MR Ergometer Pedal

The Lode MR ergometer is a unique ergometer that can be used during MRI examinations, making it possible for the patient to exercise instead of increasing stress with medicine.

Part number: 937901
To Specifications

A unique ergometer for exercise during MRI

The MR ergometer is specifically designed for exercising, inducing stress during MRI examinations. In many diseases, symptoms will only occur during stress, therefore a dynamic evaluation is required. Using an MR ergometer is the most natural form of exercise and triggering stress response during MR examinations.

Compatible with MR scanners of renowned brands

The Lode MR ergometer can be used in combination with MR scanners with various bores and of various brands like GE, Philips, Siemens, United Imaging.

MR Conditional

Lode MR ergometers are MR conditional. This means that under certain conditions, the ergometer can be used safely with MR ergometers up till 3 Tesla without artifacts being visible on the image.

 

Clinical and Research applications

A stress MRI is a tool for both Clinical and the Research purposes. During an at rest MRI scan medical professionals see images, these, however do  not reflect on the complete situation of a patient or test person. In order to evaluate some conditions, a increased heart rate has to be applied to these images in the case of MRI, this is called a Dynamic/Exercise MRI. The goal of the MR Ergometer is for the patients to get a higher heart rate by exercising while being in the MRI.

Clinical

Cardiac magnetic resonance imaging (CMR) is widely accepted for cardiac imaging. The main benefit of MRI over other techniques is that it gives the most accurate information on various features of the heart. The three main clinical applications are cardiology (heart pathology), angiology and sports medicine (training, prevention and evolution).

Research

For scientific research, the use of MRI for the heart (or CMR) is increasingly popular. The Lode MR ergometer is also used in various research fields, like

  • Heart and cardiovascular system
  • Cardiopulmonary system
  • Neurology
  • Musculoskeletal
  • Metabolism

Features

Exercise instead of medicine

When a test subject is able to do exercise, it is always recommended above pharmacologic stress. It allows objective measurement in either level of cardiac conditioning and/or level of cardiac work. The patient achieves his/her maximum heart rate from exercise, it can be stopped at any moment with no risk of prolonged side effects. It is safe and perfectly reproducible.

Better control of maximum heartrate through watt control

By using the innovative Lode Ergometry Manager Software, the radiologist/cardiologist can control the intensity of the exercise and make changes to decrease discomfort and achieve test goal, which is maximum heart rate (85%) and acquire images in a timely and safe manner.

MR conditional

Lode MR ergometers are MR conditional. This means that under certain conditions, the ergometer can be used safely with MR ergometers up till 3 Tesla without artifacts being visible on the image.

Tesla independant

The choice of materials and the special design makes that the Lode MRI ergometer is useable for various Tesla MRIs.

Small adjustment steps

The workload of the Lode ergometers is adjustable in steps of only 1 watt. Depending on your wishes, the test operator or the test subject can adjust the workload. The steps of 1 watt are possible in the manual mode as well as within protocols.

Suitable for various brands and types of MRI scanners

The Lode MR ergometer can be used in combination with MR scanners with various bores and of various brands like GE, Philips, Siemens, United Imaging.

Accurate over a long period of time

The Lode ergometers are supplied with an electro-magnetic braking mechanism of Lanooy (eddy current). The biggest advantage of this braking system compared to a friction braking system is the absolute accuracy and the accuracy over time. Moreover, friction braking systems have more wearing parts.

Worldwide installed base of renowned institutes and users

For more than 20 years, Lode has developed an MR compatible ergometer that has found its way to several hospitals and institutions worldwide.

Scientific publications

The Lode MR ergometer has been used in over 50 research topics, in a.o the Journal of Biomedical Imaging and Bioengineering, Physiological Measurements, Journal of computer assisted tomography and Circ Cardiovasc Imaging

National Heart Centre Singapore

2023

The MR Ergometer Pedal fits well with our set-up and we have been using this as an exercise stress modality since 2017. Our radiographers and patients have excellent feedback on the comfort and ease of use.

At the National Heart Centre Singapore, we have developed an exercise stress CMR protocol using the MR ergometer pedal to differentiate patients with exercise induced cardiac remodeling from early dilated cardiomyopathy; and patients presenting with chest pain and suspected ischemic heart disease.

We developed the exercise CMR stress protocol to increase diagnostic confidence of differentiating patients with exercise-induced cardiac remodeling from early dilated cardiomyopathy and diagnose ischemic heart disease in patients presenting with chest pain.

Medical imaging encompasses different imaging techniques that are used to image the interior human body for diagnostic and treatment purposes, as not all diseases are always visible from the outside. Medical imaging has advanced in remarkable ways since the discovery of X-rays, magnetic resonance imaging and ultrasound, and revolutionized the medical field.

For decades, perhaps even centuries, doctors and researchers have been interested in how the human body works during health, illness, rest and during or after exercise. This has been accomplished in various ways, and consequently, it is only logical that doctors and researchers eventually became interested in scanning the human body during and after exercise.

Most images reflect just a snapshot and do not reveal the entire physiological range of an organ.  Certain symptoms of cardiovascular disease only occur with stress, and measures of cardiovascular fitness require testing of limits of performance. Therefore, a dynamic evaluation is required to get more accurate results.

Magnetic resonance imaging (MRI) is a technique that was discovered more than half a century ago and since the early 1980s MRI scanners are installed in hospitals worldwide. There has been an increasing demand to combine this imaging method with stress responses. Lode has introduced a suitable solution for this, eliminating the need for Dobutamine to induce stress. There are certain advantages to exercising and imaging simultaneously. These benefits do not only apply to cardiology and muscular research, but other applications could benefit as well.

For over two decades, Lode has pioneered the development of an MR-compatible ergometer, successfully implementing this technology in numerous hospitals around the globe.

Frequently asked questions

Is it possible to use the MRI ergometer with all brands of MRI scanners?

The MRI ergometer is designed to be used with Siemens, GE and Philips MRI scanners. The type of movement (up-down, push-pull or circular) is depending on the diameter of the scanner and the kind of research (cardiac, spectroscopy etc)

Can Lode MR ergometers be used in combination with MRI scanners of 3 Tesla

Yes, since January 2010 all Lode MRI ergometers are designed to be used MRI scanners up to 3 Tesla

Is Lode recommending special disinfection procedures for the Lode products due to COVID-19?

Yes, Due to the fact that the scientific research on the spread of Covid-19 is not yet conclusive Lode recommends to disinfect and clean all Lode products and their accessories (cuffs, heart rate belts, SpO2 sensors, handgrips/rails, touchscreens etc) that are in contact with the patient and or the medical personnel with a standard disinfectant as used in the hospital before and after every patient, with attention and care!

Since these agents are sometimes aggressive it might be advisable to check the effect on sensitive surfaces, like cushioning on non-visible areas. Lode will not take responsibility for discoloration due to these agents.

Is the Lode MR ergometer MR safe and / or MR conditional?

Lode MR ergometers are MR conditional. This means that the ergometer can be used safely in the MR room under certain conditions without artifacts being visible on the image. The minimum distance to the bore is the determining factor here.
