چکیده

Background Cardiac MR (CMR) at ultrahigh fields (≥7.0 T) is challenged by B1+ inhomogeneities and signal voids which bear the potential to spoil the signal-to-noise (SNR) benefits at 7.0 T. There is a trend towards an ever larger number of transmit and receive channels, to support multidimensional B1+ shimming and parallel imaging. Therefore this work proposes a modular, two dimensional 32-channel transmit and receive array using loop elements and examines its efficacy for enhanced B1+ homogeneity and improved parallel imaging performance.

Sodium imaging of the heart at 7T: design, evaluation and application of a four-channel transmit/receive surface coil array

Background Insight of physiological processes and cellular metabolism makes 23Na-MRI conceptually appealing as non-invasive imaging discipline. Several studies report the applicability of 23Na-MRI for the detection and assessment of acute and chronic heart disease due to increased sodium concentration after myocardial infarctions. Bi-exponential decay of the signal and a low SNR compared to 1H-...

Assessment of the Characteristics of MRI Coils in Terms of RF Non-Homogeneity Using Routine Spin Echo Sequences

Introduction: One of the major causes of image non-uniformity in MRI is due to the existence of  non-homogeneity in RF receive and transmit. This can be the most effective source of error in  quantitative  studies  in  MRI  imaging.  Part  of  this  non-homogeneity  demonstrates  the  characteristics of RF coil and part of it is due to the interaction of RF field with the material being  imaged...

7T Human in vivo Cardiac Imaging with an 8-Channel Transmit/Receive Array

Introduction: There are numerous reasons why cardiac MRI at high field strengths is a potentially challenging endeavor: the heart is subject to cardiac and breathing motion, necessitating peripheral pulse or preferably ECG-triggered sequences with breath holds or navigator sequences to capture the beating heart. Moreover, MRI signal generation is difficult due to inhomogeneous RF signal transmi...
