Assessment of Pancreatic Physiological and Pathological Characteristics Based on Spectral CT

Condition(s) studied

Investigational drug(s) / intervention(s)

The post-processing generated after scanning is converted into energy spectrum image data (SBI): It will not open special sequences for patients, will not increase the cost of diagnosis and treatment, will not increase radiation exposure during enhanced CT scanning, and will not affect the normal diagnosis and treatment process of patients throughout the process.

Study summary

Patients who visited our hospital for various reasons from January 2024, underwent CT scans involving the pancreas, and were eligible for spectral post-processing reconstruction were included in the study. This research collected spectral CT data related to the pancreas at different phases, as well as physiological and pathological states for these patients. Quantitative analysis was conducted on post-processed data under different physiological and pathological states, including parameters such as pancreatic iodine uptake features, attenuation interval slopes, and extracellular volume size. In conjunction with general patient status, biochemical tests, and postoperative pathological results, the study aimed to identify correlations between parameters, develop models, and conduct research by comparing traditional CT data, which could be matched with spectral CT from the PACS database since its establishment.
