纳入标准: |
1.年龄>=18岁; 2.胰腺肿瘤组:经病理证实为胰腺肿瘤(PDAC或其他肿瘤); 3.正常对照组:初始影像报告为胰腺正常,且回顾性收集 2015-2025 期间>=6 个月影像学随访(CT 或 MRI)无胰腺病变进展; 4.拥有完整的同一次检查的平扫、动脉期及门脉期增强CT数据; 5.层厚≤5mm,且扫描范围完整覆盖胰腺及周围关键血管; 6.针对可切除性评估子集:必须拥有详尽的手术记录及术后病理报告。 |
||||||||||||||||||||||
|
Inclusion criteria |
1. Age >= 18 years; 2. Pancreatic tumour group: pathologically confirmed pancreatic tumour (PDAC or other tumour); 3. normal control group: initial imaging reported as normal pancreas and no progression of pancreatic lesions on >=6 months imaging follow-up (CT or MRI) during the retrospective collection 2015-2025; 4. have complete plain, arterial phase and portal phase enhanced CT data from the same examination; 5. Layer thickness of ≤5mm and complete coverage of the pancreas and surrounding key vessels; 6. For the subset of resectability assessment: detailed surgical records and postoperative pathology reports must be available. |
||||||||||||||||||||||
|
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. |
