- W2379953974 abstract "Objective: To evaluate the technique and application value of multi-slice spiral CT perfusion imaging preliminarily. Methods: Ten New Zealand white rabbits weighted 1.6～1.8kg were implanted with 0.2ml VX2 tumor tissue suspension in the left or right proximal thigh. Fourteen days later, CT plain scan and perfusion scan were performed on these rabbits respectively by GE lightspeedTM 4.X MSCT scanner, then the images were transmitted to AW4.0 workstation, the functional maps and perfusion parameters including blood flow(BF), blood volume(BV), mean transit time(MTT) and permeability surface(PS) were computed and analyzed. Subsequently, the rabbits were sacrificed and the tumors of which were taken out for normal optical microscopy examination. Results: All the values of BF, BV, PS of rabbits VX2 tumors were obviously higher while the MTT values were lower than that of the normal muscular tissues significantly(P0.001). Conclusion: MSCT perfusion imaging is an accurate and relatively simple functional imaging technique which can give a quantitative assessment to blood perfusion of tumors, moreover, it can provide important referring basis for making a plan of treatment, monitoring effects after therapy and estimating prognosis." @default.
