  • Systems, compositions and devices for magnetic resonance imaging of lungs using perfluorinated gas mixtures
    Patent number: 11653854
    Abstract: Systems and methods for generating MRI images of the lungs and/or airways of a subject using a medical grade gas mixture comprises between about 20-79% inert perfluorinated gas and oxygen gas. The images are generated using acquired 19F magnetic resonance image (MRI) signal data associated with the perfluorinated gas and oxygen mixture.
    Type: Grant
    Filed: October 29, 2020
    Date of Patent: May 23, 2023
    Assignee: Duke University

  • Magnetic resonance thermometry in the presence of water and fat
    Patent number: 8478380
    Abstract: The in vivo measurement of tissue temperature is performed during a medical procedure using an MRI system. Fat and Water images are acquired at each temperature measurement time and corresponding phase images are produced. A temperature map is produced by subtracting the phase at each Fat image pixel from the corresponding pixel in the Water phase image to improve measurement accuracy in tissues with fat/water mixtures.
