Methods: Each one of forty-five cases(two stones for each one) were scanned by CT in vitro. Infrared spectrum was performed to analyse qualitatively the stones. The other one of them was dissolved by MTBE. Results: The stones may be divided into five patterns according to CT features. The cholesterol content correlated well with dissolution outcome; only the stones containing more than 40% cholesterol could be dissolved. The lower CT value of a homogeneous stones the faster dissolution of it, and the less residual mass, viceversa. The cholesterol content of the rim of a laminate stone may affect its dissolution course. The rim with less cholesterol content could be penetrated and the center with more cholesterol could be dissolved by MTBE. Conclusion: CT scans can predict the process and outcome of MTBE dissolution of a gallstone exactly.展开更多
