size of course – is that you can have different layouts. You can choose if you want to see the PACS screen, vital signs, prior runs, or the syngo Workplace. So when somebody reconstructs additional information outside the IR room, the radiologist does not have to leave this room in order to look at the images. It is much more intuitive to bring the information into the IR room. We really appreciate this and we fought hard to get the large display. How can Siemens best keep supporting you? The most important thing is that you continue listening to us and working with us. Interventional radiology is one of the most exciting and interesting specialties in medicine. We continue to evolve, but technical innovation is very hard to justify just in itself, what we really need is support for multi-center studies showing the full benefit of IR technologies for the patient. So the role of Siemens is more than just selling machines. It also lies in supporting the work of the institutions and bringing them together for multi-center trials that bring the field forward. Contact simone.henrichs@siemens.com Beyond dose reduction, what differences do you see between Artis Q and former generations of angiographic systems? I have worked with Artis systems before in Berlin and Baltimore, and one major difference is the increased speed of 3D acquisition. syngo DynaCT used to take eight or ten seconds but now you can get high image quality in a five second run, or sometimes in even less than five seconds – and that of course reduces breathing artifacts and movement artifacts significantly. The faster syngo DynaCT really is a main benefit. When do you use syngo DynaCT? syngo DynaCT is a milestone technology. You can use it whenever you need 3D information. I could give you numerous cases where it really improved our work. Maybe the most intuitive example would be a TACE procedure. When a patient comes for the first TACE, we do a single DynaCT run in the arterial phase and sometimes also a portal venous run. This gives us a good overview of the vessel anatomy. We see the tumor feeders and we find out if there are other arteries that go to the stomach or to the phrenic arteries. We can also identify the left and the right gastric artery, which is important when you plan selective internal radiation therapy (SIRT). With a single five second run you get a map of the arteries in good quality and with reduced motion artifacts. This helps in the initial therapy, but also when the patient comes back. You use a lot of different materials in the interventional suite. Are there any devices or tools you can see better with the new system? Our general impression is that the contrast between the surrounding tissue and the guide wire is improved for smaller guide wires and microcatheters. Especially in runoff vessels we use very thin, low-profile material such as 0.014 inch wires. So the higher contrast is of great help in our daily work. What other applications do you consider beneficial in your new Artis Q system? First, I simply have to repeat that syngo DynaCT is a milestone technology, which is, however, still underutilized in IR. Everybody in the IR community who finds it useful should emphasize the benefit because I really think it is of enormous value for the patients. But there are also other applications that are extremely helpful. syngo iPilot, for example, enables overlays of prior information from PET•CT, CT, or MRI. This helps you understand or treat better because you actually have the information where you need it – in the IR room. This is especially important when you have detected a tumor or a bleeder with CT. In times like today, where everybody uses smartphones and where we talk about augmented reality, syngo iPilot simply is a logical step. Finally, there is syngo iGuide. I think needle guidance is very interesting for institutions that do not have enough CT capacity. For some interventions, syngo iGuide is a great help because instead of using CT guidance it allows you to do the puncture in the angio suite. For double oblique approaches syngo iGuide might even be faster than conventional CT guidance. Can you give a concrete example of this? There are applications such as endoleak therapy where you want to do a percutaneous puncture, like a direct aneurysm puncture, and then an embolization of the endoleak. Normally you had to make a compromise. You could use the angio suite – but there you would lack the perfect targeting tool for the percutaneous puncture. Or you had to perform the procedure in CT, where you could actually target the endoleak – but then the embolization would be much more difficult. The solution is an angio suite with syngo DynaCT because you can do the puncture with syngo iGuide and then perform the embolization using fluoro and DSA. You often spend a long time looking at the display during interventions. How important is the large display of the Artis Q system for you? During the intervention, information is everything.
