Outline of Final Research Achievements

There is no existing worldwide published method for mediastinum compartment classification based on transverse section images for the differential diagnosis of mediastinal tumors. We proposed a new method for anatomic mediastinal compartment classification using transverse section computed tomography (CT) images, using four compartment models (JART method). In the present study, we retrospectively analyzed 445 of 500 pathologically proven mediastinal mass lesions, and categorized them into the proposed four compartments by consensus reading. Mass lesions were classified into compartments based on the location of the lesion centroid, and each lesion was satisfactorily categorized into a compartment. Our findings showed that the newly proposed mediastinal compartment classification using transverse images appears to be user-friendly enough for practical clinical application and may be helpful in differential diagnoses (Oncol Rep, 2014;31:565-572).
