Abstract：Objective To investigate the value of spectral computed tomography ( CT) volume shuttle scanning technique in assessment of hemodynamic changes and vascular status before and after superficial temporal artery -middle cerebral artery ( STA-MCA) bypass in the moyamoya disease .Methods Spectral CT volume shuttle scanning technique was performed in 15 patients with moyamoya disease before and after surgery .Preoperative and postoperative whole-brain perfusion images and four dimensional CT angiography (4D-CTA) images reconstructed from perfusion source data were obtained in all patients .In addition, Alberta Stroke Program Early CT Score ( ASPECTS ) was used to offer rapid semi-quantitative evaluation of the hemodynamic changes . Paired t test was applied to assess the difference of the CT perfusion values .Results The bypass arteries of 15 patients were all demonstrated by the four computed tomography angiography (4D-CTA).The preoperative and postoperative values of the CBV , TTP, ASPECTS as well as the preoperative TTP on the potential surgical side and contralateral side were significantly different ( P <0.05).Conclusion Spectral CT volume shuttle scanning technique has great values for the preoperative and postoperative assessment .
