Rapid head‐pose detection for automated slice prescription of fetal‐brain MRI

Malte Hoffmann, Esra Abaci Turk, Borjan Gagoski, Leah Morgan, Paul Wighton, Matthew Dylan Tisdall, Martin Reuter, Elfar Adalsteinsson, Patricia Ellen Grant, Lawrence L. Wald, André J. W. Kouwe
2021 International journal of imaging systems and technology (Print)  
In fetal-brain MRI, head-pose changes between prescription and acquisition present a challenge to obtaining the standard sagittal, coronal and axial views essential to clinical assessment.  ...  To address this inefficient workflow, we propose a robust head-pose detection algorithm using full-uterus scout scans (EPI) which take ~5 seconds to acquire.  ...  The authors thank Cindy Zhou and Elizabeth Holland for identifying relevant clinical data and coordinating scan sessions, and Hanna Loetz for support and encouragement.  ...

2010 Magnetic Resonance in Medicine  
Phase-contrast magnetic resonance imaging (PC-MRI) can provide a complement to echocardiography for the evaluation of the fetal heart.  ...  In this thesis, I present a technique for reconstructing time-resolved fetal phase-contrast MRI in spite of this limitation.  ...  The presence of fetal movement between the acquisition of localizers and the PC-MRI series often results in incorrect slice prescriptions.  ...
