PURPOSE: Spiral CT angiography (CTA) was performed on 22 patients for the preoperative assessment of epigastric tumors in comparison with intraarterial angiography. METHODS: One hundred fifty milliliters of contrast material was administered with a flow of 4 ml/s. After a delay of 30 s, a spiral CT examination of the epigastrium was performed (slice thickness 3 mm, table feed 6 mm/s). Axial images were reconstructed at 2 mm increments. Postprocessing was performed with a maximum intensity projection and shaded surface display imaging program. Plain film arteriography was performed via a catheter inserted transfemorally and placed into the epigastric arteries. The following parameters were evaluated: visualization of the arteries and the portal vein and involvement of these vessels by disease. RESULTS: The vessels (22/22 = 100%) and variations (1/22 = 4.5%) were clearly identified with both techniques. Involvement was diagnosed by angiography 15 times compared with 22 findings by CTA. CONCLUSION: Concerning vessel anatomy, the correlation between both techniques was excellent and vessel involvement showed good correlation, especially when using the axial slices additionally. CTA has the potential to become a minimally invasive diagnostic tool for preoperative planning in epigastric tumors. |
