Figure 6. — Comparison of image quality in infants with bronchopulmonary dysplasia (BPD). Axial PCD-CT images in 3 months old male with BPD, (A) slice thickness 1 mm, reconstruction kernel Bl56 and IR level 2, Q2, (B) slice thickness 1 mm, reconstruction kernel Bl64 and IR Q2, and (C) slice thickness 0.6 mm, reconstruction kernel Bl64 and IR Q2. (D) EID-CT coronal image (slice thickness 1 mm, reconstruction kernel Bl57 and IR 3). Note significant increase of sharpness and reduced noise from PCD-CT images, which facilitate assessment of typical BPD features, such as hypodense focal abnormalities (thin arrows) and linear fibrotic consolidations (arrowheads). Both scans are obtained with a dose-length product (DLP) of 4 mGy×cm.
