Spectral pulmonary embolism

Aquilion ONE / PRISM Edition

This patient presented with shortness of breath. A spectral pulmonary CTA was performed and iodine maps generated. A pulmonary embolus is depicted in the 70 keV image (arrow). In the iodine map, a textbook wedge-shaped area of hypoperfusion is depicted in the corresponding lung region.

Congenital absence of right pulmonary artery

Aquilion ONE / PRISM Edition

This patient presented with difficulty breathing after undergoing implantation for a cardiac pacemaker. A Spectral CTPA exam was performed to rule out pulmonary disease. The Spectral iodine and effective Z maps show 90% reduced perfusion in the right lung due to a congenital absence of the right pulmonary artery.

Lung Nodule — Iodine Map Analysis

Aquilion ONE / PRISM Edition

Deep Learning Spectral CT delivers excellent energy separation and low-noise properties. Spectral DLR provides quantitative assessment of iodine uptake in lung nodules, which may allow for the differentiation between benign and malignant lesions.
