Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The frontal view is suboptimal due to patient body habitus . There are also relatively low lung volumes . No pleural effusion is seen . There is no evidence of pneumothorax . The cardiac silhouette is mildly enlarged . Relative opacity projecting over the medial right lung base is nonspecific , could be due to vascular crowding , however , underlying consolidation not excluded .
    OUTPUT:
    
Suboptimal study due to underpenetration due to patient body habitus . Mild cardiomegaly . Relative opacity at the medial right lung base may be due to overlapping vascular structures , although consolidation is not excluded in the appropriate clinical setting .
