To evaluate the diagnosis value of 16SCT scans in intestinal Hemorrhage.

26 patients with clinic suspected intestinal hemorrhage were included. The patients were performed plan scans first(Lightspeed16,GE). Distension of the intestine was achieved by intravenous administration of anisodamine and effervescent granules 15 min before the scans.Catheter method (4 cases) and peripheral venous method (22 cases) were used differently. In the catheter method, contrast medium (the mixture of Utravist（300 mg I/ml）and saline, ratio: 1:1, 40ml) were injected into SMA @3ml/s. In the peripheral venous method, Utravist（300 mg I/ml）80ml were injected into elbow veins @3ml/s.After enhancement, scanning was performed in the arterial and venous phase. In the Catheter method, the delay time was 2s and 32s. While in the peripheral venous method, the delay time was 30s and 60s. The CA, PV, IVA and their branches to 3D vessel analysis were reformatted by VR, MIP and MPVR reformat. Combined the sources and the thin reconstructed images, the locations and causes of intestinal Hemorrhage were shown clearly. Compared the CT scans results with operations, pathological sections and DSA were performed.

23 patients were confirmed hemorrhage. In the 23 cases, 6 of them were performed the DSA: 5 positives, 1 negative. 3 of them without hemorrhage were found by MSCT (positive rate was 88.5%). MSCT displayed hemorrhage locations: dodecadactylon hemorrhages 12 cases, jejunal hemorrhages 8 cases, ileal hemorrhages 9 cases. Hemorrhage causes were displayed by MSCT: vascular malformation 3 cases, diverticulum 3 cases, ulcer 1 case, cancer 6 cases, cancer companion intussusception 2 cases, inflammation and injury 6 cases, crohn’s disease 2 cases. 18 patients were confirmed hemorrhage by operations, pathological sections or endoscope. 4 patients with inflammatory hemorrhages coped with internal medicine. One dodecadactylon hemorrhage caused by metastatic tumor discharged.

16SCT double phrase enhanced and reconstructed technique is valuable for evaluate the intestinal hemorrhage. It can conduct the operation and clinic therapy.
