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.
