Abstract

Objective: To explore the diagnostic value of 64-row CT for gastrointestinal stromal tumor (GIST) by using the techniques of plain scan, enhancement and post-processing.

Methods: CT findings of 11 cases GIST were analyzed, among which 10 cases underwent CT plain scan and enhanced double stage.1 case only received plain CT scan without enhancement. CT findings were compared with pathological findings.

Results: There were 11 patients in our study group, most of which were gastric stromal tumors (9 cases), while holileum and colorectal stromal tumors were rare (1 case each), with no multiple lesions. All the patients in this group were single. Among the 11 patients, there were 3 low-risk stromal tumors with uniform density and clear boundaries, and the tumor diameter was generally within 4 cm. Among them, 1 patient had calcification in the lesion, which was small and patchy. The lesion enhancement by enhanced scan was relatively uniform, indicating mild to moderate enhancement. There were 3 cases of moderate risk stromal tumor with uneven density and regular morphology, and the diameter was generally no more than 5 cm. The enhanced scan showed moderate enhancement and heterogeneity. There were 5 cases of high-risk stromal tumor. The tumor was generally large, with the maximum diameter up to 20 cm, uneven lesion density, and multiple internal necrosis. Among them, there was 1 case of patchy calcification in the lesion and 1 case of hemorrhage. The accuracy of CT diagnosis and location was 91% consistent with that of intraoperative exploration, and the accuracy of diagnostic results and pathological control was 82%.

Conclusion: Multi-row spiral CT plain scan plus enhanced scan is one of the important methods for the examination of GIST at present. Post-processing technology can clearly show the size, location and blood supply of the lesions, which can determine the benign and malignant lesions, and has an important value for further clinical diagnosis, treatment and prognosis evaluation.
