纳入标准:

Inclusion criteria

排除标准:

1.既往有胰腺治疗史或上腹部大手术导致解剖结构显著改变者; 2.图像存在严重金属伪影或运动伪影,导致解剖结构不可辨认; 3.真实增强CT强化效果不佳,无法作为训练真值; 4.平扫与增强图像配准失败,无法构建成对训练数据。

Exclusion criteria:

1. Those who have a history of pancreatic treatment or major upper abdominal surgery that has significantly changed their anatomical structure; 2. Severe metal artifacts or motion artifacts in the image, resulting in unreadable anatomy; 3. The real enhancement CT reinforcement effect is not good and cannot be used as the training truth value; 4. The registration of the flat scan and enhanced images fails, and paired training data cannot be constructed.
