概括

扩展前列腺MRI协议识别了重要的额外发现,包括影响患者管理的前列腺癌 (PCa) 相关异常. 虽然许多发现具有临床意义,但对非PCa相关发现的管理变化较少见.

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:

扩展前列腺MRI协议仍在使用,尽管对缩短方法的兴趣日益增加.
从扩展协议中评估额外发现 (AF) 的临床价值对于患者护理至关重要.

研究的目的:

为了评估前列腺扩大MRI协议的好处.
量化额外发现 (AF) 的数量和临床意义.
为了确定AFs对患者管理的影响.

主要方法:

对1282名接受前列腺核磁共振 (MRI) 的患者进行了回顾性分析.
基于与前列腺癌 (PCa) 的关系和临床意义 (1-3组) 的前列腺外发现的分类.
评估由重大AFs导致的管理变化.

主要成果:

在1240名患者中发现了5000多个AF.
与前列腺外PCa相关的AF发生在8.3%的患者中,改变了疾病阶段和治疗方法.
临床显著的AF (2和3组) 占所有发现的三分之一以上.

结论:

扩展前列腺MRI协议产生高临床意义的AF的流行率,PCa相关的和无关的.
与PCa相关的前列腺外AF在很大比例的病例中显著影响患者的治疗.
由于非PCa相关的重大AF造成的管理变化较少发生,这表明需要依赖于资源的协议选择.

Magnetic Resonance Imaging

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...
