摘要
目的探讨多层螺旋CT在十二指肠间质瘤诊断中的临床应用价值。方法回顾性分析经病理或手术证实的13例十二指肠间质瘤的特征性影像表现,肿瘤增强扫描后动脉期、静脉期及延迟期三期的变化,并结合三维重建技术进行观察。结果本组13例十二指肠间质瘤中,良性肿瘤8例,交界性2例,恶性3例。黏膜下型7例,浆膜下型5例,肌壁间型1例。腔内生长4例,腔外生长6例,腔内外生长3例。13例患者经多层螺旋CT检查病灶均清晰显示。结论多层螺旋CT三期动态增强扫描结合三维重建技术在十二指肠间质瘤诊断中价值较大,能够极大提高病灶检出率,对十二指肠间质瘤的诊断和鉴别诊断具有较高的临床应用价值。
Objective To investigate the clinical value of multi-slice spiral CT in the diagnosis of duodenal stromal tumors. Methods The imaging features of 13 cases of duodenal stromal tumors confirmed by pathology or surgery were retrospectively analyzed. The changes of arterial phase, venous phase and delayed phase after enhanced scanning were observed with three-dimensional reconstruction technique. Results Of the 13 cases of duodenal stromal tumors, 8 were benign, 2 were borderline and 3 were malignant. There were 7 cases of submucosal type, 5 cases of submucosal type and 1 case of intermural type. There were 4 cases of intraluminal growth, 6 cases of extraluminal growth and 3 cases of intraluminal and extraluminal growth. The lesions of 13 patients were clearly displayed by multi-slice spiral CT. Conclusion MSCT three-phase dynamic contrast-enhanced scanning combined with three-dimensional reconstruction technology is of great value in the diagnosis of duodenal stromal tumors, which can greatly improve the detection rate of the lesions, and has high clinical value in the diagnosis and differential diagnosis of duodenal stromal tumors.
