Patent number: 11774536Abstract: The ratio of arterial spin labeled (ASL) perfusion to diffusion weighted imaging (DWI) is generally homogeneous in the anoxic/hypoxic injury population. Conversely, the ratio is more heterogeneous in the non-anoxic/hypoxic population. By plotting these ratios in a graphical format in the form of an axial color map of the brain—referred to as a normalized diffusion to perfusion (NDP) ratio colormap—it may be determined whether a patient has suffered from an anoxic/hypoxic injury. Thus, the anoxic and non-anoxic injury patients will have, respectively, homogenous and heterogeneous color maps. Anoxic brain injury patients have a global homogeneously positive relationship between qualitative ASL perfusion and diffusion weighted signal such that areas of restricted diffusion show significantly increased ASL perfusion signal, which may be attributable to BBB integrity.Type: GrantFiled: February 11, 2021Date of Patent: October 3, 2023Assignee: Oregon Health & Science UniversityInventors: Jeffrey Michael Pollock, Ningcheng Li

Patent number: 11719778Abstract: Methods and systems generate synthetic late gadolinium enhancement (LGE) magnetic resonance images using a magnetic resonance fingerprinting (MRF) acquisition. From a single acquisition, MRF image data is obtained, including co-registered T1 and T2 tissue property maps. Different tissue regions of interest are identified, such as viable myocardium, scar, and blood and T1 and T2 values for each are determined. Based on these, different sets of pulse sequence parameters are determined, e.g., using different synthetic image contrast models receiving the MRF image data. Synthetic LGE images at different contrasts are generated as a result, including a synthetic bright-blood LGE image, a synthetic dark-blood/gray-blood LGE image, and a synthetic optimized imaged.Type: GrantFiled: January 31, 2022Date of Patent: August 8, 2023Assignees: REGENTS OF THE UNIVERSITY OF MICHIGAN, CASE WESTERN RESERVE UNIVERSITY, UNIVERSITY HOSPITALS CLEVELAND MEDICAL CENTERInventors: Jesse Hamilton, Imran Rashid, Nicole Seiberlich, Sanjay Rajagopalan
