概括
垂直MRI在骨盆器官缩 (POP) 患者中显示出显著的升高肌肉 (LAM) 损伤,通常在卧式扫描中错过. 仰卧式成像低估了 iliococcygeal 肌肉 (ICM) 的损伤,而 pubococcygeus 肌肉 (PCM) 的评估只能在仰卧式位置进行.
科学领域:
- 盆地图像成像 盆地图像成像
- 肌肉骨的MRI是指肌肉骨的MRI.
- 女性的盆腔医学.
背景情况:
- 骨盆底肌损伤是骨盆器官脱落 (POP) 的关键因素.
- 当前的成像协议可能无法完全捕捉到左侧肌肉 (LAM) 的损伤.
- 直立成像可能会揭示以前未被检测到的骨盆底异常.
研究的目的:
- 用MRI来比较躺卧和直立的上升肌肉 (LAM) 损伤.
- 为了评估垂直MRI对盆地肌肉损伤的诊断准确性.
- 为了评估成像位置对检测阴肌 (PCM) 和阴肌 (ICM) 损伤的影响.
主要方法:
- 64名POP患者进行了仰卧和直立的MRI.
- 一个经过验证的协议评估了PCM损伤 (仅靠背).
- 一个新的协议评估了ICM损伤,并对仰卧和直立姿势进行了验证 (ICC分别为0.68和0.81).
主要成果:
- 垂直式MRI显示,与卧卧式 (6.3%,p<0.001) 相比,主要ICM损伤显著更高 (51.6%).
- 在59%的病例中,仰卧成像低估了ICM损伤.
- 在85.9%的患者中发现了PCM或ICM的重大损伤,其中32.8%的患者对两者都有损伤.
结论:
- 图像位置显著影响LAM在POP中损伤的评估.
- 垂直MRI对于准确的ICM损伤评估至关重要,而卧式MRI对于PCM评估更优越.
- 标准的卧床成像可能导致关键的盆地肌肉损伤的诊断不足.

Assessment of the Rectum and Anus
110
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

Assessment of the Abdomen II: Percussion
137
Percussion is a fundamental technique used to assess the liver, spleen, and abdominal organs by tapping the abdomen and interpreting the resulting sounds. This method helps identify fluid, distention, and masses through variations in sound, such as the high-pitched tympany of air-filled areas and the dullness of solid masses. Understanding how to percuss these organs provides valuable information for healthcare professionals in diagnosing conditions early.

Anatomical Positions
9.1K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Assessment of the Abdomen III: Palpation
214
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...
