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.


Inclusion Criteria: 1. All subjects will have a suspected clinical diagnosis of biliary dyskinesia, including an ultrasound that demonstrates biliary wall thickness of < 3 mm, and no gallstones present. 2. Written informed consent document. 3. Males and Females age > 18 years Exclusion Criteria: 1. Subjects without a suspected clinical diagnosis of biliary dyskinesia, including an ultrasound that demonstrates biliary wall thickness of > 3 mm, and/or gallstones present. 2. Pregnant or breastfeeding women 3. Subjects who do not consent to take part in the study.

Study Outcomes

Outcome Type:Primary Outcome
Measure:Does ultrasound test detect contraction of gallbladder following injection of a hormone cholecystokinin (CCK), and is the degree contraction as accurate as the accepted clinical standard (the HIDA scan) for diagnosis of biliary dyskinesia.
Time Frame:After HIDA scan performed
Safety Issues:False

Study Interventions

Intervention Type:Procedure
Name:CCK Injection and Ultrasound
Description:All subjects, whether they participate in this study or not, will undergo the HIDA scan as this is the accepted standard of care for diagnosing biliary dyskinesia. If a given subject agrees to participate in this study, he/she will be asked to undergo the following study procedures: If a pregnancy test has not already been done, a urine pregnancy test will be done for women of childbearing potential. An intravenous line (IV) will be inserted (if not already in place), and a standard dose of CC
