Hello. My mom had a chest xray yesterday that showed small nodular density in the right upper lung . The radiologist recommended another xray done with more oblique views, which she did today, to see if this may be an artifact, and again, it showed the same thing. Her doctor now recommends to have a CT scan. Will CT differentiate between benign and malignant process? Is it better to have it with contrast or without? Thank you! We worry what this density could represent. Oh, her last xray for comparison was in 2003 and was completely normal...
