Good Morning Doc, I am 53 yrs, old, female, please help me understand the result of my chest x-ray conducted last December 22, 2013, as follows: Heart shows normal size & configuration. Pulmonary vascular markings are normal. There are linear, hazy infiltrates in both lung fields with predominance in the lower lobes. Diaphragm & lateral sulci are intact. Visualized osseous structures are unremarkable. Impression: Consider pneumonitis. Follow-up study is suggested. Is it not critical? Here is my email add: YYYY@YYYY
