Abstract:
Objective To investigate the imaging features of gastrointestinal stromal tumors.Methods The clinical and imaging data of 22 patients with gastrointestinal stromal tumors(GIST)proven pathologically were retrospectively analyzed.Results Endophytic masses were displayed in 4 patients,exophytic masses in 19 patients,and exo-and endophytic masses in 3 patients.The images from the gastrointestinal radiography displayed the filling defect mass and the local mucosal fold that was pressed,pushed or even destroyed.The CT imaging showed uniform or inhomogenous tumors with calcification or necrosis and cystic changes.The enhanced CT scanning displayed different enhancements of the lesions and the enhancements were stronger in venous phase than in arterial phase.Ultrasonographical images indicated solid or cystic-solid masses with moderate-or low-level echo.Conclusion The menifestations on the images of gastrointestinal stromal tumors are helpful to diagnose the disease.
