AIM
To evaluate the usefulness of real-time virtual sonography (RVS) in biliary and pancreatic diseases.
METHODS
This study included 15 patients with biliary and pancreatic diseases. RVS can be used to observe an ultrasound image in real time by merging the ultrasound image with a multiplanar reconstruction computed tomography (CT) image, using pre-scanned CT volume data. The ultrasound used was EUB-8500 with a convex probe EUP-C514. The RVS images were evaluated based on 3 levels, namely, excellent, good and poor, by the displacement in position.
RESULTS
By combining the objectivity of CT with free scanning using RVS, it was possible to easily interpret the relationship between lesions and the surrounding organs as well as the position of vascular structures. The resulting evaluation levels of the RVS images were 12 excellent (pancreatic cancer, bile duct cancer, cholecystolithiasis and cholangiocellular carcinoma) and 3 good (pancreatic cancer and gallbladder cancer). Compared with conventional B-mode ultrasonography and CT, RVS images achieved a rate of 80% superior visualization and 20% better visualization.
CONCLUSION
RVS has potential usefulness in objective visualization and diagnosis in the field of biliary and pancreatic diseases.
目的
评价实时虚拟超声（RVS）在肝胆胰疾病中的应用价值。
方法
本研究纳入 15 例肝胆胰疾病患者。RVS 可通过将超声图像与预先扫描的 CT 容积数据融合的多平面重建 CT（CT）图像，实时观察超声图像。使用的超声仪器为 EUB-8500 凸阵探头 EUP-C514。通过位置移动，将 RVS 图像的评估分为 3 个等级，即优秀、良好和差。
结果
通过将 CT 的客观性与 RVS 的自由扫描相结合，能够轻松解读病变与周围器官之间的关系以及血管结构的位置。RVS 图像的评估等级为 12 个优秀（胰腺癌、胆管癌、胆囊结石和胆管细胞癌）和 3 个良好（胰腺癌和胆囊癌）。与常规 B 型超声和 CT 相比，RVS 图像的可视化效果提高了 80%，更好的可视化效果提高了 20%。
结论
RVS 在肝胆胰疾病领域的客观可视化和诊断方面具有潜在的应用价值。
