Diagnostic value of dual-energy CT virtual monochromatic imaging for supraspinatus tendon injuries: a comparison with standard CT and MRI.

ABSTRACT:

Objectives

This study aimed to compare the diagnostic value of dual-energy computed tomography (DECT) virtual monochromatic imaging with that of standard computed tomography (SCT) in evaluating supraspinatus tendon injuries.

Materials and methods

This retrospective study involved patients who underwent a single-source DECT system, 3.0-T MRI, and shoulder arthroscopy within 14 days. Three radiologists independently and randomly evaluated SCT, mono+ 50 keV, mono+ 90 keV, and MRI images to detect supraspinatus tendon tears and recorded their diagnostic confidence. Regions of interest were delineated to measure the CT attenuation values of torn, degenerated, and normal tendon regions in SCT, mono+ 50 keV, and mono+ 90 keV images.

Results

A total of 100 patients with supra
