Pulmonary edema is a condition of excess fluid within the lung that most frequently is caused by a backup in pulmonary circulation commonly associated with congestive heart failure (CHF).A commonly cause is coronary artery disease, in which blood flow to the heart muscle is restricted. This weakens the heart and results in inadequate pulmonary circulation, causing a backup of blood in the lungs. The condition is seen on chest radiographs as a diffuse in crease in radio density in the hilar regions fading toward the periphery of the lung, and as increased air-fluid levels with horizontal beam projection in more severe conditions.

Reactivation (secondary) tuberculosis usually develops in adults and generally is first evident on radiography bilaterally in the upper lobes as irregular calcifications that are mottle in appearance. Upward retraction of the hila is frequently evident. As healing occurs, fibrous tissue develops with calcification surrounding the region and leaving a type of cavity that can be seen on tomograms of this region. AP lordotic projections are frequently requested for visualization of calcifications and cavitations of apices and upper lobes.

    肺水腫是多餘的液體在肺部最常見的是引起肺循環備份通常伴有充血性心臟衰竭(CHF)的條件,一個常見的原因是冠狀動脈疾病,其中心臟肌肉的血液流動受到限制。這削弱了心臟和肺循環不足,結果,導致血液在肺部的備份。該條件被認為是胸片肺門衰落向肺的外週,所增加的空氣流體高度與水平光束投射在更苛刻的條件下的區域中的無線電密度摺痕作為漫反射。

    重新激活(二級)結核病通常在成人的發展,一般是第一個明顯的雙側肺上葉斑駁的外觀為不規則鈣化,X光片檢查。肺門向上回縮經常是顯而易見的。癒合時,纖維組織的發展與鈣化周圍的區域,並留下一個不同的空腔,在此區域中的X線斷層圖上可以看出。 AP前凸的預測經常會要求尖和上葉鈣化和空化的可視化
