胸部X-ray判讀基礎~~

一.判讀X光片: 首先要查看片子的基本資料:姓名.照射日期.姿勢(A-P View,' P-A View or Lateral View)品質  (KV+Density).

二.評估胸部X光成像質:  

             **技術品質Technical quality 

             1.Density orX-ray penetration :透過Heart陰影必須可見到Spinal cord.

             2.Position of the Scapulae:肩胛骨的位置應置於肺野之外.

             3.Rotation of the CXR(採正面):兩側鎖骨近胸骨內側端應與Spinous process等距.

             4. Degree of  inspiration(吸氣末憋氣):Anterior segment of the 6th rib

                                                                               Posterior segment of the 9th rib

三.如何判讀X-ray: 

            1.Airway

            2.TheHila:Hilum左邊的肺門高於右側 ;肺門的位置可因Lung collapse, Lung fibrosis                          or   Pneumonia  change.

           '3.Normal Lung Markings:Lung markings is Lung Vessels on X-ray present.

            4.Diaphragm:右邊高於左邊,因右邊有Liver關係, 右側Diaphragm最高點在內1/2處.

            5.Costophenic angle(C-P angle). 

            6.Heart:RA,SVC,Aortic Arch,LA,LV and Pulmonary Artery;Normal  Heart  size<50%;Cardiomegaly>50%.

          7.Skull.
