Blind Compressed Sensing-based Ultrafast Chemical Exchange Saturation Transfer (CEST) Imaging
CEST imaging, such as amide proton transfer (APT) imaging, is a novel, clinically valuable molecular MRI technique that can give contrast due to a change in water signal caused by chemical exchange with saturated solute protons. However, its clinical translation is still limited by its relatively long scan time because a series of RF saturation frequencies are unavoidably acquired. Here, we pre...
متن کاملBlind Compressed Sensing Dynamic MRI
Introduction: Achieving high spatio-temporal resolutions in dynamic MRI (DMRI) (eg. myocardial perfusion MRI) is often challenging due to the slow nature of MR acquisitions. Recently, several schemes that exploit the low-rank property of dynamic datasets were introduced to accelerate dynamic MRI [eg: 1-3]. These methods exploit the similarity of the voxel time profiles (intensity variations as ...
متن کاملResponsive paramagnetic chemical exchange saturation transfer MRI contrast agents
Molecular imaging research has shown great potential to assess the molecular compositions of tissues and provide critical information for clinical diagnoses [1]. These noninvasive assessments of molecular compositions may provide earlier diagnoses of pathologies, may predict therapeutic effects before the therapy is initiated and may provide earlier assessments of therapeutic effects soon after...
متن کاملAccelerating dynamic imaging of the lung using blind compressed sensing
Background Real time dynamic lung MRI is a promising tool to noninvasively assess lung function and mechanics. However, it potential is not realized in the clinic due to the restricted spatio-temporal resolution and volume coverage. The main focus of this work is to overcome these drawbacks using the recent blind compressed sensing (BCS) scheme [Lingala et al., IEEE TMI 2013], which enables rec...
متن کاملImaging Lung Cancer by Using Chemical Exchange Saturation Transfer MRI With Retrospective Respiration Gating
Performing chemical exchange saturation transfer (CEST) magnetic resonance imaging (MRI) in lung tissue is difficult because of motion artifacts. We, therefore, developed a CEST MRI acquisition and analysis method that performs retrospective respiration gating. Our method used an acquisition scheme with a short 200-millisecond saturation pulse that can accommodate the timing of the breathing cy...
