Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest has been obtained with patient in sitting semi-upright position . Comparison is made with the next preceding PA and lateral chest examination of ___ . High - positioned diaphragms are explained by poor inspirational effort rather significant when compared with the previous examination where deep inspiration was accomplished . Heart size can not be assessed but probably unchanged and within normal limits . No pulmonary vascular congestion is identified and no evidence of acute pulmonary infiltrates found . The lateral pleural sinuses are free . Again noted is the rather local and marked scoliosis at the transition between thoracolumbar spine resulting in a right basal prominence could be wrongly interpreted as pulmonary density on the frontal view . This is , however , not the case .
    OUTPUT:
    
Unchanged chest findings in comparison with the next preceding PA and lateral chest examination . Thus , no evidence of new acute infiltrates as can be identified on portable single view examination .
