【Abstract】 Objective To analyse the imagings of gastrointestinal stromal tumors (GIST). Methods In five cases of GIST, small bowel enema in 1 case, gastrointestinal radiograhy in 3 cases, CT examination in 2 cases, utrasonography in 2 cases, gastroscope in 3 cases were performed. Results Through imageologic examinations, GIST of pars carcliaca, corpus ventriculi pariesposterir wall of fundus, jejunum and ileum were discovered respectively. All cases were proved by operation and pathologic examination. Two cases were made immunohistochemical examination: S 100(+), Vim(+), Des(+). One case was CD34(+),PCNA(-),p53(-). Conclusion Coventional X ray examination of gastrointestinal tract, combined with endoscopic examination is still the main method for discovering and diagnosing stromal tumors.
