Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is rotated to the left on the frontal view . There is some external artifact projecting over the patient on the lateral view . Mild increase in interstitial markings bilaterally may be due to mild interstitial edema . It is difficult to exclude a very trace left pleural effusion . The cardiac silhouette is mildly enlarged .
    OUTPUT:
    
Suboptimal study as the patient is rotated to the left . Slight diffuse increase in interstitial markings bilaterally could be due to mild interstitial edema . If patient able , dedicated PA and lateral views with better patient positioning would be helpful for further evaluation .
