Purpose: The physiological increase of mesenteric blood flow after a meal is impaired in patients with occlusive chronic mesenteric ischemia (CMI). This principle could be used to develop a highly desired diagnostic test assessing the sufficiency of the collateral mesenteric circulation. This study assesses the potential to identify CMI patients using two-dimensional time-resolved phase-contrast magnetic resonance imaging (2D PC-MRI) flow measurements. Method: This prospective cohort study included patients with suspected CMI, based on: typical history, imaging, and functional testing. Cardiac gated 2D PC-MRI flow measurements (expressed as ml/min/kg) were performed in mesenteric arteries and veins during inspiration and expiration, after six hours of fasting and 20, 30, and 40 min after a meal challenge with a high caloric drink. Results: Flow measurements were obtained in 19 patients: 8 CMI and 11 non-CMI. CMI patients showed a significantly smaller increase in postprandial blood flow in the superior mesenteric artery (SMA) at 30 and 40 min (30 min CMI 1.27(0.12–2.44) vs. non-CMI 7.82(6.28–10.90); 40 min CMI 0.30(-0.26–3.16) vs. non-CMI 7.94(6.32–10.90)) and a lower total arterial flow at 40 min (CMI 3.21(-0.72–5.05) vs. non-CMI 9.31(5.58–13.83)). Repeated flow measurements showed normalization of impaired postprandial venous flow after mesenteric artery stenting in one patient. Conclusions: The significantly lower increase in postprandial mesenteric blood flow in CMI patients confirms the promise of mesenteric blood flow measurements, before and 30–40 min after a meal, as a future diagnostic test to identify CMI patients among patients with a high clinical suspicion of CMI and mesenteric artery stenosis.
