Volumetric Parameterization of the Placenta to a Flattened Template [PDF]

arXiv, 2021
We present a volumetric mesh-based algorithm for parameterizing the placenta to a flattened template to enable effective visualization of local anatomy and function. MRI shows potential as a research tool as it provides signals directly related to placental function.

Combined Diffusion-Relaxometry MRI to Identify Dysfunction in the Human Placenta [PDF]

Magn Reson Med. 2019;1-12, 2018
Purpose: A combined diffusion-relaxometry MR acquisition and analysis pipeline for in-vivo human placenta, which allows for exploration of coupling between T2* and apparent diffusion coefficient (ADC) measurements in a sub 10 minute scan time. Methods: We present a novel acquisition combining a diffusion prepared spin-echo with subsequent gradient ...
