Table 4 Catheter tip visualization and diagnostic confidence for chest pathologies. Six readers (2 radiologists, 1 neonatologist, 2 residents in radiology, and 1 last year medical student) evaluated 94 unprocessed and catheter-enhanced radiographs using a 5-point Likert scale (1 = poor catheter tip visualization, 5 = excellent catheter tip visualization). The 2 radiologists evaluated the diagnostic confidence for chest pathologies using a 5-point Likert scale (1 = poor diagnostic confidence, 5 = excellent diagnostic confidence)
