Comparative StudyPregnancy outcomes after fallopian tube recanalization: oil-based versus water-soluble contrast agents.
To determine the pregnancy outcomes in patients undergoing fallopian tube recanalization (FTR) with use of oil-based versus water-soluble contrast agents. ⋯ The use of an oil-based agent had little effect on the rate of conception, but time to conception was reduced by more than 3 months.

Improvement of sonographic needle visibility in cirrhotic livers during transjugular intrahepatic portosystemic stent-shunt procedures with use of real-time compound imaging.
The visibility of a transjugular intrahepatic portosystemic stent-shunt (TIPS) puncture needle was assessed with use of real-time compound imaging and single-line ultrasonography (US). In vitro and in vivo, needle-tissue contrast was calculated. ⋯ Subjective evaluation during TIPS procedures in 10 patients proved that the needle tip was significantly better seen with compound imaging. Therefore, real-time compound imaging significantly improved contrast and subjective visibility of the needle.
