概括
活检上的尖形前列腺癌 (PCa) 可能导致MRI上的疾病程度被低估. 这项研究发现,含有CBFM的瘤的癌症产量高于基于MRI大小的预期,影响了分期.
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.
- 病理学 病理学 病理学
背景情况:
- 前列腺活检上的Cribriform模式 (CBFM) 与高风险特征和不良结果有关.
- CBFM,假阴性MRI结果和组织病理学疾病负担之间的关联需要进一步调查.
研究的目的:
- 为了确定是否有CBFM模式的前列腺癌 (PCa) 与假阴性MRI发现有关.
- 评估MRI特征与PCa与CBFM中的组织病理疾病负担之间的关系.
主要方法:
- 在活检和活检前多参数MRI (mpMRI) 上对131名CBFM患者的回顾性分析.
- 活检核的分类为良性 (C0),没有CBFM的PCa (C1) 和带有CBFM的PCa (C2).
- 对MRI损伤尺寸和癌症核心长度 (CCL) 的相关性分析,以及对C1和C2损伤之间的CCL进行比较.
主要成果:
- 针对性活检 (TBx) 在76.3%的患者中确定了CBFM,而系统活检 (SBx) 在61.1%中确定了CBFM.
- 无论是TBx还是SBx,在较小的前列腺中都显示了相当的检测率.
- 在C1和C2病变中,MRI病变大小和CCL之间发现了显著的正相关性 (p<0.01).
- 对于特定的MRI T2和PI-RADS得分,C2病变显示出比C1病变更大的CCL,尽管MRI尺寸相似.
结论:
- 含有CBFM的瘤的程度可能会被mpMRI低估.
- 阳性CBFM瘤可以在活检上产生比MRI病变大小建议的更高的癌症负担.
- 准确的mpMRI估计对于分期和治疗规划至关重要;特别考虑CBFM模式是合理的.

Magnetic Resonance Imaging

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,...
