After fellowship I moved to Beth Israel Deaconess Medical Center and Harvard Medical School in Boston. As attending staff in Boston, I initiated research on MRI as an adjunct to ultrasound in Obstetrics. Our laboratory introduced use of the ultrafast sequence (HASTE) for superb visualization of the fetus. This led to NIH-funded research to assess fast MRI of the abnormal fetal central nervous system. Over 80 manuscripts emanated from this work including articles on MR in placenta accreta, appendicitis in pregnancy, normal fetal anatomy, cortical development, and CNS anomalies. In addition, I maintain a website “Compendium of Fetal MRI” and wrote the book “Atlas of Fetal MRI.” Work from my laboratory dramatically changed the manner in which obstetric patients are counseled and managed. Using MR we are able to provide triage for patients with clinical suspicion of appendicitis without the need for ionizing radiation, decreasing the need for CT in pregnancy. Using MR we have improved our ability to counsel patients with fetal anomalies, particularly in the CNS. Opportunities for research and collaboration come in many forms. In April 2016 I attended the JPR conference in Sao Paolo that was jointly sponsored by RSNA. While at the conference I spoke to a group of research studying the effect of Zika virus on pregnancy. Given my history of research in ultrasound and MR of fetal brain abnormalities, they asked for my help in evaluating and categorizing the abnormalities that they had imaged. The collaboration with this group led to our 2016 publication in Radiology, that made over 100 images available for health care providers around the world, to aid in better understanding of the disease.
