ABSTRACT
Objective To investigate the diagnostic value of the early slope value of enhancement in differentiating benign from malignant musculoskeletal masses.Methods Dynamic contrast-enhanced gradient-recalled acquisition in the steady state imaging(GRASS) was performed to evaluate 36 musculoskeletal masses(18 malignant,18 benign).The difference of the early slope value of enhancement was analysed and compared between benign lesions and malignant ones.Using ROC curve plotting obtained the best decisive threshold.Spearman rank correlation analysis was used to determine the relation between slope and microvessel density of tumor tissues.Results The average early slope value of enhancement was (4.33?2.70)% per second (range 0.97%~10.50% per second)for malignant lesions,and was (1.46?0.97)% per second(range 0.37%~3.86% per second)for benign ones.There was an apparent statistical significance between benign and malignant tumors(?
