Looking Within by Cullen Ruff, MD, is an exploration of our humanity through stories of medical imaging, highlighting the wonder and mystery of the human body, by literally and metaphorically looking inside of others.  Each chapter describes a patient in whom a life-changing discovery is made on an imaging study, including cancer, trauma, stroke, child abuse, pregnancy, sterility, substance abuse, secrets from a patient's past, surgical complications, paralysis, eating disorders, drug smuggling, even impending death. These true accounts give readers an increased appreciation for the intricacies of the human form, the complexity of existence, and the strength and vulnerability of our bodies. In the process, we gain insight about what it means to be human, in body and spirit.
