Evaluation of emphysema using three-dimensional computed tomography: association with postoperative complications in lung cancer patients

Autor: Kenichi, Kawakami, Shingo, Iwano, Naozumi, Hashimoto, Yoshinori, Hasegawa, Shinji, Naganawa

Publikováno v: Nagoya Journal of Medical Science

Three-dimensional computed tomography (3D-CT) enables in vivo volumetry of total lung volume (TLV) and emphysematous low-attenuation volume (LAV) in patients with chronic obstructive pulmonary disease (COPD). We retrospectively investigated the corre
