Possibility of contrast-free MR-perfusion using in differential diagnosis of soft tissue tumor

Abstract

Contrast-free MR-perfusion of "labeled arterial blood spins" ("ASL-perfusion") is an MR-technology for qualitative and quantitative assessment of tissue perfusion properties based on of arterial blood proton spins labeling by radiofrequency pulses and their subsequent measurement when passing through the area of interest. The most of ASL-perfusion application clinical data referred to central nervous system diseases diagnostics, but some works showing the effectiveness of this technique in assessment of skeletal muscle perfusion and diagnostics of soft tissue tumors appeared recently.Two presented clinical cases (soft tissue tumor and post-traumatic benign changes) demonstrate the possibility of this technique usage to assess vascularization of pathological changes in hip soft tissues.
