概括

在关节 (TMJ) 疾病中观察到侧肌 (LPM) 附件的解剖学变化. 然而,磁共振成像 (MRI) 显示,患者的LPM附着类型和关节盘位移之间没有显著的相关性.

科学领域:

人体解剖学和生物力学
放射学放射学是一门学科.
牙科牙科是指牙科的专业.

背景情况:

侧肌 (LPM) 对于关节 (TMJ) 功能至关重要.
关节形态的解剖学变化可能会影响关节生物力学,并导致关节疾病 (TMD).

研究的目的:

调查不同类型的侧肌 (LPM) 附着物和关节盘在关节 (TMJ) 中的位置之间的关系.

主要方法:

通过使用磁共振成像 (MRI) 来对133名患者的266个TMJ进行了回顾性分析.
拉皮手机附件类型被分为三个类别 (I,II,III类型).
关节性圆盘位置被分类为正常,带有减少的圆盘位移 (DDwR) 或没有减少的圆盘位移 (DDwoR).

主要成果:

该研究确定了LPM附着类型的不同分布 (I型:27.8%,II型:62.4%,III型:9.8%).
盘位包括正常 (36.4%),DDwR (35.7%) 和DDwoR (27.9%).
在LPM附着类型和磁盘位移的存在或类型之间没有发现统计学意义上的相关性 (p=0.072).

结论:

观察到的LPM附件的解剖学变化与TMJ的关节盘位移没有显著的相关性.
需要使用先进的成像和功能分析进行进一步的研究,以澄清LPM形态在TMD病变发生中的作用.

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...

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
