Bottom Line: We found that the mesenterical involvement of acute pancreatitis patients is common on MRI.The mesenterical involvement has a positive correlation with the MR severity index and the Acute Physiology and Chronic Healthy Evaluation II scoring system.It has been shown that MR can be used to visualize mesenterical involvement, which is a supplementary indicator in evaluating the severity of acute pancreatitis and local and systemic complications.

ABSTRACT
The main point of this paper is to study MRI findings of the normal mesostenium and the involvement of the mesostenium in acute pancreatitis and to discuss the relationship between the involvement of the mesostenium and the severity of acute pancreatitis. In clinical practice, the mesenterical involvement in acute pancreatitis was often observed on MRI in daily works, which was little recorded in the reported studies. We conducted the current study to assess the mesenterical involvement in acute pancreatitis with MRI. We found that the mesenterical involvement of acute pancreatitis patients is common on MRI. The mesenterical involvement has a positive correlation with the MR severity index and the Acute Physiology and Chronic Healthy Evaluation II scoring system. It has been shown that MR can be used to visualize mesenterical involvement, which is a supplementary indicator in evaluating the severity of acute pancreatitis and local and systemic complications.

A 43-year-old female with severe AP. The mesostenium showed edema, thickening, and effusions on a coronal SSFSE T2-weighted image (a), on axial SSFSE T2-weighted image (b), and on axial SSFSE T2-weighted with fat suppression image (c).

fig4: A 43-year-old female with severe AP. The mesostenium showed edema, thickening, and effusions on a coronal SSFSE T2-weighted image (a), on axial SSFSE T2-weighted image (b), and on axial SSFSE T2-weighted with fat suppression image (c).

Mentions: AP involved the mesenterical vessels, which manifested blood-vessel-edge unsharpness, vessel-wall thickening, vessel-lumen expansion, and dilated and tortuous lateral-branch small vessels (Figure 2). There were 133 patients (67.9%) who had mesenterical-vessel involvement. The T1WI did not easily show the mesenterical edema and thickening, but it obviously was shown as linear or patchy high signal that was consistent with the running of the mesenteric vessels on T2WI and T2WI + FS (Figure 3). The effusions were shown as low signal on T1WI, and oval or patchy high signal on T2WI and T2WI + FS (Figure 4). According to the MI scoring system, there were 88 cases (44.9%), 58 cases (29.6%), and 50 cases (25.5%) in Grades I, II, and III, respectively.
