MRI Radio-frequency Heating Amelioration for Metallic Braided Catheters

Unmet NeedOver 1,000,000 cardiac catheterizations are performed annually in the United States. Catheters with a braided surface are most commonly used in vascular intervention because of their superior mechanical properties. While braided catheters made of metal provide the best mechanical manipulation, metallic catheters longer than a quarter of the...

Novel CEST MRI-suitable Reporter Genes to Non-Invasively Monitor Distribution and Migration of Biotherapeutics

Unmet NeedGreen Fluorescent Protein (GFP) reporter genes and PET (positron-emission tomography) imagining are two techniques which have been widely used to monitor the movement and distribution of specific molecules in cells or animals. Imaging GFP-tagged molecules is often destructive to the sample and is limited by the degree that light can penetrate...

Method of Spatially-encoded NMR Parameters from Arbitrarily-shaped Compartments an Linear Algebraic Modeling

SLAM is a new method to accelerate the acquisition of NMR and MRI measurements that are spatially localized to arbitrarily shaped compartments, many-fold. If compartment-average indices can suffice, SLAM can speed-up clinical or animal studies by up to scores-fold, and generate quantitatively equivalent results to compartment average measures obtain...

Salicylic Acid-based Polymeric CEST Contrast Agents for Molecular Imaging of Prostate-specific Membrane Antigen

We have discovered that a salicylic acid (SA) analog when grafted on a polymeric platform is able to produce significantly enhanced contrast in MR images detectable through chemical exchange saturation transfer (CEST). That SA modified polymeric platform (SA PolyCEST), has been further modified with Glu-Lysine urea, an inhibitor of Prostate-specific...

A comprehensive post-processing toolbox for magnetic resonance based peripheral vascular imaging

Peripheral artery disease (PAD) is an important public health concern particularly among the elderly. Although measures such as ankle-brachial index and segmental pressures have been used to characterize disease severity, new magnetic resonance based imaging techniques allow us to assess subclinical vascular function and morphology. Here, we describe...

System and Method For Blood Brain Permeability Imaging (BBPI) Using Dynamic Susceptibility Contrast Magnetic Resonance Imaging

Description:The blood-brain barrier (BBB) plays a critical role in both normal function and pathological states of the brain. While disruption of the BBB can be a hallmark of disease activity, the BBB also serves as a barrier to drug delivery. Thus, imaging the BBB has innumerable applications. Previous attempts to image the BBB have not been sensitive...

Improved Fitting Calculation For Diffusion Tensor Imaging

Diffusion tensor imaging is a new MRI modality that is becoming an important technique to assess various types of brain diseases. However, this technique has one weakness; its extreme sensitivity to patient motions. The image is often corrupted by patient motions as small as cardiac pulsation of the brain. Even though this problem is ameliorated by...
