The Value of Ultrasonography in the Diagnosis of Gastrointestinal Stromal Tumors

Objective:To analyze the value of ultrasonography in the diagnosis of gastrointestinal stromal tumors (GIST). Methods:The sonographic characterization of 83 GIST patients confirmed by pathology were analyzed retrospectively and compared with CT results. Results:In 83 GIST patlents, the final diagnosis included benign (n=6), borderline (n=16) and malignant (n=61). The accuracy of ultrasonography in the diagnosis of GISTs was 82.5% in stomach, 50.0% in duodenum and 45.5% in intestine respectively. The size and the internal echogenicity were critical in differentiating benign and malignant GISTs. There was no statistical difference of diagnostic accuracy between ultrasonography and CT in the diagnosis of GISTs. Conclusion:Ultrasonography is valuable in the diagnosis of GISTs, which is helpful in clinical management.
