Motion is a common cause of image quality degradation in pediatric MRI and comes from a variety of sources. Motion artifacts can lead to difficulty visualizing small structures, incorrect apparent diffusion coefficient calculations on DWI, ghosting and blurring artifacts, and the need to repeat individual sequences or an entire exam. This talk will review current techniques to decrease patient motion, including fast imaging techniques, motion-robust sequences, indications for anesthesia/sedation, and motion correction technology. These strategies can all help reduce motion degradation and improve image quality during pediatric MRI.

Augmented reality (AR) and virtual reality (VR)  tools for radiology are starting to make a difference in real-world educational and clinical applications. This talk provides examples of real educational and clinical applications in the field of radiology with discussion of methods of implementation.

Placental relaxometry provides quantitative characterization of placental tissue. Placental dysfunction is associated with placental hypoxia, which can be depicted by placental relaxometry. Thus, this method provides direct evidence of placental dysfunction during pregnancy, which has the potential to improve pregnancy outcome through optimal pregnancy monitoring and timely delivery. This session will cover a comparison of placental T1, T2 and T2* in the prediction placental dysfunction, a correlation between MR images and placental anatomy, and a summary of current pitfalls of placental relaxometry in terms of acquisition, processing, and interpretation.

Placenta Accreta Spectrum Disorder (PASD) is a life-threatening condition occuring in female patients who have previously undergone cesarean section or uterine instrumentation. In this condition, the placenta is strongly adherent to or invades the myometrium, without intervening decidua. It does not separate normally at the time of delivery, leading to catastrophic hemorrhage. Identifying the most frequent signs of PASD helps with diagnosis, including T2-dark intraplacental bands, placental/uterine bulge, loss of retroplacental T2-hypointense line, myometrial thinning and bladder wall interruption and focal exophytic mass and abnormal vascularization of placental bed. Presence of placental bulge is suggestive of higher grades of myoinvasion.

Advances in in-vivo fetal magnetic resonance imaging (MRI) have driven a vastly improved analysis of prenatal brain development, in-utero. In this presentation, we review post-acquisition processing techniques for fetal MRI. Our journey begins with a review of motion-corrected super-resolution slice-to-volume reconstruction techniques that have been at the center of the advances in fetal MRI. We will then discuss the applications of these techniques, including the construction of normative, spatiotemporal MRI atlases of the fetal brain, and techniques for image segmentation and group analysis. This talk covers techniques for the analysis of T2-weighted, diffusion-weighted, and functional MRI of the fetal brain.
