John Caffey, a giant in the field of pediatric radiology, and author of the definitive text, Pediatric Radiologic Diagnosis, wrote in the foreword to the first edition, “He who would comprehend Röntgen's pallid shades, needs always to know well the solid matrix whence they spring. The physician needs to know intimately each living patient through whom the black light darts and flashing the hidden depth reveals them in a glowing mirage of thin images, each cast delicately in its own halo, but all veiled and blended endlessly.”

Advances in medical imaging have proceeded at a frenetic pace. It is vital for trainees to understand how best to use the various imaging modalities, as well as to learn how to interpret them. Kirpalani, Epelman, and Mernagh have done a superb job in assembling a balanced group of contributors to present the modern radiologic approach to the fetus and newborn infant so that trainees can meet these goals. They have managed to emphasize the evidence-based approach to problems and have highlighted the benefits versus costs and potential harm from various studies. The editors note that, “The clinical and radiological examinations are the foundation of medical investigation of the acutely ill neonate. The proper use and interpretation of radiological studies requires teamwork and clear communication between the clinicians (including the obstetricians and surgeons, as appropriate) and the radiologists.” Too true.
