摘　　要：Soft tissue masses deep in the extremities pose significant challenges due to their potential involvement with adjacent major vessels,impacting treatment decisions and prognostication.While MRI is valuable in diagnosing these masses,specific signs for differential diagnosis are lacking.This study focuses on the utilization of mDixon magnetic resonance angiography(mDixon-MRA)combined with compressed sensing(CS)to assess the involvement of adjacent major blood vessels by soft tissue masses deep in the extremities.The methodology involves preoperative imaging evaluation,including conventional MRI and mdixon-MRA,intraoperative observation,and statistical analysis.The study suggests that combining mDixon-MRA with conventional MRI findings improves diagnostic efficacy.Combining mDixon-MRA with conventional MRI enhances diagnostic accuracy,offering clinicians a reliable method for assessing vascular involvement in soft tissue masses,thereby improving patient outcomes.
