1.) Congratulations to FNNDSC'S Dr. Jeffrey N Stout and collaborators for being awarded magna cum laude on the presentation titled "Placental MRI: Using a novel ex vivo placental perfusion chamber to validate in vivo MRF relaxometry" during the ISMRM & SMRT Virtual Conference this week!
Watch the full talk here:
The placenta is a challenging MRI target. Acquisition schemes developed for other organs, with implicit assumptions about motion, tissue composition and perfusion, should be vetted for applicability to the placenta. We have developed an ex vivo placental perfusion chamber with integrated MRI receive coil for high SNR and imaging acceleration to validate in vivo acquisitions in a controlled environment. Here we examine the effect of flowing spins on MRF relaxometry. We offer evidence that T1 is sensitive to overall fluid volume, while T2 is additionally sensitive to spin inflow. Our ex vivo placental perfusion system appears promising for validating in vivo quantitative MRI.
