Image scoring criteria¶
We obtained image quality scores for each CT image using abdominal soft-tissue windows (width/level: 350/40) from five experienced radiologists. The final human perceptual score for each image was calculated by averaging the scores assigned by the five radiologists. To ensure that the diagnostic image quality assessment criteria reflect the clinical relevance, we carefully defined them. These criteria can be found in the table below.
