概括

前列腺成像质量 (PI-QUAL) v.2工具在评估前列腺多参数MRI扫描时显示出中等可靠性. 放射科医生之间的协议随着专业知识的提高,特别是对于DWI和DCE序列.

科学领域:

放射学放射学是一门学科.
医疗成像医学成像
质量评估的质量评估

背景情况:

多参数MRI (mpMRI) 对于前列腺癌的评估至关重要.
需要标准化的质量评估工具来确保可靠的mpMRI解释.
前列腺成像质量 (PI-QUAL) v.2是一个新的版本,旨在改善以前的质量指标.

研究的目的:

评估前列腺mpMRI的PI-QUAL v.2的读者间和读者内一致性.
评估放射科医生的专业知识如何影响PI-QUAL v.2评分的可靠性.
要将PI-QUAL v.2与其前身PI-QUAL v.1进行比较.

主要方法:

六位具有不同专业知识的放射科医生使用PI-QUAL v.2评估了50个前列腺mpMRI扫描.
在两周的间隔后重复评估,PI-QUAL v.1 也用于比较.
使用Gwet的AC1指数来量化读者间和读者内部的共识.

主要成果:

对于PI-QUAL v.2 (Gwet's AC1 = 0.55),读者之间的共识总体上是温和的,而专家读者之间的共识更高.
读者内部的一致性从中等到完美 (Gwet 的 AC1 = 0.43-1.00) 之间,并随着专业知识的提高而得到改善.
与T2w序列相比,DWI和DCE序列的复制性更高.

结论:

PI-QUAL v.2在标准化前列腺mpMRI质量评估方面表现出中等可靠性.

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...
