Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Inspiratory volumes are slightly low . Allowing for this , the heart is not enlarged . Aorta is minimally unfolded . No CHF , focal infiltrate or pneumothorax is detected . No pleural effusion is identified . No free air seen beneath the diaphragms . A nodular density measuring approximately 6 .5 mm in maximal diameter is noted at the right lung base laterally . This is in keeping with findings on the previous chest x-rays and with the calcified granuloma identified at the right lung base on the ___ abdominal CT . It does now measure slightly larger than on the ___ chest x-ray ( at which time it measured 5 .4 mm maximal diameter ) , but was clearly calcified on CT scan this could be due to technical differences .
    OUTPUT:
    
1 . No acute pulmonary process identified . In particular , no pleural effusion detected . 2 . Nodular density at the right lung base corresponds the calcified granuloma seen on the ___ CT scan .
