Detailed Description

In this study, the investigator intend to collect abdominal CT from patients who are proposed to undergo bariatric surgery, to extract the radiomics of intra-abdominal fat and subcutaneous fat, and to establish a prediction model for predicting the efficacy of weight loss and remission of type 2 diabetes mellitus at 1 year, 3 years, and 5 years postoperatively, in conjunction with the clinical data.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Area under curve (AUC) of the weight loss prediction model after 1 year
Time Frame: 1 year
This metric shows the discriminatory ability of the radiomic model to predict the probability of inadequate weight loss after 1 year.
1 year
Area under curve (AUC) of the T2DM remission prediction model after 1 year
Time Frame: 1 year
This metric shows the discriminatory ability of the radiomic model to predict the probability of remission of T2DM after 1 year.
1 year

Secondary Outcome Measures

Outcome Measure
