Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable semi-upright radiograph of the chest demonstrates a right - sided infusion port , with the tip terminating in the upper right atrium . Inspiratory volumes are slightly low . Cardio mediastinal silhouette is probably unchanged . Suspect mild cardiomegaly , with a calcified tortuous aorta . There is bilateral hilar prominence . Possible mild peribronchial cuffing is noted and the minor fissure is slightly thickened . There is mild prominence of interstitial markings at both bases . There is patchy opacity at both lung bases medially . There is no definite pleural effusion . No pneumothorax or obvious subdiaphragmatic air detected . Right upper quadrant surgical clips noted . Previously described ( CT ) described small pulmonary nodules that are not well depicted radiographically .
    OUTPUT:
    
Mild cardiomegaly is probably unchanged . Mild prominence of interstitial markings and minimal patchy opacity at both lung bases , of indeterminate acuity . This could reflect chronic changes , mild superimposed asymmetric CHF , or an early inflammatory process . No gross free air detected beneath the diaphragm . ( Subsequent abdominal CT identified trace pneumoperitoneum -- please see separate report of that study . )
