In Vivo Human Brain Diffusion Tensor Imaging (DTI) at 3T and 7 T

چکیده
Introduction: Higher B0 fields are expected to optimize fiber tracking and to increase the signal-to-noise ratio which should lead to higher spatial resolution of DTI [1,2]. However, at high fields B1 inhomogeneities are strong and result in sever distortions and signal voids in DTI. The B1 inhomogeneity results in ill-defined pulse angles that vary considerably over the probe volume. Parallel imaging enables DTI with reduced distortions and high spatial resolution [3-5]. We applied parallel imaging combined with data post-processing to acquire high resolution in vivo DTI at 3T and 7T.

Single-shot echo-planar imaging is the most common acquisition technique for whole-brain diffusion tensor imaging (DTI) studies in vivo. Higher field MRI systems are readily available and advantageous for acquiring DTI due to increased signal. One of the practical issues for DTI with single-shot echo-planar imaging at high-field is incomplete fat suppression resulting in a chemically shifted fa...
متن کاملHigh Resolution Diffusion Tensor Imaging of the Human Brain at 7T
Magnetic resonance imaging (MRI) at 7T provides higher signal-to-noise ratio (SNR) which enables high-resolution functional and anatomic MRI. There is also an increased demand for high-resolution diffusion tensor imaging (DTI) providing important information about cell physiology and neuronal connectivity. DTI may also profit from higher SNR as diffusion-weighting reduces the signal exponential...
متن کاملDiffusion Tensor Imaging at 7T: Expectations vs. Reality Check
INTRODUCTION Diffusion tensor imaging (DTI or HARDI) offers the unique possibility to detect brain microstructure in vivo. However, diffusion weighting requires strong and long gradient pulses that, in addition to strong T2 weighting, reduce the signal significantly to encode the directional information. Therefore, DTI is notoriously SNR hungry and the use of very high field strength has been p...
