Full Range of Motion MRI
Feedsee Medical : Full Range of Motion MRI : Visualizing the body in the range of normal positions that generate symptoms
In 2007, MRI Scanning pioneer FONAR sold a Full Range-of-Motion Multi-Position MRI to the Center for Diagnostic Imaging. The ability of its MRI technology to fully visualize all body parts, and particularly the spine, fully weight-loaded and in its full range of normal positions, was a key new capability. The positioning capability of the FONAR scanner permited the MRI operator, with the patient's cooperation, to position the patient in the actual position that engenders his/her symptoms, so that a picture can be taken of the patient's body part in the exact position that generates his/her symptoms. "FONAR's new technology, that enables visualization of full weight-bearing flexion and extension of these key body parts, will add a new dimension of service to CDI's state-of-the-art imaging facility," said Doctor Raymond Damadian.
Advancements in MRI Technology
Magnetic Resonance Imaging (MRI) technology has seen numerous advancements over the years, increasing both the quality and utility of this essential diagnostic tool. Here are some of the improvements that have been made:
- Higher Resolution Imaging: Over the years, MRI technology has improved to produce higher resolution images, providing detailed views of soft tissues and structures within the body. This has led to more accurate diagnosis and treatment planning.
- Speed: Advances in hardware and software have made MRIs faster, reducing the time patients must stay still during the scan, which improves patient comfort and decreases the likelihood of motion-related artifacts in the images.
- 3D Imaging: With 3D imaging technology, MRIs can now create three-dimensional images that can be viewed from different angles, giving doctors a better understanding of the structure and condition of the patient's body.
- Functional MRI (fMRI): This is an advanced form of MRI that measures the small changes in blood flow that occur with brain activity. It may be used to create a map of brain activity and is particularly useful for brain surgeries.
- Diffusion Tensor Imaging (DTI): This is a type of MRI that can identify microscopic details about tissue architecture, providing insight into white matter lesions and tumor infiltration. It is particularly useful in neurology and can help diagnose conditions like Alzheimer's.
- Open MRI: Traditionally, MRIs have been "closed," meaning they are a narrow tube that the patient is moved into. Open MRIs were developed to accommodate patients who experience claustrophobia or who are larger.
- Silent Scan Technology: Modern MRIs have significantly reduced their noise levels, improving patient comfort without compromising image quality.
- MRI-Guided Biopsies and Procedures: Improvements in real-time imaging capabilities have made it possible to use MRI guidance to perform biopsies and certain procedures, increasing their precision.
- AI and Machine Learning: Machine learning algorithms are being developed and implemented to improve image analysis, predict disease progression, and automate time-consuming tasks such as segmentation.
These advancements have not only improved the precision and quality of MRI scans but also increased their applicability to a broader range of medical conditions.
