ABSTRACT
Objective To investigate the imaging features of gastrointestinal stromal tumors (GIST) and its diagnostic value. Methods The clinical and imaging data of 41 patients with GIST proved by operation and pathology were analysed. Results Tumors located in the stomach in 20 cases, small bowel in 5 cases, rectum in 3 cases, esophagus in 2 cases and extra gastrointestinal sites in 11 cases. There were 27 malignant GIST diagnosed by imageologic examination,of them, 21 mass exceeded 5 cm in diameter, margins were vague, 19 cases had obvious adhesion or directly involved with around tissue,13 cases with obvious necrosis and cystic changes within the mass. 5 cases with metastase focus.Benign GIST in 14 cases, 11 cases were less than 5 cm in diameter, most of them had smooth margin,homogeneous density and symmetrical enhancement effect.Conclusion X-ray gastrointestinal double contrast radiography examination finds easily inside antrum and inside-and-outside antrum type GIST; CT examination offsets deficiency of general gastrointestinal radiography. It is valuable in localizing precisely, judging benign and malignantin, guiding clinical therapy and estimating prognosis for GIST.
