简要总结
To assess diagnostic performance of Dual Energy CT fo gallblader gallstone detection.
详细描述
Detection of gallbladder gallstone using Dual Energy CT compare to gallblader ultrasound (gold standard).
All patients who undergo dual-energy CT scans will undergo abdominal ultrasound for gallstones.
Performance of CT to conventionnal KeV will be compare to low Kev monoenergetic reconstruction, and Effective Z.
Expected duration of inclusion 3-6 months. No follow-up.
