Dr. Jeff Goldstein, MD, PhD won the best clinical poster award at Pathology Visions 2020. His poster "AI estimation of gestational age based on microscopic appearance of placental villi" describes a model for predicting gestational age from whole-slide images of placenta histology. Abnormal maturation rates of the placenta are indicators of a variety of possible conditions, and a computational system can help to overcome the considerable subjectivity of manually calling gestational age currently done by pathologists. This work was supported by Dr. Goldstein's NIBIB K08 Clinical Investigator Award.
