BMJ Case Reports, 2015 A 61-year-old woman was under treatment with a combination of methotrexate and leflunomide for seropositive rheumatoid arthritis (RA) for the past 6 years. She presented to us 6 months earlier with grade 1 dyspnoea of 3-month duration. She was a non-smoker. On evaluation, her vitals, and respiratory and cardiovascular system were normal.

Automated identification of lung nodules [PDF]
2008 IEEE 10th Workshop on Multimedia Signal Processing, 2008 A system that can automatically detect nodules within lung images may assist expert radiologists in interpreting the abnormal patterns as nodules in 2D CT lung images. A system is presented that can automatically identify nodules of various sizes within lung images. The pattern classification method is employed to develop the proposed system.
