背景情况:
- 在MRI上非突触性炎症是多性肌痛类风湿症 (PMR) 的特征性发现.
- 这种成像功能对PMR具有显著的诊断潜力.
研究的目的:
- 描述PMR患者肩带中的炎症性MRI发现.
- 用MRI来区分PMR与肩带疼痛的其他原因.
主要方法:
- 追溯分析 496 个增强对比度的肩带MRI 扫描 (122 PMR, 374 个非PMR).
- 两位失明的放射科医生评估了6个非突和3个突部位的炎症.
- 评估了用于PMR诊断的突和非突炎症的辨别能力.

791
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.

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...
