Fig. 4 — Box and Whisker plots show the results of subjective image ratings by radiologists regarding the diagnostic reader confidence while assessing ground-glass opacity (GGO), general image quality, the contrast between GGO and unaffected lung parenchyma, and subjective time-efficiency of minimum intensity projection (MinIP) reconstructions and multiplanar reformat (MPR) series. Medians are displayed as horizontal bold black lines. MinIP reconstructions were rated as distinctly better than standard MPR images with regards to diagnostic confidence, contrast and subjective time-efficiency (average difference in scores, 0.33, 0.67 and 0.77, respectively, all comparisons P < .001), while ratings for general image quality were only slightly better for MinIP reconstructions compared to MPR series (average difference in scores, 0.14, P < .001).
