Assessment of CNR for pancreatic ductal adenocarcinoma in a 56-year-old female patient. A An arterial phase axial contrast-enhanced CT image from the high-resolution protocol reveals a 2 cm hypo-attenuating lesion with a mean Hounsfield Unit (HU) value of 85.8. B The mean HU value for the pancreatic parenchyma was 215.47. C Noise level, characterized by the mean standard deviation of subcutaneous fat attenuation, is measured at three distinct locations (one shown here), yielding a value of 13.5. From these measurements, the CNR for the pancreatic ductal adenocarcinoma is calculated to be 9.6
