研究目的:

构建并验证一个面向胰腺多病种(包括胰腺癌、急/慢性胰腺炎、胰腺囊性疾病等)的专用CT影像基础模型(Pancreas-ViT),并系统评估该模型在多个下游诊断任务中的性能与临床效用。  

Objectives of Study:

Construct and validate a dedicated CT imaging foundation model (Pancreas-ViT) for multiple pancreatic diseases (including pancreatic cancer, acute/chronic pancreatitis, pancreatic cystic diseases, etc.), and systematically evaluate the model's performance and clinical utility across multiple downstream diagnostic tasks.

纳入标准:

Inclusion criteria

排除标准:

1.CT图像存在严重伪影、运动模糊或扫描范围不全,影响胰腺评估。 2.曾接受过胰腺部分或全部切除手术。 3.伴有广泛腹腔转移、大量腹水或严重肠气干扰等影响胰腺观察的腹部疾病。 4.处于妊娠或哺乳期。 5.因精神障碍、认知功能受损等原因无法配合完成研究流程。 6.目前正在参与其他可能干扰本研究的临床试验。 7.存在碘对比剂过敏、未控制的甲状腺功能亢进等增强CT扫描禁忌证。

Exclusion criteria:

1. Severe artifacts, motion blur, or incomplete scanning range on CT images that affect pancreatic assessment. 2. Prior partial or total pancreatectomy. 3. Concurrent abdominal diseases that interfere with pancreatic observation, such as extensive peritoneal metastases, massive ascites, or severe bowel gas interference. 4. Pregnancy or lactation. 5. Inability to comply with the study procedures due to mental disorders, cognitive impairment, or other reasons. 6. Currently participating in another clinical trial that may interfere with this study. 7. Contraindications to contrast‑enhanced CT, including allergy to iodinated contrast media or uncontrolled hyperthyroidism.

诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

手术/活检病例:以术后组织病理学诊断作为最终金标准。 未手术病例:由多学科专家委员会依据影像、临床资料及≥2年影像随访结果形成共识诊断。 对照组:健康对照需CT正常且≥1年随访无胰腺疾病;非胰腺疾病对照需胰腺形态密度正常且随访无异常。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Surgical/biopsy cases: Postoperative histopathological diagnosis serves as the final gold standard. Non-surgical cases: Consensus diagnosis is established by a multidisciplinary expert committee based on imaging, clinical data, and at least 2 years of imaging follow‑up results. Control group: Healthy controls require normal CT findings and at least 1 year of follow‑up without pancreatic disease; non‑pancreatic disease controls require normal pancreatic morphology and density with no abnormalities during follow‑up.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

基于3D Vision Transformer架构的Pancreas-ViT CT影像基础模型辅助下的影像诊断。

Index test:

Imaging diagnosis assisted by the Pancreas-ViT CT foundation model based on the 3D Vision Transformer architecture.

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

接受腹部CT检查的疑似或确诊胰腺疾病(胰腺导管腺癌、急/慢性胰腺炎、胰腺囊性肿瘤等)患者及胰腺癌高危筛查人群。

例数:

Sample size:

1500

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Patients with suspected or confirmed pancreatic diseases (pancreatic ductal adenocarcinoma, acute/chronic pancreatitis, pancreatic cystic neoplasms, etc.) who undergo abdominal CT examination, as well as high‑risk screening populations for pancreatic cancer.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

例数:

Sample size:

0

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

None

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection: The investigator records the case information in excel and then double-checks the data. Data management: All information related to the identity of the subject will be kept confidential, and the relevant information will not be disclosed to the public except as permitted by relevant laws and/or regulations.
