Data are shown as numbers of patients. PVL, paravertebral line; PAL, posterior axillary line; AAL, anterior axillary line; STN, sternum. Examinations of the left lower anterior lung areas were compromised by cardiac shadows in two patients. Views of the right (n = 3), left (n = 2), and both (n = 2) upper posterior lung areas were limited by scapular.
