"a volume of 100–120 mL of iodinated contrast medium is administered at a rate of 4-5 mL/sec"
"portal venous phase (obtained 60–70 seconds after contrast agent injection), images in this phase are obtained from above the level of the diaphragm to below the level of the symphysis pubis"
"Advantages "
"Findings "
"for 3D images of the splanchnic veins, coronal images of the portal vein and the proximal portion of SMV with its confluence to the splenic vein 1,3"
"Axial CT images should be evaluated for secondary signs of ischaemia e.g. bowel wall thickening, focal lack of bowel wall enhancement, bowel dilatation, mesenteric fat stranding, ascites, pneumatosis intestinalis, free superior mesenteric or portal venous gas, intraperitoneal gas, solid organ infarction."
Expected headings
"Technique "
"Data acquisition and analysis"
"Image interpretation"
"Advantages "
"Findings "
"Arterial pathology"
"Venous pathology"
"because both the mesenteric arterial and venous systems must be adequately evaluated, arterial and venous phases are obtained"
"two-dimensional (2D) multiplanar images, as well as rendering techniques such as maximum intensity projection (MIP), surface shaded displays (SSD) and volume rendering (VR)"
"Axial CT images should be evaluated for secondary signs of ischaemia e.g. bowel wall thickening, focal lack of bowel wall enhancement, bowel dilatation, mesenteric fat stranding, ascites, pneumatosis intestinalis, free superior mesenteric or portal venous gas, intraperitoneal gas, solid organ infarction."
