Yes bon you are right. if there is any abnormality, they asked for re-take. But in my and most of case if there is any scar in lungs that remain whole life, so radiologist asks for some lab test, which shows that person having disease or not. My lab tests are clear only x-ray showing some abnormality.

I think if you are in qatar better to conuslt privately with dr. radilogist , who is working in same medical center.

any one want to share any info.. we'll appreciate.
