Peds/CHD Pre-Conference Course 01 - Introduction to Pediatric & CHD CMR-Discussion

Video Transcription

Video Summary

The Q&A covered fetal cardiac MRI methods, technical setup, and clinical considerations. Dr. Lloyd explained that current open-source, non-AI pipelines already provide useful anatomical imaging and retrospective gating from fetal heart motion, with future work focused on validation, motion correction, and resolution. The group discussed 1.5T vs 3T, with current experience favoring 1.5T, and described how balanced sequences estimate fetal heart rate for 4D reconstruction. Other topics included contrast use for 3D SSFP, pediatric reference values for ventricular volumes, and how anesthesia, oxygen, and blood pressure can affect flow measurements in shunt and pulmonary hypertension studies.
