Added-value of advanced magnetic resonance imaging to conventional morphologic analysis for the differentiation between benign and malignant non-fatty soft- tissue tumors
European Radiology Sep 07, 2020
Dodin G, Salleron J, Jendoubi S, et al. - This study was undertaken to assess the added value of DWI, qualitative proton MR spectroscopy (H-MRS) and dynamic contrast-enhanced perfusion (DCE-P) to conventional MRI in differentiating benign and malignant non-fatty soft tissue tumors (NFSTT). Researchers prospectively examined a total of 288 patients with NFSTT who had undergone conventional and advanced MRI from November 2009 to August 2017 [there were 104 (36.1%) malignant and 184 (63.9%) benign tumors]. Two additional radiologists (R3 and R4) examined DWI, H-MRS, and DCE-P data of indeterminate tumors. After conventional MRI analysis alone, the prioritized use of advanced MRI techniques allowed to reduce by about 30% the number of non-myxoid NFSTT deemed indeterminate.
