Abstract:
Objective To analyze the clinical application value of cinematic rendering(CR)reconstruction technology in acute aortic dissection(AAD),and to compare the imaging quality between CR and volume rendering(VR)reconstruction.Methods Patients with suspected A AD who underwent aortic computed tomography angiography(CTA)were analyzed retrospectively.All images were uploaded to Siemens Syngo.via post-processing workstation for VR and CR three-dimensional reconstruction,respectively.The optimized view angle,staining and transparency were selected and segmented by a radiologist to display the lesion to the full extent.All subjective evaluations of post-processing images were randomly evaluated on Siemens Syngo.via post-processing workstation by two radiologists.The two radiologists reached a consensus after consultation,and the results without consensus were evaluated by another senior radiologist.The 3-point scale was used in the subjective evaluation of post-processing images.The scores of rupture,endometrium,and true and false cavity were recorded.The diagnostic confidence was also recorded.Results A total of 21 ADD patients were enrolled,11 patients(52.3％)were Debakey Ⅲ type.The scores of rupture in CR and VR reconstruction were 2.952 points and 2.619 points,respectively,which had significant difference(P=0.016).For the endometrium of AAD,the score of all 21 patients in the CR reconstruction was 3 points,while only 7 patients(33.3％)in the VR reconstruction had 3 points,which showed significant difference between the both(P＜0.001).For the true and false cavity of AAD,only 1 patient(4.8％)in the VR reconstruction was 3 points,while all 21 patients in the CR reconstruction had 3 points(P＜0.001).The scores of CR reconstruction on the diagnostic confidence were significantly higher than those of VR reconstruction(P＜0.001).Conclusion CR reconstruction can provide photorealistic anatomical post-processing images,and can improve the display and evaluation of AAD.
