CT evaluation of the equivocal pulmonary nodule

摘要: In the setting of a questionable pulmonary nodule demonstrated by conventional radiographs, place CT in diagnostic algorithm is not well established. We reviewed our experience 50 consecutive patients referred to for "possible nodule." From chest radiographs we noted location, maximum dimension, presence on one or both views, and previous radiograph (greater than 1 year old), nodules were categorized as "likely" "unlikely" be real parenchymal lesions based radiographic appearance. Of total 56 nodules, no abnormality 21 cases, 16, scarring, atelectasis, infiltrate 11, normal structural variants 8. True statistically significantly more frequently disease, but this was magnitude clinically useful. Based analysis various features equivocal their subsequent outcomes, suggest radiologic approach nodule.
