Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right internal jugular central venous catheter tip terminates at the SVC / right atrial junction . No pneumothorax is identified . Cardiac silhouette size is top normal . The aorta remains tortuous . The mediastinal and hilar contours are similar . There is mild pulmonary vascular congestion . Patchy opacities are noted in the lung bases , more pronounced in the left lung base , potentially atelectasis though infection or aspiration can not be excluded . There may be a tiny left pleural effusion . No pneumothorax is present .
    OUTPUT:
    
1 . Right internal jugular central venous catheter tip at the junction of the SVC and right atrium . No pneumothorax . 2 . Low lung volumes with mild pulmonary vascular congestion and patchy opacities at the lung bases , potentially atelectasis . Infection or aspiration particularly in the left lung base can not be completely excluded .
