Abdomen topography
Can the peritoneum be seen in radiological techniques?
It is very difficult to be seen, just when there is pathology it can be seen.

Peritoneum, retroperitoneum
The thicker the mesentery, the better it will be seen (T/F)
True, as it is mainly formed by fat. (Loops are seen better)
