Predominant mixed pattern in 78-year-old patient with BMI of 20. The mixed pattern (presence of consolidation, ground glass and reticular opacities in the presence of architectural distortion) is better depicted in the posterior, peripheral portions of lower lobes bilaterally. The arrowheads show a consolidation in the right lower lobe with contextual sand-like calcifications, better depicted in the image detail with mediastinal window in the upper right corner of a. a Dual-energy CT, 90/150Sn kV, ADMIRE 3. b High-pitch, dual-source acquisition with spectral shaping at 100 kV, filtered backprojection (LDCT0). c High-pitch, dual-source acquisition with spectral shaping at 100 kV, ADMIRE 3 (LDCT3). d High-pitch, dual-source acquisition with spectral shaping at 100 kV, ADMIRE 5 (LDCT5)
