RESUMEN
Objective To investigate the value of post processing technique of MSCT in the diagnosis of bile duct stones.Methods 89 cases with high density bile stones were collected.All of the images were reconstructed by using surface reconstruction(CPR),multiplanar reconstruction(MPR),volume reconstruction(VR), to clearly show the location, size, number and shape of bile duct stones, and provide accurate image information for clinic.Results 396 cases of bile duct stones were detected in all of the 89 patients,after treatment,the reconstructed image of could accurately show the location,size,number and shape of stones.Conclusion Post-processing technique of MSCT can provide accurate image information for the diagnosis of the the biliary stone,and improve the effectiveness and safety of the operation.
