Synopsis
Keywords: Cardiovascular: Cardiac, Cardiovascular: Blood, Image acquisition: Motion correction
In this
presentation, I summarize recent advances in fetal cardiovascular MRI and discuss
potential directions for the field. A wide range of topics will be introduced
including dynamic cardiac imaging, flow quantification, and blood oximetry. The
techniques that support such work will also be discussed including fast
imaging, motion compensation, novel gating strategies, and volumetric
reconstruction.

Fetal
cardiovascular MRI has evolved significantly over the last 15 years. It is now
an important research tool for the assessment of cardiovascular anatomy and physiology,
with growing interest in its clinical application. Some examples of its capabilities
are:
- Detection
of congenital heart defects, information on their severity and location, and identification
of associated abnormalities such as lung involvement, which can affect
postnatal management.
- Assessment
of cardiac function through measurement of myocardial wall motion, strain, and cardiac
output.
- Quantification
of disrupted blood flow distribution in the presence of congenital heart
disease, including volumetric blood flow quantification (4D flow).
- Assessment
of blood oxygen saturation and hematocrit which, together with blood flow,
provide oxygen delivery and consumption.
- Promise
of improved surgical planning and monitoring of fetal response to in utero treatment.
These
capabilities demand ongoing technical development in fast imaging, motion
correction, and image reconstruction, as well as advances in MRI hardware to
support such applications. In this presentation, I discuss recent innovations
in fetal cardiovascular MRI and potential directions for the field.
