Overview
MR imaging of the neonatal chest and abdomen presents technical and logistical challenges. This session looks at the challenges of MR imaging of moving organs within the neonate and how to optimize image acquisition. It also presents the clinical utility of MRI when applied to the neonatal chest and abdomen.

Target Audience
Radiologists and scientists with an interest in the imaging of the neonatal chest and abdomen.

Educational Objectives
As a result of attending this course, participants should be able to:
- Explain the technical challenges of imaging the neonatal chest and abdomen, as well as strategies for overcoming them;
- Describe how to use MRI to image neonatal diseases of the chest and abdomen; and
- Identify which neonatal diseases are well characterized using MRI.

08:15		Optimization of MR Imaging of the Neonatal Body View Presentation Video Govind Chavhan Keywords: Cross-organ: Neonatal, Image acquisition: Motion Correction, Cross-organ: Pediatric It is important to maintain their vitals like body temperature, heart rate, blood pressure and oxygen saturation during the transportation and in the MRI scanner. Usually, light sedation from midazolam works well for NICU babies while feed-and-swaddle technique works well for non-NICU babies. Protocol should balance quality of imaging and time with most important sequences performed earlier, in case the baby wakes up. Most currently available sequences can be optimized to obtain diagnostic quality MR exam in neonates. There is limited data on use of gadolinium-based contrast media in neonates but are in general considered safe for use in neonates.
08:45		MR Imaging of the Neonatal Heart View Presentation Video Mehdi Hedjazi Moghari Keywords: Cardiovascular: Cardiovascular, Cardiovascular: Cardiac, Cardiovascular: Cardiac Pediatric cardiovascular magnetic resonance (CMR) imaging poses significant challenges due to bulk, respiratory, and cardiac motion. In this lecture, key concepts in motion correction will be covered, including electrocardiogram (ECG) gating, cardiac self-gating, respiratory navigators, respiratory self-gating, and state-of-the-art comprehensive free-breathing 3-dimensional (3D) CMR imaging.
