From: Dual-energy CT with virtual monoenergetic images and iodine maps improves tumor conspicuity in patients with pancreatic ductal adenocarcinoma

Fig. 6

Coronal reformatted image of a 66-year-old man with visually isoattenuating pancreatic ductal adenocarcinoma (PDAC) at the pancreatic head (arrows). Conventional polyenergetic image (PEI) revealed an isoattenuating mass, which was difficult to distinguish from the normal parenchyma (f). The 40-keV MEI (+) (a) showed the improvement of tumor conspicuity and margin delineation compared with 50–80 keV MEI (+) and PEI (b–f). On iodine maps (g, h), the NICtumor value of 2.2 mg/mL confirmed the diagnosis of tumor, which was significantly lower than the NICparenchyma value of 3.8 mg/mL. Combining low-keV MEI (+) and iodine maps improved the tumor conspicuity of isoattenuating PDAC, possibly enabling the early diagnosis
