Cardiac BOLD Imaging with Cine 2D-Balanced SSFP
Introduction Detecting changes in oxygen content in tissues can aid in understanding pathological processes. In the MR environment, changes in blood oxygen saturation are accompanied by local magnetic field variations sampled by the spins, allowing for acquisition of oxygen-weighted images [1-2]. This observation has been exploited in identifying myocardial oxygen deficits that originate from c...
متن کاملQuantitative magnetization transfer imaging using balanced SSFP.
It is generally accepted that signal formation in balanced steady-state free precession (bSSFP) is a simple function of relaxation times and flip angle only. This can be confirmed for fluids, but for more complex substances, magnetization transfer (MT) can lead to a considerable loss of steady-state signal. Thus, especially in tissues, the analytical description of bSSFP requires a revision to ...
متن کاملRoutine 3D SSFP cine imaging for improved analysis of myocardial volumetry and deformation
Background Conventional 2 dimensional (2D) cine MRI of myocardial motion is limited in its ability to describe the complex 3 dimensional (3D) motion of the heart due to sparse coverage and inconsistent breath-holding. So far, clinical feasibility of 3D cine imaging has been limited due to the long acquisition times and requirements for acceleration techniques that are not routinely available. W...
متن کاملTransient Balanced SSFP Imaging with Increased Signal by Variable Flip Angles
INTRODUCTION: Often in balanced steady state free precession (bSSFP) acquisitions, physiological motion or use of contrast preparation mechanisms limit the acquisition block length. Therefore, acquisition occurs intermittently and during the transient (as opposed to steady state). This work presents a method for calculating variable flip angles for bSSFP acquisition to generate echoes at predef...
متن کاملCMR imaging of edema in myocardial infarction using cine balanced steady-state free precession.
OBJECTIVES The aim of this study was to investigate the capabilities of balanced steady-state free precession (bSSFP) cardiac magnetic resonance imaging as a novel cine imaging approach for characterizing myocardial edema in animals and patients after reperfused myocardial infarction. BACKGROUND Current cardiac magnetic resonance methods require 2 separate scans for assessment of myocardial e...
