Key AI trends like informed decision making, integrated diagnostics, and digital twins*, focus very much on how radiology plays a major role in the digital transformation of healthcare and how radiologists and clinicians can be empowered to make the right decision for every patient. AI holds a vast amount of potential to transform aspects of the healthcare industry, and is not something to fear, rather it is something to embrace.Find out how AI in radiology can enable you to respond to the growing demands for your diagnostic imaging services, address potential staff shortages, and enhance your overall imaging workflow.
How do neural networks work in medical imaging?
Neural networks do not work differently in medical imaging than in any other discipline. They just have specific tasks to fulfill that are quite different. That is also the first thing to think about: What task should the algorithm solve and what network structure will be most efficient for this task?
Neural networks are inspired by the brain. As within the brain, they consist of multiple layers. The input layer receives the data (such as a CT volume), while hidden layers extract characteristic data features, which are relevant for the specific diagnostic task and vary between various medical fields of application. In a next step, the detection and expression of the features is being learned by the network to assess them and assign respective interpretation. To train this neural network, a large amount of data is needed to learn, for example, how to differentiate a lung nodule from a healthy lung. For the accuracy of the algorithm, it is important to have a good quality of the data to feed the algorithm, so for supervised learning for example, annotated data is needed.
To ensure the high quality of our algorithms, we collaborate with well-known institutions around the world to understand customer needs to train our algorithms accordingly.
How is AI shaping Radiology?
Artificial intelligence holds significant promise for radiology and is already starting to revolutionize healthcare in many ways. From bridging the gap between the demands of ever-increasing, extremely complex data and the number of radiologists, to simplifying data interpretation through sophisticated AI algorithms and thereby improving the diagnostic process. AI is a valuable tool that, when combined with the human expertise of radiologists and clinicians, offers vast potential to the healthcare industry.
Steadily increasing workload of radiologists
One of the most pressing concerns in radiology today is the exponential growth of data from increase in radiology examinations and the shortage of medical staff to handle it. In many countries, the number of radiology examinations is skyrocketing, while the number of radiologists and imaging specialists is not keeping up with the trend. The result is a dramatically increased workload for radiologists.1
How can AI revolutionize clinical workflows?
In medicine, AI is
sometimes perceived as a new medical device. It isn't. AI is an enabling
technology that allows medical care to be redesigned and improved throughout
the care continuum, from prevention to aftercare.
How do we leverage AI to revolutionize radiology?
Siemens Healthineers CEO Dr. Bernd Montag explains it through a “step-by-step” approach. The first step is to begin with building more and more digitalization into our devices and incorporating AI. As the systems become more intelligent and adapt to patients, they deliver the right quality automatically. The next step is to support diagnostic findings, for example, data from a CT or MR. This is then followed by solving an even bigger challenge, which is to bring all the data from various sources together and build a digital assistant for holistic decision-making in healthcare. It is not a sudden transformation, rather a work-in constant progress.
AI is already used in the workflow, image acquisition and reconstruction space. With the help of AI, we are able to get more accurate data, important for later diagnosis. A great example for this is myExam Companion with features like the 3D camera. With an AI-based algorithm, it analyzes the patient shape and identifies key anatomic landmarks for patient pose, body region, and iso-center detection. Such AI-powered systems not only have the potential to reduce errors due to operator dependency, standardize the acquisitions in a patient specific manner, and cut down the time but can also contribute to radiation dose reduction due to automatic table-height and scan range determination. With the rapid advances of AI also in the field of diagnosis, it is very likely that AI will be used as an additional diagnosis help for examinations and reporting. This is already done today with the intelligent solution AI-Rad Companion3.
What does AI-powered workflow look like?
AI-powered applications have the potential to enhance every step of the imaging workflow and here’s how:
- Order/Schedule: AI-powered connection of patients and physicians
- Preparation and Acquisition: AI-powered standardized, accurate patient positioning and planning of exams
- Postprocessing/Quantification: AI-powered automatic lesion scoring, automatic measurements
- Interpretation/Report Generation: AI-powered automatic highlighting, characterization and quantification of anatomies and abnormalities

What is the road to success for the integration of AI into clinical routine?
Healthcare is one of the most innovative fields in our society and radiology holds huge potential for new AI-powered solutions. But every innovation is only as good as its adoption into the daily routine. For healthcare, it means the new solutions need to be integrated in the clinical workflow and be financially viable. To ensure that our solutions integrate seamlessly in the clinical workflow, we work closely together with our clinical collaboration partners from the very start of new developments and with our continuous improvement and update strategy, we can react quickly on customer feedback.
However, there are other aspects like country regulations and reimbursements that are relevant for getting these innovations into the clinical routine. Siemens Healthineers works closely with clinicians, regulators, and organizations all over the world to standardize our products to the healthcare needs, to provide the best possible outcome in the radiology workflow. At the heart of developing AI products for us lies the focus to help clinicians and radiologists with their daily work to provide better patient outcomes. While we strive to digitalize healthcare, one aspect of this transformation is Artificial Intelligence, co-developed with our customers. Because only when the developed algorithms fit the needs of our customers and follow all rules of the regulators, can we get to the adoption rate where new technology can make a difference.
