Normalized gradient fields for nonlinear motion correction of DCE-MRI time series
Dynamic MR image recordings (DCE-MRI) of moving organs using bolus injections create two different types of dynamics in the images: (i) spatial motion artifacts due to patient movements, breathing and physiological pulsations that we want to counteract and (ii) signal intensity changes during contrast agent wash-in and wash-out that we want to preserve. Proper image registration is needed to co...
متن کاملMotion correction of contrast-enhanced MRI time series of kidney
In this paper we focus on motion correction of contrast enhanced kidney MRI time series, which is an important step towards accurate assessment of regional renal function. Due to respiratory motion and pulsations, the organ of interest undergoes complex movement and deformation, which disturb further renal function analysis. We propose geometric movement correction by image registration. We hav...
متن کاملRespiratory motion correction in dynamic MRI using robust data decomposition registration - Application to DCE-MRI
Motion correction in Dynamic Contrast Enhanced (DCE-) MRI is challenging because rapid intensity changes can compromise common (intensity based) registration algorithms. In this study we introduce a novel registration technique based on robust principal component analysis (RPCA) to decompose a given time-series into a low rank and a sparse component. This allows robust separation of motion comp...
متن کاملMethodology for Robust Motion Correction of Complex-valued MRI Time Series
Introduction: In functional MRI (fMRI), the presence of subject motion during the acquisition of an image series can confound results. In general practice, only the magnitude portion of the images is used in the functional analysis [1], and thus correction for subject motion is required in only the magnitude images. However, statistical models for performing complex-valued fMRI analysis are ava...
متن کاملMotion Corruption Detection in Breast DCE-MRI
Motion corruption can result in difficulty identifying lesions, and incorrect diagnoses by radiologists in cases of breast cancer screening using DCE-MRI. Although registration techniques can be used to correct for motion artifacts, their use has a computational cost and, in some cases can lead to a reduction in diagnostic quality rather than the desired improvement. In a clinical system it wou...
