Synopsis

Keywords: Neurography, MSK

Motivation: Despite advancements in imaging, the correlation between malignancy and imaging features in neurogenic tumors remains unclear. Quantitative imaging could enhance diagnostic accuracy.

Goal(s): To evaluate the effectiveness of the MIXTURE technique in providing combined MR neurography (MRN) and T2 mapping for neurogenic tumors.

Approach: Nineteen patients with neurogenic tumors were assessed using MIXTURE MRI. Quantitative values (ADC, T2 values, and signal intensities) and qualitative evaluations by two radiologists were analyzed.

Results: Strong correlations between T2, ADC values, and their standard deviations highlighted the Antoni B component's influence. Detailed examination of the Antoni A component may aid malignancy assessment.

Impact: This study highlights MIXTURE MRI's potential to improve neurogenic tumor assessment through rapid, comprehensive imaging. Findings support further research on Antoni A components and could refine diagnostic protocols, aiding clinicians in evaluating tumor malignancy and optimizing patient management.
