Evaluation of lymphovascular space invasion in endometrial carcinoma by APTw and mDIXON-Quant

Lymphovascular space invasion(LVSI)is one of the important factors for poor prognosis of endometrial carcinoma(EC). Quantitative parameters of amide proton transfer weighted(APTw)and Modified Dixon quantification of fat(mDIXON-Quant) is a novel MRI tool to evaluating LVSI in EC. The APT and R2* values of LVSI(+)EC were higher than those of LVSI(-)EC. APT value was moderately positively correlated with R2* value, and APT value was weakly positively correlated with FF value. Both APTw and Mdixon-Quant techniques can effectively evaluate EC LVSI, and their combined application can improve the evaluation efficiency.
