Application of quantitative imaging technique in the diagnosis of pancreatic cancer / 中国基层医药

ABSTRACT

Pancreatic cancer is a malignant tumor,and the clinical manifestations are not characteristic,so it is difficult to diagnose at an early stage, and it has a poor prognosis. Image technology has been widely used in clinical,with mature technology,and the application of image technology not only confined to the image display,but also has become a hot spot of research, including dynamic contrast enhancement magnetic resonance imaging (DCE－MRI),intravoxel incoherent motion ( IVIM),CT perfusion imaging,which could analyze quantitatively the permeability and microvascular of lesions,to improve the sensitivity of diagnosis,and to assess quantitatively the effect of drugs,radiation and chemotherapy.
