| 20140070803 | MR Parallel Imaging System Reducing Imaging Time - An MR imaging system uses multiple RF coils, for reducing image acquisition time, suitable for chemical exchange saturation transfer (CEST) imaging. Multiple RF (Radio Frequency) coils provide CEST imaging preparation in an anatomical volume by providing multiple interleaved RF pulses. The multiple interleaved RF pulses provide substantially increased RF pulse sequence duty cycle in the multiple RF coils relative to a duty cycle provided by a single coil of the multiple RF coils. The multiple RF coils subsequently provide RF excitation pulses in a reduced anatomical volume using k-space undersampling in an accelerated imaging method using the multiple RF coils and enable subsequent acquisition of associated RF echo data for deriving a CEST image. | 03-13-2014 |

| 20150048821 | ATHEROSCLEROSIS CHARACTERIZATION USING A MULTI-CONTRAST MRI SEQUENCE - The present invention relates to imaging and characterizing atherosclerotic lesions. The invention utilizes a low-flip-angle gradient echo-based MRI acquisition technique combined with specialized magnetization preparative schemes (i.e. non-selective inversion and FSD), and multiple co-registered 3D image sets with different contrast weightings are collected in an interleaved fashion. Using the inventive method, a single scan allows for comprehensive assessment of atherosclerotic plaque within just a few minutes. | 02-19-2015 |
| 20150192653 | SYSTEMS AND METHODS FOR MYOCARDIAL PERFUSION MRI WITHOUT THE NEED FOR ECG GATING AND ADDITIONAL SYSTEMS AND METHODS FOR IMPROVED CARDIAC IMAGING - In some embodiments, the present application discloses systems and methods for cardiac MRI that allow for continuous un-interrupted acquisition without any ECG/cardiac gating or synchronization that achieves the required image contrast for imaging perfusion defects. The invention also teaches an accelerated image reconstruction technique that is tailored to the data acquisition scheme and minimizes or eliminates dark-rim image artifacts. The invention further enables concurrent imaging of perfusion and myocardial wall motion (cardiac function), which can eliminate the need for separate assessment of cardiac function (hence shortening exam time), and/or provide complementary diagnostic information in CAD patients. | 07-09-2015 |
| 20150217262 | DEVICES AND METHODS FOR PARAHYDROGEN INDUCED POLARIZATION - The present invention teaches devices and methods for hyperpolarization by parahydrogen induced polarization. The invention teaches several significant improvements over previous designs, including a heating block, an enhanced solenoid component, and pinch valves and tubing that provide a sterile environment for the sample. All of these advancements can be accomplished while keeping costs to produce the device relatively low. | 08-06-2015 |
| 20150323638 | NON-INVASIVE QUANTIFICATION OF CORONARY ARTERY FRACTIONAL FLOW RESERVE USING MRI - A system for quantifying a fractional flow reserve (FFR) in a mammalian subject comprises implementing a multi-dimensional phase-contrast magnetic resonance sequence using an MRI scanner to scan a volume of interest (VOI) in the mammalian subject. The VOI comprises at least a portion of the mammalian subject's heart, one or more blood vessels, or both. A pressure gradient within a blood vessel segment of interest within the VOI is determined based on the implemented multi-dimensional phase-contrast magnetic resonance sequence. The determined pressure gradient is correlated to an FFR value. | 11-12-2015 |
