Quantitative myocardial perfusion analysis with a dual-bolus contrast-enhanced first-pass MRI technique in humans.
PURPOSE To compare fully quantitative and semiquantitative analysis of rest and stress myocardial blood flow (MBF) and myocardial perfusion reserve (MPR) using a dual-bolus first-pass perfusion MRI method in humans. MATERIALS AND METHODS Rest and dipyridamole stress perfusion imaging was performed on 10 healthy humans by administering gadolinium contrast using a dual-bolus protocol. Ventricul...
متن کاملCerebral Perfusion Imaging with a Hyperpolarized Freely Diffusible Contrast Agent
Introduction: Hyperpolarized contrast agents have a number of attractive features for application to perfusion imaging [1]. Indeed, these agents provide high signal strength with virtually no endogenous background signal and therefore make excellent tracers for monitoring blood flow. In comparison to arterial spin labeling (ASL), which produces signal modulations on the order of a few percent, ...
متن کاملApplicable risk assessment methods in occupational and environmental exposure to nanoparticles - a narrative review
Nanoparticles (NPs) are a heterogeneous group of materials that have various applications, and their risk assessment is an essential condition. This study aimed to review the applicable risk assessment methods in occupational and environmental exposures to NPs. A literature search for articles published since 2005 in Web of Knowledge, Scopus, PubMed, Science Direct, and Google Scholar, using ap...
متن کاملHyperpolarized 13C MRI Cineangiography of Pulmonary Perfusion
Introduction: Accurate and repeatable measures of pulmonary perfusion play an important role in the study of many pulmonary pathophysiologic conditions. Unfortunately, radiation exposure precludes the use of many nuclear medicine and computed tomographic techniques in longitudinal studies. Additionally, current MRI measures of pulmonary perfusion are difficult to implement. Water-soluble HP C c...
متن کاملEstimation of absolute myocardial blood flow during first-pass MR perfusion imaging using a dual-bolus injection technique: comparison to single-bolus injection method.
PURPOSE To compare the dual-bolus to single-bolus quantitative first-pass magnetic resonance myocardial perfusion imaging for estimation of absolute myocardial blood flow (MBF). MATERIALS AND METHODS Dogs had local hyperemia of MBF in the left anterior descending (LAD) coronary artery (intracoronary adenosine). Animals (n = 6) had sequential single- and dual-bolus perfusion studies with micro...
