Fig. 4B. —81-year-old woman with lung cancer and pulmonary emphysema. Relative enhancement map obtained after oxygen inhalation shows little enhancement of tumor. Area with decreased oxygen enhancement (arrows) is much larger than accurate tumor itself. Relative enhancement map by oxygen inhalation indicates area of impaired regional ventilation possibly due to invasion of maximal tumor to surrounding tissue, disturbed perfusion by tumor in surrounding lung parenchyma, or scar. Maximum mean relative enhancement ratio by oxygen inhalation was 11.3%SI (percentage increase of signal intensity).
