简要总结
This is a prospective, non-randomized study of 50 people with suspected biliary dyskinesia. The purpose of this study is to investigate if it is possible to use ultrasound to make a diagnosis of a condition called biliary dyskinesia. The investigators null hypothesis is that there will be no statistical difference between the proposed experimental test (Ultrasound) and the HIDA scan (a nuclear medicine hepatobiliary system scan) in the diagnosis of biliary dyskinesia.
