Fusion imaging technology (FIT) combines different imaging techniques by means of properly designed software. The aim of this study was to validate the ultrasonographic representation of intracranial vein anatomy by combining transcranial echo-colour Doppler (TECD) with conventional magnetic resonance imaging (MRI). In addition, we investigated the possibility of insonating the veins of the base of the skull through the novel condylar window.
We examined venous brain circulation in five healthy subjects by means of FIT, using a 1.5 T MR scanner and an ultrasound TECD equipped with Virtual Navigator technology. Results and conclusions Insonation of the Rosenthal and other intracranial veins through the classical transtemporal window, based on anatomical assumption, but never before validated by means of FIT study, was confirmed. Moreover, in all five subjects, FIT demonstrated the possibility of insonating the petrosal sinuses and the cavernous sinus area through the novel transcondylar approach. In conclusion, the feasibility of FIT of the intracranial veins potentially permits to study subjects in different postures and/or at the bed of non-transportable patients, after the initial MRI acquisition. Finally, the novel transcondylar approach allows obtaining haemodynamic information from the cavernous and the petrosal sinuses usually not investigated by TECD alone.
融合成像技术（FIT）通过精心设计的软件将不同的成像技术结合起来。本研究的目的是通过将经颅彩色多普勒超声（TECD）与传统磁共振成像（MRI）相结合，验证颅内静脉解剖结构的超声表现。此外，我们研究了通过新型髁窗对颅底静脉进行超声检查的可能性。
我们使用1.5 T MR扫描仪和配备虚拟导航技术的超声TECD，通过FIT对5名健康受试者的脑静脉循环进行了检查。结果与结论通过经典的颞窗对罗森塔尔静脉和其他颅内静脉进行超声检查，基于解剖学假设，但此前从未通过FIT研究进行验证，现已得到证实。此外，在所有5名受试者中，FIT均显示通过新型经髁入路对岩窦和海绵窦区域进行超声检查的可能性。总之，颅内静脉FIT的可行性可能允许在最初的MRI采集后，对处于不同姿势的受试者和/或在不可移动患者的床边进行研究。最后，新型经髁入路能够从海绵窦和岩窦获取通常单独使用TECD无法研究的血流动力学信息。
