MRI在肠梗阻诊断中的进展

The progress of MRI in the diagnosis of intestinal obstruction

肠梗阻是常见的疾病,占急腹症的20%,有起病急、进展快、病死率高的特点,故早期诊断肠梗阻对愈后至关重要。常规MRI作为一种简便又无创的检查方法,多种成像技术,如MRI水成像(MRH)、MR胆胰管成像(MRCP)、MR肠道成像(MRE)、MR电影成像(Cine MRI)对肠梗阻的定位及病因诊断均较CT准确,而功能MRI的多种成像序列通过各自成像参数的特点能够反映不同的微观病变,对肠梗阻早期诊断有较高的价值。就MRI应用于诊断肠梗阻的技术及其进展予以综述。

Intestinal obstruction is a common disease, accounting for 20% of the acute abdomen diseases. It has the characteristics of acute onset, rapid progress and high mortality. Early diagnosis of intestinal obstruction is crucial for the recovery. As a simple and noninvasive method, multiple MRI techniques, such as MRH, MRCP, MRE and cine MRI etc, are more accurate than CT in the diagnosis of the location and etiological of intestinal obstruction. However, the functional magnetic resonance imaging through characteristics of each imaging parameters can reflect different microscopic lesions, and has high value for early diagnosis of intestinal obstruction. In this paper, the application of MRI technology in the diagnosis of intestinal obstruction and its new development were reviewed.
