Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Extreme right lung apex excluded from the film . Allowing for this , no pneumothorax is detected . Pleural fluid is again seen extending along the left lung apex , probably similar in extent , allowing for differences in positioning . The tip of the ET tube is not well delineated , but it probably lies approximately 8 .7 cm above the carina , immediately below the level of the clavicular heads . NG type tube present , extending beneath diaphragm , off film . Right IJ central line --___ Swan - Ganz catheter --___ tip again noted in the region of the RV outflow tract --___ correlation requested . Left subclavian PICC line tip over proximal / mid SVC . Surgical ___ noted over the left chest . Subcutaneous emphysema is noted adjacent to the lower left chest wall . A linear density seen near the subcutaneous emphysema at the left chest base is of uncertain etiology or significance . No left - sided chest tube is identified . Extensive vascular plethora , diffuse vascular blurring , and some areas of confluent opacity are again noted in both lungs , similar to the prior study . Cardiac opacity also similar to the prior study . Right costophrenic angle excluded from the film .
    OUTPUT:
    
1 . Extreme right lung apex excluded from the film . Allowing for this , no pneumothorax is detected . Left apical pleural fluid again noted , similar to prior . 2 . Extensive interstitial and some alveolar opacities and retrocardiac opacity is similar to the prior film . This could reflect CHF with pulmonary edema . Possibility of an underlying pneumonic infiltrate would be difficult to exclude . 3 . No left - sided chest tube visualized . Clinical correlation is requested . 4 . Right IJ line --___ Swan - Ganz catheter . Please see comment above .
