20 years old female patient after closure of open foramen ovale with Amplatz´s occludor suffered for two days by chest pain was referred to chest CT-angiography. A scan of the thorax was performed on the SOMATOM Definition using spiral Dual-Energy data acquisition.
Pulmonary embolism affecting single segment – lateral segment of the right lower lobe – was found with corresponding deficit of perfusion on the pulmonary blood-volume (PBV) map.
Pulmonary blood-volume maps created during dual-energy data evaluation showed perfusion deficit within affected segment according to the sub-total occlusion of the segmental pulmonary artery by the embolus.
