目的探讨分析CT影像检查在胃肠道间质瘤临床诊断中的应用价值,同时提升胃肠道间质瘤相关特征在医学领域的认知度。方法 16例患者接受常规CT水平扫描检查,其余4例接受增强检查。在施行增强检查过程中应该在高压注射器的协助下,将150ml碘海醇注射至患者肘静脉处作为对比剂,注射的速度应该保持在3～50ml/s。结果本次20例胃肠道间质瘤患者中有13例划分在恶性肿瘤范围之内,4例划分在交界性范围,剩余3例检查结果呈现良性。所有患者肿瘤发生的部位如下:3例胃肠道外,3例回肠,7例十二指肠,2例空肠,5例胃部。结论选择使用CT影像来进行检查,能够迅速获取患者体内肿瘤位置、性质、形态等信息,而且信息的准确度非常理想。由此可知,CT影像在胃肠道间质瘤患者诊断过程中存在着很高的价值,值得在临床上推广使用。
Objective To investigate the value of CT imaging in the clinical diagnosis of gastrointestinal stromal tumors, and to increase the recognition of relevant features of gastrointestinal stromal tumors in the medical field. Methods Sixteen patients underwent routine CT scans, and the remaining 4 patients underwent enhanced examinations. In the course of performing the enhanced examination, 150 ml of iohexol should be injected into the patient’s elbow vein as a contrast agent with the aid of a high-pressure syringe, and the injection speed should be maintained at 3 to 50 ml/s. Results Of the 20 patients with gastrointestinal stromal tumors, 13 were classified as being within the range of malignant tumors, 4 were classified as borderline, and the remaining 3 were found to be benign. The locations of tumors in all patients were as follows: 3 gastrointestinal tracts, 3 ileums, 7 duodenums, 2 jejunums, and 5 stomachs. Conclusion Selecting CT images for examination can quickly obtain the location, nature, and morphology of the tumor in patients, and the accuracy of the information is very satisfactory. It can be seen that CT imaging has a high value in the diagnosis of gastrointestinal stromal tumors and is worthy of promotion in clinical practice.
