Usually, MR imaging is not a routine examination for lung nodules because of the relatively low spatial resolution, but, I consider that the parallel imaging techniques will improve the depictability of lung nodules. Recent meta-analysis shows the usefulness of DWI for differentiating between malignant and benign lung nodules, including RA nodule. However, susceptibility artifacts may make it difficult to evaluate detailed ADC map. Therefore, I consider that the tumor size is an important factor for evaluation.
They may be difficult to distinguish by any technique short of serial imaging (to examine faster rate of growth of a malignant process) or biopsy. Historical imaging , lack of smoking etc. and a history of rheumatoid arthritis may assist.
