Correction strategy for infants’ diffusion-weighted images corrupted with motion

Introduction In the developing brain, non-invasive Diffusion Tensor Imaging (DTI) and High Angular Resolution Diffusion Imaging (HARDI) provide crucial information on the early organization of white matter bundles [1,2] and monitor the progressive maturation and myelination of functional networks [3,4]. However these techniques are difficult to implement in non-sedated babies because of motion ...

Prospective Motion Correction for T2- and Diffusion-Weighted Breast Imaging with FADE

Introduction T2and diffusion-weighted imaging are useful as non-contrast-enhanced MRI techniques; however both are limited by low-resolution and blurring [1,2]. The Fast Acquisition Double Echo (FADE) sequence is a 3D steady-state sequence with two echoes per TR; spoiler gradients that separate the echoes provide diffusion weighting. FADE enables high-resolution T2and diffusion-weighting imagin...

Real-time optical motion correction for diffusion tensor imaging.

Head motion is a fundamental problem in brain MRI. The problem is further compounded in diffusion tensor imaging because of long acquisition times, and the sensitivity of the tensor computation to even small misregistration. To combat motion artifacts in diffusion tensor imaging, a novel real-time prospective motion correction method was introduced using an in-bore monovision system. The system...

Signal Intensity of High B-value Diffusion-weighted Imaging for the Detection of Prostate Cancer

Background: Diffusion-weighted imaging (DWI) is a main component of multiparametric MRI for prostate cancer detection. Recently, high b value DWI has gained more attention because of its capability for tumor characterization. Objective: To assess based on histopathological findings of transrectal ultrasound (TRUS)-guided prostate biopsy as a reference, an...

Motion correction of diffusion-weighted imaging of the liver: use of velocity-compensated diffusion gradients combined with tetrahedral gradients

Introduction: Diffusion-weighted magnetic-resonance imaging (DWI) with an apparent diffusion coefficient (ADC) is a useful MRI technique for the detection and characterization of liver lesions. A conventional pulse sequence for DWI adds bipolar gradients in three orthogonal directions, after excitation and before readout. These pulsed gradients will induce a phase shift due to cardiac motion as...
