Radiologists rated this cleaning method as better at removing noise and artifacts from low-dose CT scans compared to other methods.
Scientific Claim
The SADiff model achieves better noise reduction and artifact reduction in low-dose CT images compared to other denoising methods, as measured by radiologist evaluations on a five-point scale.
Original Statement
“The radiologist independently scored each image slice on four criteria, including noise reduction, artifact reduction, structure preservation, and overall quality, using a five-point scale (1 = unacceptable, 2 = barely clinically acceptable, 3 = satisfactory, 4 = very good, and 5 = excellent).”
