Figure 3 Example case of a 63-year-old man with jejunal gastrointestinal bleeding detected at computed tomography angiography and evaluated with a semiautomated software (bleeding rate: 5. 397 mL/min) and not confirmed by catheter angiography (non-concordance group). A: Computed tomography angiography (CTA) in the arterial phase showing jejunal gastrointestinal bleeding (GIB) on axial view; B: CTA in the venous phase showing jejunal GIB on axial view; C: GIB volume evaluation in the arterial phase of axial CTA with a semiautomatic software on a dedicated workstation. Bleeding volume was 0.330 mL; D: GIB volume evaluation in the venous phase of axial CTA with a semiautomatic software. Bleeding volume in the venous phase was 0.769 mL; E: GIB volume evaluation in the arterial phase of coronal CTA; F: GIB volume evaluation in the venous phase of coronal CTA; G: GIB volume evaluation in the arterial phase of sagittal CTA; H: GIB volume evaluation in the arterial phase of sagittal CTA; I: Catheter angiography of superior mesenteric artery showing no signs of bleeding; J-L: Superior mesenteric artery angiograms after multiple selective and super selective catheterisms of distal branches showing no signs of bleeding.
