ABSTRACT
Objective To investigate the methods and clinical value of multi-slice CT virtual cholangioscopy in the detection of biliary calculus.Methods Volume scanning was performed in 38 patients with suspected biliary calculi after injection 50% Meglumine adipiodone injection 20 ml through vien.All data sets were transferred to ADV3.1 workstation.MSCTVC reconstruction were done with Navigator soft-ware.All cases were proved by ultrasound,axial CT and MSCT 3 D results or operations.Results MSCTVC could well demonstrate 3D fashion of biliary calculi and it was similar to ultrasound,axial CT and MSCT 3D results.Conclusion MSCTVC combined with CT 2D 3D results has a high diagnosis accuracy and clinical usefulness,thus,improve the diagnosis of biliary calculi.
