Introduction:
Recent advancements in medical imaging, such as point shear wave elastography (pSWE), offer non-invasive methods to assess tissue stiffness and structural changes. This study explores the use of pSWE to evaluate pancreatic stiffness and dimensions in three different pancreas parts.
Methods:
This study was conducted at diagnostic radiology department, King Abdulaziz University Hospital, Jeddah, between June 2022 and November,2022. Thirty-one diabetic patients and thirty-one healthy controls were included. Ultrasound pSWE examination was performed using a ultrasound system (Philips Elite Epic 7) to measure stiffness across different pancreatic parts. Pancreatic stiffness was quantified in meters per second (m/s), and the dimensions of each pancreatic part were recorded. Different parameters, including age, sex, height, weight, body mass index (BMI), and comorbidities, were collected and analyzed.
Results:
Diabetic patients exhibited significantly higher shear wave velocities (SWVs) compared to healthy controls, indicating increased pancreatic stiffness. The mean shear wave velocity was 1.7 m/s in diabetic versus 0.6 m/s in controls (p < 0.001). Additionally, the pancreatic head dimensions were significantly large in diabetic patients (2.1 cm vs. 1.8 cm; p = 0.003), while the body and tail part showed no significant differences. A positive correlation was found between SWVs and BMI.
Conclusion:
The findings underscore the potential of pSWE as a non-invasive diagnostic tool for early detection and monitoring of diabetes-related pancreatic alterations. Assessing pancreatic stiffness and dimensions through pSWE can help in identify patients at risk for pancreatic complications and optimize management strategies.
Implications For Practice:
Point shear wave elastography (pSWE) could be a useful, non-invasive tool for early detection of pancreatic changes in diabetic patients, identifying those at risk for complications. Integrating pSWE into routine diabetes check may enhance early interventions and improve outcomes.
