X光判讀筆記

如何判斷一張Chest X-Ray是否照得好
  1. Penetration: Spine要在心臟後方隱約可見
  2. Inspiration: Diaphragm至少要在8-9 posterior rib以下
  3. Rotation: Spinous process到兩端Clavicle等距
  4. Angulation:  Apical lordotic view的話Clavicle會高於3rd rib

辨識Abdomen內的Free air (Pneumoperitoneum)
有三個要注意的特徵:
  1. Air beneath the diaphragm (Supine or Left decubitus view)
  2. Falciform ligament sign
  3. Air on both sides of the bowel wall (Rigler's sign)

辨識Pleural effusion
  1. CP angle blunting
  2. Meniscus sign
  3. Pleural effusions shift mediastinal structures away from the side opacified.

Small bowel
  1. Central
  2. Valvulae extends across lumen
  3. Normal diameter= 2.5cm
  1. CP angle blunting
  2. Meniscus sign
  3. Pleural effusions shift mediastinal structures away from the side opacified.

如果trachea在mid-position、一邊白掉,也有可能是supine位的plural effusion + secondary lung collapse~所以氣管才會在中間

以上供參考XDD
