Clinical Significance of Color Ultrasound, MRI, miR-21, and CA199 in the Diagnosis of Pancreatic Cancer

MRI images of patients with PC. (a) PC stage I: there is a nodular, slightly longer T1 shadow in the head of the pancreas, about 10 mm in diameter, with delayed enhancement and dilation of the main pancreatic duct. (b) PC stage II: there was a long T1 and T2 signal shadow in the body of the pancreas, with obvious hyperintensity on DWI and unclear boundary, 29 mm × 18 mm, and enhanced scanning showed mild enhancement and distal pancreatic duct dilation. (c) PC stage III: the pancreatic head is enlarged, and the pancreatic body and tail are atrophic. In the pancreatic head area, there are lump-like long T1 signal shadows, 43 mm × 40 mm, and mild enhancement. (d) PC stage IV: there were lump-like long T1 shadows in the body of the pancreas, with an unclear boundary, 40 mm × 85 mm, the enhancement degree was lower than that of the pancreatic parenchyma on an enhanced scan, and the adjacent peritoneal trunk was surrounded in it.
