Abstract: Objective To study the relationship between the CT features and pathological grade of malignancy of the gastric stro-mal tumors (GST).Methods A retrospective review was performed based on the database of 80 consecutive patients with GST.Age and gender of the patients were recorded,and the CT findings of GST including growth pattern,morphology,tumor site,boundary, mucosa,serosa,ulcer,volume and maximum diameter of the tumor were also measured.The patients were divided into three groups:very low and low risk group,intermediate risk one and high risk one according to the pathology.All parameters were ana-lyzed by one-way ANOVA or Fisher’s exact test.Results The patients in 3 groups (from low risk to high one)were 30,30 and 20 respectively.There were no significant differences in age,gender,location and mucosa among 3 groups(P>0.05).However,the growth pattern,morphology,boundary,serosa,ulcer,volume and maximum diameter of the tumor were significantly different (P<0.05).Conclusion The CT features including growth pattern,morphology,boundary,serosa,ulcer,volume and maximum diameter of the tumor can be used to evaluate the grades of malignancy in GST.
