摘要
目的 对我院收治的1例结直肠癌患者术前使用多层螺旋CT联合MRI诊断判断患者分期中的应用效果。方法 观察了1例患者通过多层螺旋CT联合MRI的影像学检查协助发现和诊断结直肠癌。结果 对此例患者采取多层螺旋CT联合MRI诊断，能够提高T分期诊断正确率及灵敏度、特异度。同时也能够提供更加全面和准确的影像学信息。结论 针对于结直肠癌患者而言，通过多层螺旋CT与MRI联合诊断的方式，可以掌握患者的疾病分期，掌握患者的疾病诊断，为患者提供更为全面且准确度较高的影像学内容，使得结直肠癌诊断的准确率以及特异度得到提升，整体收到的效果更佳，适合广泛推广及应用。

Abstract
Objective To investigate the application effect of multi-slice spiral CT combined with MRI in the diagnosis and staging of a patient with colorectal cancer admitted to our hospital before surgery. Methods A patient was observed to be assisted in the discovery and diagnosis of colorectal cancer by multi-slice spiral CT combined with MRI imaging examination. Results Multi-slice spiral CT combined with MRI diagnosis for this patient can improve the accuracy, sensitivity and specificity of T staging diagnosis. At the same time, it can also provide more comprehensive and accurate imaging information. Conclusion For patients with colorectal cancer, the combined diagnosis of multi-slice spiral CT and MRI can grasp the disease staging and diagnosis of the patient, provide patients with more comprehensive and accurate imaging content, improve the accuracy and specificity of colorectal cancer diagnosis, and achieve better overall results, which is suitable for wide promotion and application.
Key words： Multi-slice spiral CT; MRI; Colorectal cancer; Preoperative diagnosis; Staging; Application value
