Pr. Alban Denys – CHUV Lausanne, Switzerland

“Imactis is used in my centre on a daily basis. It is particularly useful for out-of-plane access to deeply located lesions like adrenal tumors or liver lesions located under the dome. It is extremely user-friendly, easy to manage and simple both for the nurses and technicians in my angio lab and for residents rotating every 3-6 months. It has a great potential in the future for complex treatment planning in ablation procedures.

Pr. Eric de Kerviler – APHP, Saint-Louis Hospital, France

“The holy grail in CT-guided procedures is to be able to reach any target lesion quickly and safely. Imactis’s CT-Navigation™ is a very powerful tool as it allows to plan complex trajectories and determine the entry point of the needle simultaneously. Intra-procedurally, the system is particularly efficient in difficult cases for which a double oblique trajectory is mandatory, even with target near the diaphragm. For every procedure, the system also reduces the number of control scans, and therefore maintains the radiation as low a dose as possible for both patients and radiologists.

Pr. Philipp Wiggermann, University Hospital Regensburg, Germany

“Regarding my experience of needle guiding and navigation systems, Imactis CT-Navigation™ is a useful tool that takes into account radiologist needs for secure needle positioning. I appreciate its quickness of setup, its ease of use and its ergonomy in my daily practice. Imactis CT-Navigation™ is a universal solution for a variety of different intervention cases such as biopsie, tumor ablation, drainage or infiltration.”

Dr. Marco J.L. van Strijen, St. Antonius Hospital, Nieuwegein, The Netherlands

“As an experienced user of different needle guiding and navigation systems including robotic assistance for nearly 10 years I know about the requisites for a good navigation system: quick and easy to use, reliable and accurate all the time. The Imactis system does an excellent job in providing this. With very few training one is capable of using this system quickly in CT guided needle interventions, with intuitive guiding and very few controls. Anyone with the ability to test it for only one procedure will immediately acknowledge the great benefit of this system. And I am convinced this system will take CT guided interventions now and maybe CBCT guided interventions in the near future to a completely different level, with accurate and short procedure times.”

Dr. Else Merete Ebbensgaard, Region Hospital, Holstebro, Denmark

“At the Regionhospital in Holstebro, Denmark, we are using Imactis CT-Navigation™ since April 2015. At that time, we have performed more than 1200 lung interventions and also multiple biopsies of bones, kidneys, liver, adrenal glands and retroperitoneal lymph nodes and abdominal and thoracic drainages. Compared to our prior method we have experienced with CT-Navigation™:
Better precision, we can hit targets as small as 7 mm in lungs
– Quick biopsies
– CT-Navigation™ is less sensitive to patient motion
– The possibility to choose a safer path that can be out of the axial plane
– Fewer complications
All radiologists in Holstebro prefer Imactis CT-Navigation™ when doing CT-biopsies.

Pr. Ivan Bricault – Grenoble Hospital, France

“The Imactis navigation station provides valuable assistance by increasing the accuracy and reducing the number of control scans. It would be difficult for me to imagine completing certain complex interventions (double-oblique trajectories for example) without the safety and comfort provided by the Imactis CT-Navigation™ station. The system’s ease-of-use has also helped less experienced radiologists to become acquainted with CT-guided interventions; these radiologists would have been reluctant to perform procedures without the assistance of navigation.”

Dr. Christian Sengel – Grenoble Hospital, France

“I personally used CT-Navigation™ assistance for over 5 years. I am an interventional radiologist specialized in pelvic and abdominal cancer treatment. For me, the system’s benefits are with percutaneous thermal ablations (radiofrequency, microwave and cryoablation) particularly for both deep and mobile nodules, like nodules in segment 7 (Couinaud). CT-Navigation™ considerably increases your accuracy in the first punctions. This also means reducing the number of CT scan controls, without using fluoroscanner, seeing fewer complications in the trajectory, and delivering treatment with more precision (therefore reducing recurrences). Even though in theory the system does not take internal breathing movements into account, the radiologist can move into the acquired volume dynamically, see the shifting of the image of interest and easily extrapolate to obtain the exact path to the target.

Clinical study CT-NAV I – Increased accuracy and fewer controls

IMACTIS CT-Navigation was successfully validated during a comparative, prospective, randomized clinical study on 120 patients at the Grenoble University Hospital on various procedures (drainage, biopsy, tumor ablation, infiltration, sympathicolysis).

The clinical study shows, that when compared to conventional procedures, the use of IMACTIS leads to:

  • Increased accuracy (gain in distance and angle accuracy higher than 50%)
  • Fewer controls are necessary to reach the target.

Clinical study CT-NAV II

Clinical study CT-NAV II is a multicentric, comparative, prospective and randomized clinical study. It took place in 9 French publics hospitals, more than 450 patients were enrolled.

Aim of this trial is to evaluate the clinical benefit of this navigation system by comparing the results obtained in the navigation-assisted group with those obtained in the conventional group during CT-guided procedures.
Three criterias are used:

  • Safety: Number of AEs that are considered to be major.
  • Efficacy: Number of targets reached
  • Performance: Number of control scans acquired during the needle insertion.
