Musculoskeletal and fetal imaging; imaging of vascular anomalies including vascular neoplasms and vascular malformations

Arnold Carlson “Carl” Merrow Jr., MD, grew up in Alabama and received a Bachelor of Science in chemistry from Auburn University in 1997. After completing medical school and residency in Birmingham, AL, he spent two years in fellowship at Cincinnati Children’s Hospital Medical Center. While the first fellowship year was focused on general pediatric radiology, the second year was split between pediatric body/musculoskeletal MRI and pediatric neuroimaging. After spending the next two years in a pediatric radiology private practice, Dr. Merrow returned to Cincinnati Children's where he fostered new interests in fetal imaging, vascular anomalies and fellow education.

Since his return in 2010, Dr. Merrow has authored numerous book chapters and peer-reviewed publications and has helped to develop interactive web-based educational products in pediatric radiology. He has been selected from departmental faculty for the Corning Benton Outstanding Educator Award by each graduating class of pediatric radiology fellows from 2011 to 2013. Dr. Merrow was also selected for the first annual Faculty Educational Achievement Award from amongst all junior faculty of Cincinnati Children's in 2011.
