Gray Scale Histogram Analysis of Carpal Tunnel Syndrome with Ultrasonography

Purpose: In this study, we aim to evaluate the diagnostic value of echogenicity ratio with histogram analyses. Materials & Methods: This retrospective study was performed on 22 patients with 44 hands. The patients had clinical presentations consistent with CTS, in at one hand. Quantitative ultrasound scanning and image capture were completed using a diagnostic sonography machine. For gray scale histogram analysis, image J software was used. Results: Mean flexor tendons histogram analysis echogenicity/Mean median nerve histogram analysis echogenicity was significantly high for 1,7 cutoff value. Conclusion: Mean FTE/MNE ratio may be a useful sonographic parameter for CTS.
