Overview
Abdominal CT scan may be helpful in the diagnosis of ascites. Findings on CT scan suggestive of ascites include fluid accumulation within abdominal cavity, defined as transudate (same density as water), exudate (more density than water), and hemoperitoneum (density as ~45 HU).
CT Scan
Abdominal CT scan may be helpful in the diagnosis of ascites. Findings on CT scan suggestive of ascites include:[1]
- Fluid accumulation within abdominal cavity.
- Same density as water (-10 to +10 HU): Transudate
- More density than water (>15 HU): Exudate
- Density as ~45 HU: Blood (hemoperitoneum)
