Spectral CT
Truth in beauty and beauty in layers...



Young male presented with influenza pneumonia, with suspected bacterial superinfection.

CT PE shows bilateral infiltrates, with markedly decreased perfusion on iodine maps (iodine density 0.4 mg/mL, versus 1.3 in normal lung).

Sputum cultures grew MSSA. 

CT from 2 weeks later shows bilateral extensive cavitary necrosis at site of previous infiltrates.
