本综述考察了PI-RADS 3病变在前列腺癌 (PCa) 检测,突出影响其评估的因素和改进诊断工具的需要. 进一步的研究对于管理这些模两可的发现至关重要.
科学领域:
- 放射学 放射学是一门学科.
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 在瘤学瘤学.
背景情况:
- 前列腺成像已经发展,PI-RADS (前列腺成像报告和数据系统) 成为评估前列腺癌风险的标准.
- PI-RADS 3病变对临床显著的前列腺癌 (csPCa) 提出了模两可的发现,这给诊断带来了挑战.
- 在PI-RADS 3病变中,cspca的检测率在10%到35%之间.
研究的目的:
- 审查前列腺MRI中的PI-RADS 3病变的技术和临床考虑.
- 讨论影响PI-RADS评分的因素,包括MRI质量和放射科医生的专业知识.
- 探索扩散权重成像 (DWI) 和双参数MRI (bpMRI) 在评估PI-RADS 3病变中的作用.
主要方法:
- 对PI-RADS v.2.1对外围区域 (PZ) 和过渡区 (TZ) 病变的更新定义的审查.
- 分析MRI质量和放射科医生经验对PI-RADS 3病变报告的影响.
- 评估DWI在评估TZ病变和潜在的得分升级中的作用.
- 考虑bpMRI作为特定患者群体的替代方案.
主要成果:
- PI-RADS 3病变报告受MRI质量和放射科医生的专业知识的影响.
- 更新的PI-RADS v.2.1定义影响了PZ和TZ的评分.
- DWI可以帮助评估TZ病变,可能将PI-RADS 2病变升级到3.
- bpMRI可能会增加需要活检的不确定的病例.
结论:
- 管理PI-RADS 3 (含糊不清) 前列腺MRI发现的患者仍然是一个临床挑战.
- 需要利用分子/成像标记物和人工智能进行进一步的研究,以更好地选择患者进行活检.
- 标准化PI-RADS 3病变的评估和改善诊断准确性对于最佳的前列腺癌管理至关重要.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Positron Emission Tomography
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...
