“…On the one hand, MRI is minimally hampered by maternal or fetal factors such as obesity or challenging fetal positions. While it provides excellent visualization of both the fetal anatomy and its tissue characteristics, present MR temporal resolutions preclude it as a modality for comprehensive real‐time imaging and it does not lend itself to evaluation of blood flow as easily as Doppler technology. On the other hand, US is easily performed, is safe, and provides real‐time B‐mode and Doppler imaging with excellent temporal and spatial resolution.…”

Fusion imaging (FI), the simultaneous display of the same anatomical region using two imaging modalities, has been used in other areas of medicine for both diagnosis and guiding interventions. Examples include positron emission tomography‐computed tomography (PET‐CT) imaging in oncology and ultrasound‐magnetic resonance imaging (US‐MRI) fusion in biopsies of the prostate gland. The underlying principle is to take advantage of the complementary information in each modality to improve accuracy, be it diagnostic accuracy or targeting accuracy in biopsies. For example, PET‐CT overlays the metabolic activity of lesions on the superb spatial and anatomical detail of CT. While the historical mainstay of fetal imaging has been ultrasound, advances in ultrafast MR imaging together with advances in fetal MRI over the past two decades, have resulted in the opportunity to explore fusion imaging in fetal medicine. We present an overview of the principles of US‐MRI fusion imaging in prenatal medicine, report our local experience, and review the literature in this emerging area. We share our perspective on how FI can improve diagnostic confidence, be used as an educational tool, and potentially enhance guidance in certain fetal procedures.
