Answer

The diagnostic yield of plain radiography is relatively low. Nevertheless, the diagnosis of NEC can be facilitated by obtaining a plain film radiograph of the abdomen, demonstrating pneumatosis intestinalis (ie, gas accumulation in the submucosa of the bowel wall) in 50-75% of patients, gas in the portal vein in severe cases, and pneumoperitoneum in patients with perforation of the bowel.

Plain film radiography can also be useful in establishing a diagnosis of toxic megacolon, bowel obstruction, or perforation; consequently, it should be performed as an initial study.
