Looking to calculate the surface area of peritoneal cavity via MRI / CT

This would include the surface area of the peritoneal cavity (lining or peritoneum) itself and , if possible, the surface area of the organs inside the peritoneum. Ideally selectively by organ, also if possible. Has this been done? Thanks, Ric

If you segment the peritoneal cavity and each organ of interest then you can get the surface areas automatically using Segment Statistics module.
