In this episode, we explore the fascinating world of in silico trials—a cutting-edge approach that could revolutionize how new medical technologies are tested and approved. Imagine conducting clinical trials entirely within a computer simulation, bypassing the need for expensive and time-consuming real-world testing. This futuristic-sounding method is already being utilized today, offering a glimpse into the future of healthcare.
We delve into a groundbreaking study that leveraged in silico trials to test a new breast cancer screening technology called Digital Breast Tomosynthesis (DBT). Unlike traditional mammograms, DBT provides a detailed 3D image of breast tissue, potentially improving early detection of cancer. By creating virtual patients and using advanced computer models, researchers simulated the effectiveness of DBT, achieving results that aligned with real-world clinical trials.
Join us as we discuss the implications of this technology not only for imaging but for drug development and personalized medicine. Could this be the end of traditional clinical trials? While in silico trials show immense potential, challenges remain, and real-world testing will still play a crucial role. Nevertheless, this innovative approach represents a significant step towards a more efficient and safer future in medical research and treatment.

Ever wondered if your brain has the ability to heal itself? In this episode, we delve into a medical mystery that feels like science fiction: the phenomenon of spontaneous thrombosis, where brain aneurysms may naturally seal themselves off. Discover how researchers are using advanced computer modelling with virtual patients to explore this incredible process.
We explain the basics of aneurysms, likening them to weak spots in a garden hose, and explore how size and shape affect their ability to self-heal. Larger and taller aneurysms are more prone to clotting due to slower blood flow, much like a still pond versus a rushing river.
Intriguingly, high blood pressure might actually hinder this self-repair process by creating turbulent blood flow. Through a detailed study of a virtual patient's aneurysm, researchers found that high blood pressure increases the shear rate, making clot formation less likely.
Join us as we explore the potential for leveraging the brain's natural healing abilities to treat aneurysms, moving towards a future where treatment is less invasive and more aligned with the body's innate capabilities. This research opens the door to personalized medicine and new hope for medical breakthroughs.
