In addition to the identification of intramural gas, what should be carefully sought radiographically, to aid in assessment of severity?
Intravascular gas (in the portal circulation) and intraperitoneal gas (indicating perforation).
What is the earliest sign of necrotising enterocolitis radiographically?
Bowel dilatation. Intramural gas is only evident as the severity increases.
