Background: There currently is no consensus on the performance of Vessel wall MRI (VW MRI) with carotid webs (CaWs). No clear data exist on compare the performance of each diagnostic features in CaWs.Purpose: To set a standards about the diagnostic features and compare the performance of each diagnostic features in CaWs.Materials and methods : All patients (n = 165, median age, 56.9 ± 13.3) who has done both neck CTA and VW MRI in our radiology department, Zhongnan hospital, performed from February 2017 to April 2019 were included. All CTA and VW MRI images were read by two experienced radiologists.Interobserver agreement for the two reader's decision of CTA was checked by using kappa statistics.Sensitivity, specificity, and area under the curve (AUC) of each diagnostic features at CTA and VW MRI were compared.Results: 10 patients with carotid web was found. The feature "double lumen sign" of CTA and "valve sign" and "contrast stasis" of VW MRI showed good specificity (specificity, 98.6% vs 92.9% vs 93.6%, respectively; P<0.001). The feature "double lumen sign" of VW MRI compared to it of CTA showed higher sensitivity (sensitivity, 80.0% [8 of 10] vs 50.0% [5 of 10], respectively; P<0.001) and better diagnostic performances (area under the curve [AUC], 0.93 [95% CI: 0.68, 0.97] and 0.74 [95% CI: 0.54, 0.94], respectively; P<0.001).Conclusion: The feature "double lumen sign" and "a line or septum" of CTA and "valve sign" and "contrast stasis" of VW MRI may be a crucial performance of carotid web.

There are some problems in the design of three-dimensional visualization teaching resources, such as less involved in interactive design, no unified design standards, the lack of effective innovation guidance mechanism and no unified evaluation system. Based on the design principle, taking amino acids as an example, this paper proposes a design plan for 3D visualization resources in teaching scenarios. According to the design scheme, the three-dimensional visualization resources are made. The main processes include the selection of the tools, the preparation and production of the material, the writing of the script, the design of the learning interface, the design of the interactive logic relationship and the control and output of the program. Finally, the three-dimensional visualization resources are used in the future classrooms with starC electronic double board and group touch screen, and the results are analyzed and evaluated. It is found that the three-dimensional visualization resources can effectively improve the students' interest in learning and help students understand knowledge.
