Purpose. This study sought to assess the role of multislice computed tomography (MSCT) in patients with suspected chronic mesenteric ischaemia (CMI). Materials and methods. Forty-five patients (29 men; mean age 68) underwent MSCT angiography of the abdomen for suspected CMI (main clinical finding: postprandial abdominal pain). The scan protocol was detectors/collimation 16/0.75 mm; feed 36 mm/s; rotation time 500 ms; increment 0.4 mm; 120-150 mAs and 120 kVp. A volume of 80 ml of contrast material was administered through an antecubital vein (rate 4 ml/s), followed by 40 ml of saline (rate 4 ml/s). Images were analysed on the workstation with different algorithms (axial image scrolling, multiplanar reconstructions, maximum intensity projection, volume rendering). Targeted central lumen-line reconstructions (curved reconstructions) were obtained along the celiac trunk (CeT) and superior mesenteric artery (SMA). Vessel occlusions and significant (>50%) stenosis were recorded. Results. Image generation and interpretation required 25 min. Stenosis and/or occlusions were detected in 29 (65%) cases on the CeT and in 32 (71%) on the SMA. Of those lesions (n=61), 44 (49%) were classified as not significant. In 16 (35%) cases, there was a simultaneous stenosis and/or occlusion of the CeT and SMA (confirmed by conventional angiography). In six (13%) cases, there were no lesions affecting the CeT, SMA or their branches (confirmed by clinical follow-up). Conclusions. MSCT angiography can play a major role in the detection of stenosis of the abdominal arteries in patients with suspected CMI.
