tree in bud opacities treatment

The sensitivity and specificity of tree-in-bud and patchy shadows for the diagnosis of Mycobacterium abscess lung disease was further analyzed and we found that the sensitivity and specificity of patchy shadows was 635 3352 and 181 1372 respectively and was 423 2252 and 819 5972 for small centrilobular tree-in-bud development. The latter etiology is often overlooked but is important to consider in patients with a cancer history to avoid delays in diagnosis and treatment.
