Diagnostic Imaging is a Key Tool in the Early Diagnosis and Prevention of Disease. Of high importance in today's managed care environment, diagnostic imaging can also be used for the early identification of potential medical problems, to help prevent their occurrence. Thus expensive therapeutic treatment may be eliminated to create substantial savings for the patient and healthcare system.
Vomiting is a vital reflex controlled by the medulla oblongata LES relaxes-allowing stomach contents to move into the esophagus Diaphragm and abdominal muscles contract-squeezing the stomach & forcing contents upwards. î î î. Esophagus enters the abdominal cavity through an opening in the diaphragm.This opening becomes enlarged, stomach is pushed up into the thoracic cavity. Additional pressure causes the LES to relax.

The esophagus transports food from the mouth to the stomach and prevents gastric or esophageal contents from moving backward into the mouth. It is a hollow tube, roughly 10 inches long; the length of the esophagus correlates with an individual's height.his lower esophageal sphincter, or LES, plays a critical role in GERD. The hollow walls of the esophagus are lined with a three-layer mucosa. The first layer is composed of soft, scalelike cells. Underneath is a supporting layer of connective tissue and then a thin layer of muscle fiber.
