My husband s report from a pet scan said the lungs are moderately inflated there is vascular crowding in the left lower lobe and poster segment of the left upper lobe presumable related to the patients absent pericardium. What does all this mean ? Thank you
PET scan indicates metabolic activity in the body. Areas which are infected or tumors are more metabolically active and are highlighted with PET Scan. The report you are indicating is from a PET/CT scan. And what you are reporting does not have any obvious abnormality. Did your husband have a previous surgery?
