概括

新投手的斜旋转 (TORC) 视图MRI序列增强了对投运动员旋转和部损伤的诊断信心和一致性. 这种专门的视图提高了在评估损伤大小时的读者间可靠性.

科学领域:

整形外科手术整形外科手术
放射学放射学是一门学科.
运动医学运动医学

背景情况:

头部运动员经常经历旋转和部损伤.
脊上旋转和囊膜结构通常很难用标准的MRI测序来可视化.
投手的斜旋转手套 (TORC) 视图是为了改善这些特定的肩膀结构的可视化而开发的.

研究的目的:

评估是否添加TORC视图到标准MRI序列可以改善对旋手腕病理和投运动员的腹异常的诊断评估.
评估TORC视图对诊断信心和读者间可靠性的影响.

主要方法:

从MLB投手 (2019-2021) 的肩膀MRI的回顾性审查.
纳入标准:标准和TORCMRI测序,年龄在18-35岁之间.
肌肉骨放射科医生和两名骨科外科医生用TORC视图和没有TORC视图解释了MRI.

主要成果:

根据TORC的观点,Supraspinatus,Infraspinatus和Labral撕裂的分类进行了轻微的重新分配.
个别读者对信号大小的测量有显著差异 (p < 0.05),在TORC视图上通常更大,但聚合测量显示没有显著差异 (p = 0.197).
信号大小的读取器间可靠性得到改善 (ICC 0.47 至 0.73),三种读取器中的两个读取器的诊断信心增加 (p < 0.001).

结论:

添加TORC视图增强了读者对定量信号大小评估的信心和读者之间的可靠性.
在TORC视图没有引入系统的变化,在分类肌或部分类.
TORC序列是标准肩部MRI协议的宝贵补充,用于提高精英空投运动员的解释一致性和信心.

关键词:

运动员的头顶运动员.职业棒球运动员是职业棒球运动员.在TORCMRI视图中,可以看到TORCMRI视图.

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...

Ultrasonography

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
