Objective To evaluate clinical value of double contrast-enhanced ultrasonography(DCUS)in diagnosing gastric stromal tumors(GST). Methods The medical records of 26 patients with a histological diagnosis of GST were retrospectively reviewed. The correlation between DCUS features and pathological findings of the lesions was compared. Results Total 26 cases of GST were divided into low risk group( 16 cases) and high risk group (10 cases). The size,contour,liquefactive necrosis and enhancement distribution of lesions were markedly correlated with the pathobiologic behaviour of the tumor ( P <0.05). There was no significant difference in border and metastasis of lesions between two groups( P >0.05). It was shown that DCUS supplied statistically significant improvement in the localization diagnosis and detection of liquefactive necrosis versus oral contrast-enhanced ultrasonography ( P < 0.05 ). Conclusions DCUS is considered as a valuable tool in diagnosing location as well as pathobiological behaviour of GST. It can provide the guidance and reference comments for treatment algorithms.
