[|Human|] Hi. I had chest pa xray and the result was suspicious (l) paracardiac density. suggest lateral view. so I had again the chest lateral x ray and the result says no discernible definite parenchymal infiltrate lesion. by the way i m a high school teacher and this is a routinary check up for us. please enlighten me on this. thank you very much.
[|AI|]  Thanks for your question on Chat Doctor. Normal chest x-ray is taken in PA (PosteroAnterior) view.X-rays are not giving 3 dimensional pictures. It gives only 2 dimensional view. So depth of the lesion whether it is superficial or deep can not be diagnosed by PA film. So to overcome this lateral FIM is advice. In your x-ray PA view, some opacity is seen in left para cardiac region. So to rule out exact depth of the lesion, lateral view was done. And in lateral view, everything is ok. No need to worry much for this.
