In brief: Better details

The resolution, details shown, on ct is more effective than that of ultrasound.
Ultrasound shows liquids e.g. Cysts and effusion better and is cheaper but in obese patients ultrasound has limited penetration. Accordingly, ultrasound, in these patients, is usually replaced by ct that views fatty tissues better and penetrates as deep as needed for better resolution.

In brief: Many things

There are many things in many organs that a ct will show but intestines are probably the biggest thing not evaluated at all on ultrasound.
