ABSTRACT
Objective To evaluate the preoperative T staging value of rectal carcinoma by using double contrast-enhanced ultrasonography (DCUS).Methods 71 patients with rectal carcinoma were examined by ultrasound after infusing contrast agent and bolus injection of SonoVue preoperatively.The border,shape and perfusion patterns of the tumor were observed.After surgery,the T staging made by DCUS and perfused contrast-enhanced ultrasonography (PCUS) was compared with final pathologic results respectively.Results The accuracy of PCUS and DCUS in determining the T stage of rectal carcinoma were 71.8%(T1 72.7%%,T250.0%,T374.4%,T476.9%) and 85.9%(T190.9%,T275.0%,T387.1%,T484.6%) respectively.The difference between these two methods was statistically significant (P <0.05).Conclusions DCUS is a new valuable method for T staging of rectal carcinoma with its high accuracy preoperatively.
