Area of Science:

  • Medical Imaging
  • Computer-Aided Diagnosis
  • Radiology

Background:

  • Vertebral compression fractures (VCFs) are critical indicators of osteoporosis and can result from benign or malignant causes.
  • Accurate detection and classification of VCFs are essential for patient management and treatment planning.

Purpose of the Study:

  • To develop a computer-aided diagnosis (CAD) system for detecting, labeling, segmenting, and classifying lumbar vertebral bodies (VBs).
  • To differentiate between normal VBs, benign VCFs, and malignant VCFs using image features.

Main Methods:

  • Image preprocessing followed by feature extraction including morphological, shape, and angular features for segmentation.
  • Extraction of shape and statistical texture features from segmented VBs for classification.
  • Comparison of automated results with expert-defined ground truth.

Main Results:

  • The system achieved a Dice Similarity Coefficient (DSC) of up to 94.27% for VB segmentation.
  • Classification accuracy reached 95.34% when combining shape and texture features.
  • The system demonstrated high performance in differentiating between normal, benign, and malignant VCFs.

Conclusions:

  • The developed CAD system shows significant potential for accurate analysis of VCFs.
  • The integration of shape and texture features enhances classification performance.
  • This technology can aid clinicians in diagnosing and managing vertebral compression fractures effectively.
