Abstract:Objective: To investigate the role and advantages of 256-slice CT perfusion in displaying blood vessel and muscle-microcirculation of high voltage electrical injured limbs. Methods: Perfusion scanning was performed for both-limbs and trunk by Phillips 256 slice intelligent CT(iCT). All the images were imported to EBW workstation. Images were post-processed, perfusion parameters were calculated and perfusion picture was reconstructed using Functional CT-general mode. Blood vessels were rebuilt using MPR, CPR, VR, MIP and AVA software. Results: All the 21 cases got clear CTA imaging. Stenosis, discontinuity and obstruction of blood vessels were seen in 7 cases. Fourteen cases had normal CTA. Muscle damage was seen in 21 cases. Conclusions: 256 slice iCT perfusion is a safe, convenient and simple examination method. We can obtain the information of blood vessel and muscle-microcirculation from it. It could provide much more and full-scale image data for clinical treatment.
