Abstract Objective: To explore the role of multilayer spiral CT perfusion imaging(MSCTPI) technology in evaluating the survival of covered flap after large-area cranioplasty. Method: Four months after temporal craniectomy, the patients with flap areas about 45 cm2 were enrolled, and MSCTPI was performed after 2 weeks post-cranioplasty. There were 12 cases in flap survival group and 12 cases in flap necrosis group. The data were analyzed by body perfusion software, and the BF, BV and TTP were statistically analyzed. Results: MSCTPI showed that the density of right occipital flaps in the necrotic group reduced, small slices of necrosis could be seen, and a part of flap was absent, the perfusions of right temporal and occipital flaps were low(blue areas); the density of flaps in survival group were in accordance with healthy sides, perfusion pseudo-maps of flap and healthy sides were of the same color, BF and BV of necrosis group reduced in comparison to that of survival group; TTP of necrosis group prolonged in comparison to that of survival group; there are significantly statistical differences in BF, BV and TTP between two groups. Conclusion: MSCTPI technology can quantitatively evaluate the survival of flaps after large-area cranioplasty. It provides a new clinical method to quantitatively evaluate blood supply of flaps.
