Six real x-rays, CAT scan, MRI, and ultrasound images on transparent plastic overlays beg for an explanation —provided within an engaging read-aloud story that children will enjoy for its own sake. When Jessica breaks her arm, the reader follows her on a tour of the hospital and has a chance to examine the same images Jessica sees. A gentle, easy-to-understand introduction to medical care for all ages, it also includes a key so older children can learn to read each type of image. 28 pages.
