On the 24th of August MedTechLabs were proud to be among the medical research facilities in Stockholm and Uppsala to host a visit by GE Healthcare Top Management. Their team was happy to see the progress of the world’s first clinical evaluation of the Deep Silicon CT detector technology for photon counting CT here at BioClinicum in Hagastaden.

Peter J Arduini, President and CEO at GE Healthcare later stated:

“I spent time in my early GE HealthCare career working in CT. This week, it was thrilling to be at the epicenter of this exciting innovation, and I look forward to the potential transformation it will create for CT and the benefit for patients worldwide. Photon counting has the promise to further improve the capabilities of traditional CT and increase imaging performance for oncology, cardiology, neurology, and many other clinical CT applications.”


A new centre that brings together current and future expertise and technology in medical imaging. Expectations for the Centre of Imaging Research (CIR) and what it can achieve in terms of research, industry collaboration and clinical application are sky-high. In this article, Daniel Lundqvist, who heads the centre, talks about how the CIR will make its mark in Sweden and internationally.
Daniel Lundqvist formally became director of CIR - Centre for Image Research - in October 2022. The importance of the new centre was marked by the participation of both Karolinska Institutet's President Ole Petter Ottesen and Karolinska University Hospital's CEO Björn Zoëga in the inauguration. Most of the centre is in Karolinska University Hospital's BioClinicum research building, which is also well integrated with KI. MedTechLab's CT lab is now part of the CIR infrastructure. One block away is the Scilifelab, which also conducts research in the field of imaging.

Daniel Lundqvist is a brain researcher at KI and has a passion for medical infrastructure. He explains that the first thoughts of a single imaging centre came more than 20 years ago, and that brain researcher Martin Ingvar, former head of the MR Centre, and Staffan Holmin, physician and research leader at MedTechLabs, were among those who started working on realising the ideas early on. 

The CIR will bring together the best instruments, platforms, and technologies available in medical imaging, and Daniel has started building the centre's structure and initial operations. 

– In addition to the co-location, we have upgraded with the latest in medical imaging technology. But I want to emphasise that as important as it is to have all this great technology in one place, it is equally important to bring together all the experts in the field of imaging so that they can collaborate and learn from each other, Daniel explains. 

By bringing these people together, level four of the BioClinicum also forms a professional community that is unparalleled in the world. The CIR is likely to be attractive to researchers internationally, which will benefit recruitment to research projects linked to the centre. 

One goal of the CIR is to create benefits for users in research, healthcare and industry. The centre makes it possible to devote resources to their common needs, such as a new platform for storing and sharing image data, which would have been difficult for the various users to create on their own.

The activities at CIR will contribute to the translation of research results into clinical activities, known as translational research. This is facilitated by the proximity to Karolinska University Hospital, which is just a stone's throw away with its doctors and patients.

CIR is partly based on imaging facilities that have already existed for a long time at Karolinska Institutet and Solna University Hospital. What is new is that these are being brought together physically. An important reason for establishing the centre was the realisation of how important it is to be able to perform multimodal imaging, i.e., to combine different types of imaging. Today, this is a logistical challenge when facilities are scattered in different locations, and it also puts a strain on patients or research subjects when they must be moved around. Surprisingly rarely, for example, MRI, MEG, PET and CT are combined on the same individual, even though it is often important to obtain a detailed and multifaceted overall picture. The CIR will therefore enable a wide range of imaging of the structure, function, and metabolism of living organs, using the various modalities of technology available and constantly evolving. The diagnosis and study of cancer, cardiovascular diseases and brain imaging are the focus. For example, NatMEG, a national infrastructure for magnetic encephalography that is one of the most advanced in the world, will be part of the centre. 

One of the CIR's strengths is that we have the very latest or even tomorrow's methods that we are evaluating and trying to utilise. Such as the new photon counting CT technology with silicon detectors that is now being validated in MedTechLabs and a new MRI with ultra-high field strength, called 7-tesla, which is available in Huddinge. - We are currently upgrading NatMEG with an improved system for measuring brain activity with a 128-channel system for on-scalp MEG. This is the latest and greatest in the world," says Daniel.

The centre's ability to provide researchers and clinicians with more information about the appearance, function and metabolism of organs can be of great importance for individual patients with severe diseases. Daniel takes epilepsy as an example: 

- In the brain, epileptic seizure activity can begin as an intense activation of a very small cortical region, which then expands over time to involve progressively larger and larger cortical areas. If a patient needs surgery to remove the part of the brain where seizure activity starts, one will naturally want to identify the exact starting point as accurately as possible. With the technology available at CIR and NatMEG, we believe that it will be possible to find the seizure activity’s starting point more accurately and thus the method can also guide the neurosurgeon with greater certainty, says Daniel.

Another exciting area where CIR could play an important role is theranostics, which combines therapy and diagnostics. Theranostics uses a targeted radiopharmaceutical that can identify and diagnose the extent of a cancer, and then treat the cancer either with a therapeutic radiopharmaceutical (or with targeted oncological treatment).  This method successfully improves the effectiveness of cancer treatment while maintaining quality of life. The field is relatively new and rapidly developing. Sweden has an internationally prominent position in the field, and is among the most active countries in Europe, both in the preclinical development of theranostic drugs to translating and participating in clinical theranostic studies and in initiating them. 

Nationally, there are many links to CIR and Daniel is already involved in several Swedish coordination projects where the focus is on sharing and making data available. Internationally, the centre will also be an important Swedish node for various research collaborations, such as the European e-infrastructure for brain research, EBRAINS. Synchronising CIR with EBRAINS will make it easier for CIR's imaging platforms and users to share and use data in European collaborations between researchers, clinicians, and industry. 

- It has taken a while to realise what a great job I have been given and I am both proud and humbled by this assignment. Since I have worked with imaging issues and imaging infrastructure for a long time, I know that it can be challenging and involves a lot of responsibility. But it is so exciting to be involved in creating something that offers new and unique opportunities that will ultimately benefit healthcare and patients. I share this feeling with many others who will work here at CIR, concludes Daniel.
