuous oxygen delivery to neural tissue is needed to maintain normal brain function and viability. Reliable measurements of brain oxygenation can provide critical information to diagnose and manage diseases in which this oxygen supply is disturbed, including stroke and tumor. In acute stroke, for instan...
متن کاملSubtraction MR Venography Acquired from Time-Resolved Contrast-Enhanced MR Angiography: Comparison with Phase-Contrast MR Venography and Single-Phase Contrast-Enhanced MR Venography
OBJECTIVE To evaluate the image characteristics of subtraction magnetic resonance venography (SMRV) from time-resolved contrast-enhanced MR angiography (TRMRA) compared with phase-contrast MR venography (PCMRV) and single-phase contrast-enhanced MR venography (CEMRV). MATERIALS AND METHODS Twenty-one patients who underwent brain MR venography (MRV) using standard protocols (PCMRV, CEMRV, and ...
متن کاملBlood oxygenation level-dependent MRI for assessment of renal oxygenation
Blood oxygen level-dependent magnetic resonance imaging (BOLD MRI) has recently emerged as an important noninvasive technique to assess intrarenal oxygenation under physiologic and pathophysiologic conditions. Although this tool represents a major addition to our armamentarium of methodologies to investigate the role of hypoxia in the pathogenesis of acute kidney injury and progressive chronic ...
متن کاملHigh Resolution Functional MR Venography with 7T MRI
Magnetic resonance venography (MRV) has been used to assess the effects of medical treatment for and the resolution of cerebral venous diseases. The contrast mechanism involving MRV used for functional or anatomical applications has been based on the local magnetic field inhomogeneity created by deoxyhemoglobin, which determines MR signal intensity [1,2]. Susceptibility weighted imaging (SWI), ...
