The early detection, diagnosis and timely treatment of Pancreatic cancer have very important significance for reducing the patient's mortality and improving survival quality. Therefore, Computed Tomography scan is very important for Pancreatic cancer.

First, Spiral CT enhance scan technology.

Usually, it is three times scan: arterial phase(23-30s), pncreas phase(40-45s), prtal phase(60-70s), but many experts think that pancreas strengthen isn't ideal in arterial phase and small lesions is difficult to find, thus, it isn’t helpful for diagnosis.

Second, Enhancement spiral CT dynamic scanning

Third, Multidetector-row Spiral CT scan

Data information of Multidetector-row Spiral CT is convenient for MIP, 3D and vscular imaging post-processing because of fast scan speed and thick or thin of scanning layer. It makes not only the larger blood vessels show clearly, but also it can display small blood vessels. In addition, it can reflect that whether pancreatic cancer infringe blood vessels around or not.

Fourth, CT Perfusion imaging technology

The choice of level: Do the plane scanning firstly and choose the best level to do perfusion inspection. In this process, you should choose the largest level of lesions. The conventional CT reflects morphological changes, but CT perfusion imaging can reflect exocrinosity function and pathological changes on the before basic, then it combined with form diagnosis and function diagnosis, it is helpful for pancreatic disease early diagnosis and identify diagnosis. Pancreas perfusion imaging does dynamic scanning for selected level and gets a series of dynamic images; After that, analysis and contrast the corresponding density change of every pixel and acquire every pixel time and density curve. At last, It gets blood perfusion situation after computer software processing.

Therefore, Spiral CT is a imaging method of no wound and fast and has an important role for pancreatic cancer diagnosis and resectable evaluation before surgery, it is a examination way which is worth for promoting. Surgery development and surgery evaluation standards will promote image development.
