研究目的: |
本研究旨在通过整合 mpMRI 影像组学、血清非靶向代谢组学与重要临床指标,构建并验证一种可解释的多模态人工智能预测模型,用于提高 PSA 4–10 ng/mL(“灰区”)患者中前列腺癌的识别率与临床决策效率。具体目标为:提取并整合多模态特征,开发高性能的个体化风险预测模型;采用 SHAP 等可解释性方法构建模型解释框架,提升模型临床可解释性与医生采纳度;通过回顾性数据建模并在多中心前瞻性队列中验证模型的诊断性能与临床价值(包括提高穿刺阳性率与减少不必要穿刺的能力)。 |

|
Objectives of Study: |
This study aims to construct and validate an interpretable multimodal artificial intelligence prediction model by integrating mpMRI radiomics, serum untargeted metabolomics, and key clinical indicators, in order to improve the identification rate of prostate cancer and the efficiency of clinical decision-making in patients with PSA levels of 4–10 ng/mL (the 'gray zone'). The specific objectives are: to extract and integrate multimodal features and develop a high-performance individualized risk prediction model; to build a model explanation framework using interpretability methods such as SHAP, enhancing the model's clinical interpretability and physician acceptance; and to model retrospective data and validate the model's diagnostic performance and clinical value in a multicenter prospective cohort (including the ability to increase biopsy positivity rates and reduce unnecessary biopsies). |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data were collected using standardized case report forms (CRFs) and managed through an electronic data capture (EDC) system. Double data verification and data cleaning were performed before analysis. Imaging data were stored in a standardized and de-identified format, and serum samples were collected and processed according to standardized procedures. Data security and integrity were ensured by designated research personnel. |
