How AI Can Support Radiologists

MRI and CT – these methods are widely used when it comes to making a diagnosis, be it for injuries, cancer, but also for diseases of the heart, the central nervous system or the skeleton. And they are more needed than ever: A growing and aging population as well as changing lifestyles are contributing to an increase in chronic diseases such as cardiovascular diseases and cancer, leading to a rising number of diagnostic imaging procedures. Time pressure and workload for radiologists are mounting up. Artificial Intelligence (AI) can support radiology to provide accurate and timely diagnosis for patients.

What does that mean in practice and where is the benefit of AI in radiology for patients? For example, AI can aid clinicians in the detection of lung nodules in asymptomatic patients. AI triage applications can flag suspected pathologies for prioritized reading of cases that may need urgent diagnosis and treatment, e.g. potential intracerebral hemorrhage (ICH) or large vessel occlusions (LVO). ICH and LVO can be associated with stroke.

At Bayer, we can build on a deep understanding across a multitude of diagnostic and therapeutic areas, such as oncology and cardiovascular conditions. We are committed to driving innovation in AI. Our goal at Bayer is to support healthcare professionals at all stages of the patient journey from diagnosis through treatment.
