概括
与PSA相结合的放射性分析显示,从偶然的[18F]FDG吸收 (IPU) 中识别前列腺癌 (PCa) 是有前途的. 机器学习 (ML) 模型可以帮助区分非PCa IPU,从而减少不必要的调查.
科学领域:
- 核医学就是核医学.
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
背景情况:
- 在PET/CT扫描上偶然的前列腺[18F]FDG吸收 (IPU) 需要准确的表征.
- 在IPU中,将前列腺癌 (PCa) 与良性发现区分开来是临床上重要的.
研究的目的:
- 评估偶发性前列腺[18F]FDG吸收 (IPU) 的诊断价值.
- 探索放射学和机器学习 (ML) 来预测PCa及其从IPU的等级.
主要方法:
- 从两个机构 (2015-2021) 来用IPU进行[18F]FDG PET/CT扫描的回顾性分析.
- 根据活检结果将患者分为PCa和非PCa组.
- 进行了临床数据,PET/CT成像特征和放射性分析.
- 开发了五种ML模型来区分PCa与非PCaIPU,并预测ISUP等级.
主要成果:
- 31名活检患者中有18名患有PCa.
- 前列腺特异性抗原 (PSA) 和放射性特征 (CT和PET) 在PCa和非PCa组之间显著不同.
- 基于CT的ML模型显示出良好的性能 (NPV 0.733-0.867).
- 从PET衍生的随机森林模型显示PCa检测的高NPV (0.933).
- 放射学没有准确地预测ISUP等级.
结论:
- 放射性分析,特别是与PSA相结合时,显示了区分PCa与非PCaIPU的潜力.
- 机器学习模型可以有效地识别非PCa IPU,从而可能避免进一步的侵入性程序.

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
