概括
多参数MRI (mpMRI) 显示黑人男性前列腺癌检测的灵敏度和NPV较低. 前列腺成像报告和数据系统 (PIRADS) 的得分小于3且PSA密度 (PSAD) 为0.09,可以改善黑人男性的活检决策.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
背景情况:
- 使用前列腺成像报告和数据系统 (PIRADS) 评分的多参数MRI (mpMRI) 具有90%的负预测值 (NPV).
- 在非黑人男性中,PSA密度 (PSAD) ≤0.15 ng/mL/cm3提高了mpMRI的NPV.
- 黑人男性患前列腺癌的患病率更高,这可能会影响mpMRI性能.
研究的目的:
- 评估黑人与非黑人男性mpMRI的灵敏度和NPV.
- 评估跨种族群体的前列腺癌检测mpMRI的潜在性能差异.
- 探索PSAD值,以实现黑人男性≥90%的敏感性.
主要方法:
- 黑人和非黑人男性接受mpMRI和MRI信息化活检的前性和后性分析.
- 包括286名黑人男性和965名非黑人男性,PSA≤15.0 ng/mL.
- 使用PIRADS版本2.0或2.1进行MRI评分.
主要成果:
- 黑人与非黑人男性的PIRADS<3显示较低的NPV (77.1%与87.6%) 和敏感性 (90.7%与96.3%) (P<0.05).
- 前列腺癌的检测是格里森等级组2至5.
- 在黑人男性中使用PSAD≥0.09用于PIRADS1-2病变,敏感性增加到92.9%.
结论:
- 在黑人男性中,PIRADS < 3 显示了降低的NPV和敏感性.
- 在具有负mpMRI结果的黑人男性中,PSAD值≥0.09可能更适合进行活检延期,以保持≥90%的灵敏度.

Sensitivity, Specificity, and Predicted Value

In healthcare diagnostics, laboratory tests play a crucial role in identifying and diagnosing a wide range of medical conditions. However, interpreting test results is not always straightforward. An abnormal test result does not always confirm the presence of a disease, just as a normal result does not guarantee its absence. To assess the reliability of these diagnostic tools, healthcare practitioners rely on two key statistical indicators: sensitivity and specificity.

Magnetic Resonance Imaging
4.9K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
