Recently my wife purchased a thick and expensive book. As an ultrasonic diagnostician for children, she purchases many books, but this one had me puzzled. The book was titled Ultrasound Anatomy of the Healthy Child. Why would she need a book that showed only healthy children? I asked her and her answer was simple: to diagnose any disease, even one not yet discovered, you need to know what a healthy child looks like.
In this article we will act like doctors, analyzing and comparing a healthy and a not-so-healthy application.
Knock – knock – knock.
