41-year-old female with history of pleuritic chest pain several weeks ago. The comparison chest radiograph performed on 5/4/2015 demonstrates no focal pulmonary opacities or pleural fluid. The ventilation images show a uniform distribution of activity on single-breath and wash-in images. There is no abnormal Xe-133 retention during the wash-out phase. Incidentally there is hepatic retention of contrast suggesting hepatomegaly and hepatic steatosis, which was also noted on prior abdominal MRI examination. The perfusion images show a physiologic distribution of pulmonary perfusion.
Normal ventilation and perfusion images. No evidence of pulmonary embolism.
