概括

大多数MLB选秀投手都有异常的肘部MRI,经常显示侧带 (UCL) 变化. 这些发现是常见的,可靠的评估投手手肘的健康状况.

科学领域:

骨科运动医学运动医学
放射学放射学是一门学科.
棒球表现分析棒球表现分析

背景情况:

选秀前的肘部磁共振成像 (MRI) 是用于大联盟棒球 (MLB) 投手的.
评估MRI发现对于评估投手手肘病理至关重要.
了解MRI发现与侧带 (UCL) 撕裂之间的关联是很重要的.

研究的目的:

为了评估MLB选秀投手在选秀前的肘部MRI发现.
为了确定肘部病态的患病率及其与UCL撕裂的关联.
评估常见MRI病理的观察者间可靠性.

主要方法:

审查了MLB投手在选秀前 (2011-2017年) 没有识别的肘部MRI图像.
两位作者对UCL骨化,外观,加厚和撕裂 (部分/全部厚度) 的MRI进行了分级.
评估的其他病理包括肌肉疲劳,肌撕裂,骨质细胞和骨应激反应.

主要成果:

70%的投手呈现MRI异常. 70%的投手呈现MRI异常.
侧带 (UCL) 加厚在20%的投手中存在.
3%的人有全厚UCL撕裂,24%的人有部分厚度撕裂,位置不同.

结论:

大多数MLB选秀前景显示肘MRI发现异常,经常涉及UCL.
对于诊断常见的MRI病理的观察者间可靠性是可以接受的.
预选肘部MRI是识别投手潜在问题的一个有价值的工具.

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...
