Does high-Resolution Diffusion-Weighted Imaging improve the Diagnostic Accuracy of Dynamic Contrast-Enhanced Sinonasal Magnetic Resonance Imaging?
High-resolution DWI with ADC mapping significantly improved the diagnostic accuracy of dynamic contrast-enhanced sinonasal MRI at 3.0T. In addition, ADC values could distinguish benign lesions from malignant tumors in washout enhancement TICs.
These data show that degeneration of the deltoid muscle is of impact for clinical outcome. Although other factors like disuse or pain as a reason for muscular changes cannot be fully excluded, this degeneration might occur after time due to biomechanical changes after reversed arthroplasty. However, prospective studies with longer follow-up periods and repetitive assessment of muscle quality are necessary to further support these results.
