Summary
This study introduces a novel method using near-infrared spectroscopy and multi synchrosqueezing transform to accurately estimate pancreas shrinkage by analyzing beta cell function and insulin secretion. This technique offers an 88% accurate, non-invasive approach for early detection of pancreatic changes.
Area of Science:
- Biomedical Engineering
- Medical Imaging
- Spectroscopy
Background:
- Pancreas structure estimation traditionally relies on MRI and ultrasound.
- Pancreatic changes, including islet cell death, affect insulin secretion.
- Diabetic individuals exhibit varying beta cell insulin secretion.
Purpose of the Study:
- To propose a novel method for estimating pancreas shrinkage.
- To correlate beta cell insulin secretion with pancreas structure.
- To enable early detection of pancreatic apoptosis.
Main Methods:
- Near-infrared (NIR) spectroscopy to detect islet cells in the pancreas.
- Multi synchrosqueezing transform (MSST) for analyzing NIR signals.
- Multivariate regression model using Root Mean Square (RMS) and kurtosis to evaluate pancreas shrinkage.
Main Results:
- NIR spectroscopy signals were acquired from 40 participants (20 diabetic, 20 non-diabetic).
- Pancreas shrinkage was estimated with 88% accuracy.
- Results were validated using MRI pancreas images.
Conclusions:
- The proposed method accurately estimates pancreas shrinkage.
- This technique aids in the early detection of pancreatic apoptosis.
- Pancreas shrinkage is linked to reduced insulin secretion and blood glucose variability in diabetics.
