INTRODUCTION: @entity490 in @entity7965 has never been investigated by in-vivo imaging studies. With MRI, we aimed to assess mesenteric vessels flow and small bowel wall perfusion to investigate the ischemic origin of @entity490 . MATERIALS AND METHODS: Six @entity7965 @entity1 with (AP) and six without (NOP) @entity490 underwent MRI. In a blinded fashion, @entity450 (MF, quantity of blood moving through a vessel within a second, in mL  s-1) and @entity64 volume (SV, volume of blood pumped out at each heart contraction, in mL) of Superior Mesenteric Vein (SMV) and Artery (SMA), areas under the curve at 60 (AUC60) and 90 seconds (AUC90) and Ktrans were assessed by two operators. RESULTS: Mean total perfusion and flow parameters were lower in AP than in NOP group. AUC60: 84.81    11.75 vs. 131.73    18.89 (P < 0.001); AUC90: 102.33    14.16 vs. 152.58    22.70 (P < 0.001); Ktrans: 0.0346 min-1    0.0019 vs. 0.0521    0.0015 (P = 0.093 duodenum, 0.009 jejunum/ileum). SMV: @entity59053 .67 ml/s    0.85 vs. 8.32    2.14 (P = 0.002); SV 3.85 ml    0.76 vs. 6.55    1.57 (P = 0.02). SMA: MF 6.95    2.61 vs. 11.2    2.32 (P = 0.07); SV 6.52    2.19 vs. 8.78    1.63 (P = 0.07). We found a significant correlation between MF and SV of SMV and AUC60 (MF:   = 0.88, P < 0.001; SV:    = 0.644, P = 0.024), AUC90 (MF:    = 0.874, P < 0.001; SV:   = 0.774, P = 0.003) and Ktrans (MF:   = 0.734, P = 0.007; SV:   = 0.581, P = 0.047). CONCLUSIONS: Perfusion and flow MRI findings suggest that the @entity1503 supply is significantly associated with @entity490 in @entity7965 .
