While the laterolateral radiograph appears to be of sufficient quality, the lung zones are lacking contrast due to overexposure in the PA x-ray - highly suggestive of a kV or mAs error. The DICOM header of the exams contains these pieces of information, which in this case revealed that the kV (120) was appropriate, however, the PA radiograph was also inappropriately taken with a preset designed LL ones, resulting in overexposure due to the higher mAs setting of the latter. For comparison the mAs of the PA radiograph was 6.5 while, a the previous similar x-ray was obtained with a much lower value (2 mAs)
