Understanding MR Ergometry: Bridging medicine and physical activity

Medical imaging is a cornerstone of modern healthcare, utilizing diverse techniques to explore the inner workings of the human body, aiding doctors in comprehending and addressing illnesses. Some health issues remain hidden from external observation, prompting the use of advanced technologies The continual advancement of X-rays, magnetic resonance imaging, and ultrasound has significantly refined medical imaging, transforming the landscape of healthcare.

Throughout history, healthcare professionals and researchers have tried to grasp the functioning of the human body in various states—health, illness, rest, and exercise. Their goal is to study the body’s responses during and after physical activity. Conventional medical images provide mere glimpses, failing to capture the full spectrum of bodily functions. Certain health problems or irregularities, like specific heart issues, only manifest during activity. Therefore, it becomes paramount to assess performance limits and adopt a dynamic approach to pinpoint these irregularities.

Magnetic resonance imaging (MRI) has been a global presence in hospitals since the early 1980s. The integration of exercise and imaging offers multifaceted advantages, extending beyond the examination of the heart and muscles to various other medical applications.

For over two decades, Lode has been a trailblazer in developing ergometers compatible with MRIs. Widely adopted in hospitals across the globe, these ergometers provide invaluable insights into the intricate relationship between exercise and imaging.
