Ultrasonic acoustic contrast can be used to show the vascular supply of tumors in the liver, pancreas, gallbladder and digestive tract during ultrasonography. Ultrasound-enhanced contrast agents: all of them are stable shell enveloped gas microbubble structures, which can function as blood pool contrast agents and can significantly enhance ultrasound back radiation, thus effectively enhancing blood flow echo. Pancreatic cancer lesions mainly show a lack of perfusion, a lack of blood supply tissue, and enhancement reveals sheets of several vessels within the occupying tumor with uneven enhancement and lamellar filling defects. The pseudotumor nodules of chronic pancreatitis showed a rich blood supply effect after contrast injection. After enhancement the nodules of chronic pancreatitis exhibit an enhancement heterogeneous enhancement effect with a significant peak. Endocrine tumors of the pancreas are also blood supply-rich effects and show enhancement effects after contrast injection.
