Introduction
In general, CT differences between pancreatic cysts and pancreatic cancer include aspects such as morphology, density, margins, contrast enhancement, and surrounding structures. Patients with pancreatic diseases should get adequate rest, avoid overexertion and staying up late, drink plenty of water, maintain a light diet, and avoid smoking, alcohol, and spicy foods. Patients are advised to seek medical attention promptly if they experience any discomfort.
Generally, CT differences between pancreatic cysts and pancreatic cancer include aspects such as morphology, density, borders, contrast enhancement, and involvement of surrounding structures. Specific details are as follows:
1. Morphology
Pancreatic cysts typically have a regular shape, appearing round or oval, whereas pancreatic cancer often has an irregular shape with infiltrative growth.
2. Density
The density of pancreatic cysts is usually uniform, while pancreatic cancer may show heterogeneous density, with possible calcifications, hemorrhage, or necrosis.
3. Borders
Pancreatic cysts usually have well-defined borders, clearly demarcated from surrounding tissues, whereas pancreatic cancer may have poorly defined borders with indistinct margins from adjacent tissues.
4. Contrast-enhanced scanning
In contrast-enhanced scans, pancreatic cysts typically show no enhancement or only mild enhancement, whereas pancreatic cancer often exhibits明显 non-uniform enhancement.
5. Surrounding structures
Pancreatic cysts generally do not compress or invade surrounding organs or blood vessels, whereas pancreatic cancer may cause compression or infiltration of adjacent organs or vessels.
Patients with pancreatic diseases should ensure adequate rest, avoid overexertion and staying up late, drink plenty of water, maintain a light diet, and avoid smoking, alcohol, and spicy foods. If discomfort occurs, patients should seek medical attention promptly and receive standardized treatment under the guidance of a physician, which helps promote recovery.
