概括
扩散加权成像 (DWI) 比T2加权成像 (T2WI) 更好地预测负的多参数MRI扫描. 负的DWI结果可以表明完全负的检查,可能简化前列腺癌的诊断.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 医疗成像医学成像
背景情况:
- 多参数磁共振成像 (mpMRI) 对于前列腺癌的诊断至关重要.
- 评估单个MRI序列的负预测值可以优化诊断工作流程.
研究的目的:
- 为了确定完全负的mpMRI扫描的男性比例.
- 为了确定哪个序列,T2加权成像 (T2WI) 或扩散加权成像 (DWI) 最好预测整体阴性检查.
主要方法:
- 对492个符合PI-RADS v2.1的mpMRI扫描进行了回顾性分析.
- 放射学报告审查了病变的缺失或PI-RADS得分.
- 负扫描被前性地根据PI-RADS标准审查.
- 奇平方测试和后勤回归分析了T2WI和DWI的预测值.
主要成果:
- 在62.4%的扫描中,负的T2WI预测了负的DWI/DCE (OR 245.3,p < 0.001).
- 负的DWI预测了 88.9% 的扫描中负的T2WI/DCE (OR 76.4,p < 0.001).
- 经过对临床因素进行调整后,这些关联仍然显著.
结论:
- T2WI和DWI发现可以作为整体mpMRI结果的初步指标.
- DWI在预测负面整体考试方面表现出轻微的优势.
- 为了潜在的临床实施,需要进行进一步的研究.

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

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...
