目的探讨MR动态增强扫描在上 腹部疾病诊断中的应用价值。方法 选 择我院2012年2月至2014年9月收治的80 例上腹部病变患者，对其进行回顾性分 析。结果 在54例恶性病变中，增强显 示，26(32.5%)例患者的强度曲线为A型， 9(11.25%)例患者为C型，27(22.75%)例 患者为D型。在26例良性病变患者中， 5(6.25%)例患者为B型，13(16.25%)例患 者为D型。以4表格表确切概率法进行分 析，与MRI平扫+普通增强相比，MRI平扫 +动态增强检查方式的准确性更优，差异 有统计学意义(χ2=5.392，P<0.05)。结 论 MRI动态增强检测方式不仅可以显示肿 块的形态学特点，而且有助其良恶性的鉴 别，对病变的定性、边界显示具有更大的 优势。它可以直接反映病灶的血供情况， 因而能够获得与病理学相近的资料。

Objective To investigate the Value of dynamic contrast-enhanced MR scan in the diagnosis of abdominal diseases. Methods 80 patients with abdominal diseases were chosen in our hospital to receive treatment from February 2012 to September 2014. It was treated with retrospective analysis. Results To retrospectively analyze 54 patients with malignant lesions and their enhanced display, 26 (32.5%) patients were the intensity curve of type A, 9 (11.25%) patients had type C, 27 (22.75%) patients were type D. In 26 cases of patients with benign lesions, 5 (6.25%) patients had type B, 13 (16.25%) patients, the D-type. 4 TABLES Table exact test were analyzed, and MRI dynamic enhanced scan compared to the ordinary one, the former had a better accuracy, the difference was statistically significant (χ2 =5.392, P <0.05). Conclusion Dynamic contrast-enhanced MRI detection method can not only show morphological features of mass lesions, can identify benign abdominal mass, malignant lesion characterization, significantly better demarcation of the border. It is directly able to show blood supply of the lesion, and furthermore can obtain Pathology information similar.
