- 在瘤学瘤学.
背景情况:
- 前列腺癌的诊断通常依赖于PSA测试和随后的MRI扫描.
- 当前的PSA导入的MRI协议可能会错过临床显著的前列腺癌 (csPCa).
- 将"初级"MRI (仅前列腺MRI) 与"PSA-gated"MRI进行比较对于优化查至关重要.
研究的目的:
- 为了比较前列腺癌查的初级MRI和PSA导入MRI之间的癌症检测率 (CDR).
- 使用这两种查方法评估临床显著前列腺癌 (csPCa) 和临床无意义前列腺癌 (ciPCa) 的检测.
主要方法:
- 在主要数据库 (PubMed,Embase等) 进行了系统的文献搜索. 从2000年开始到2024年.
- 研究包括没有先前风险分层的成年男性,提取csPCa (ISUP等级组≥2) 和ciPCa (ISUP等级组1) 的CDR数据.
- 还提取了活检率以进行比较.
主要成果:
- 与PSA导入的MRI相比,初级MRI查对所有前列腺癌的CDR显著更高 (8.49%对1.88%) 和csPCa (5.93%对1.15%).
- 两种方法之间在ciPCa检测上没有发现显著差异.

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...

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,...

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...
