Sodium imaging of the heart at 7T: design, evaluation and application of a four-channel transmit/receive surface coil array
نویسندگان
چکیده
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-MRI makes 23Na-MRI unattractive for clinical use. With a high SNR and fast imaging technologies ultrahigh field MRI brings 23Na-MRI back into focus, asking for dedicated radiofrequency (RF) technology.

Design, evaluation and application of a modular 32 channel transmit/receive surface coil array for cardiac MRI at 7T
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-chan...

INTRODUCTION At 7T, transmit coil arrays using parallel transmit (pTx) [1] systems enable techniques to substantially improve B1 transmit fields. Receive coil arrays offer enhanced sensitivity and parallel imaging performance. However, significant challenges in ultra high field systems are still remaining for the design and implementation of RFcoils for dedicated transmit channels and their int...

متن کاملUsing a whole-body 31P birdcage transmit coil and 16-element receive array for human cardiac metabolic imaging at 7T
PURPOSE Cardiac phosphorus magnetic resonance spectroscopy (31P-MRS) provides unique insight into the mechanisms of heart failure. Yet, clinical applications have been hindered by the restricted sensitivity of the surface radiofrequency-coils normally used. These permit the analysis of spectra only from the interventricular septum, or large volumes of myocardium, which may not be meaningful in ...
متن کاملAssessment 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...
