壶腹周围癌影像学诊断方法的研究现状与进展

Research status and progress of imaging diagnosis of periampullary carcinoma

目的总结壶腹周围癌影像学诊断方法的研究现状与进展。方法查阅近年来国内外有关壶腹周围癌影像学诊断方法的相关文献并进行综述。结果对于壶腹周围癌,目前常用的影像学诊断方法主要有超声、CT、MRI和内镜下逆行胰胆管造影。此外,一些其他新型影像学技术也被应用于壶腹周围癌的诊断及评估中,如表观弥散系数容积直方图分析、三维可视化技术等。结论不同影像学检查方法对壶腹周围癌的诊断各有优势与不足,因此临床上应合理选择影像学技术或者联合应用多种技术,以提高壶腹周围癌的检出率与诊断准确率。

Objective To summarize the research status and progress of imaging diagnosis of periampullary carcinoma. Methods The literatures on imaging diagnosis of periampullary carcinoma were reviewed. Results At present, the commonly used imaging diagnosis methods for periampullary carcinoma mainly include ultrasound, CT,MRI, and endoscopic retrograde cholangiopancreatography. Some other new imaging techniques had also been applied in the diagnosis and evaluation of periampullary carcinoma. Conclusions Different imaging methods have their own advantages and disadvantages in the diagnosis of periampullary carcinoma. Therefore, the detection rate and diagnostic accuracy of periampullary carcinoma can be improved by rational selection of imaging techniques or combined application of multiple techniques.
