Quantitative three-dimensional myocardial perfusion cardiovascular magnetic resonance with accurate two-dimensional arterial input function assessment
BACKGROUND Quantification of myocardial perfusion from first-pass cardiovascular magnetic resonance (CMR) images at high contrast agent (CA) dose requires separate acquisition of blood pool and myocardial tissue enhancement. In this study, a dual-sequence approach interleaving 2D imaging of the arterial input function with high-resolution 3D imaging for myocardial perfusion assessment is presen...
متن کاملEvaluating the Effect of Injected Dose of 99mTc- MIBI on the Quantitative Parameters of Myocardial Perfusion Imaging
Background: 99mTc-MIBI cardiac perfusion scanning is recognized as a clinically useful method in evaluating coronary artery disease. By the implementation of new imaging techniques and systems, it seems possible to obtain high-quality images with a lower dose of radiopharmaceuticals. The purpose of this study was to evaluate the effect of injection dose of 99mTc-MIBI on quantitative parameters ...
متن کاملQuantitative myocardial perfusion imaging using a step arterial-input function
Background Modern MRI myocardial perfusion protocols use rapid venous bolus injections, typically 3-5 ml/s of 5-15 ml of agent over a few seconds. The resulting arterial input functions are rapidly varying with high agent concentrations (Fig. 1A and 1B) and thus typically require high temporal resolution acquisitions (~1 sec), custom pulse sequences and complex processing methods for perfusion ...
متن کاملAn Efficient Framework for Accurate Arterial Input Selection in DSC-MRI of Glioma Brain Tumors
Introduction: Automatic arterial input function (AIF) selection has an essential role in quantification of cerebral perfusion parameters. The purpose of this study is to develop an optimal automatic method for AIF determination in dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) of glioma brain tumors by using a new preprocessing method.Material and Methods: For this study, ...
متن کاملQualitative and quantitative myocardial perfusion with arterial spin labeling
Introduction A reduction of myocardial blood perfusion is the main physio-pathologic mechanism determining ischemic heart disease. Whilst SPECT and echocardiography are considered the reference standards for imaging perfusion defects, MRI techniques are emerging. Dynamic imaging of the first-pass of a contrast agent is currently the most frequently used of these techniques, however, guidelines ...
