CT always better: CT is always better than ultrasound but for screening purposes the ultrasound causes no radiation effect. If multiple CTs were performed over time the RT could be significant. The ultrasound can tell whether a lesion is solid or cystic and whether the latter is simple or complex. The CT can show detail not seen on ultraound.

It would show up if: An ovarian cyst would show up on a ct scan as long as you had a scan of your abdomen and pelvis, and the cyst was large. Very small cysts would not be obvious on ct. Ultrasound is generally considered a better imaging modality for ovarian cysts, because it exposes the patient to less radiation and is a cheaper test.

Pelvic ultrasound in considered to be the standard imaging modality for female pelvic structures. Despite improvements in CT scanning technology, it is still an inferior test for this purpose.
