Our MRI machine is an “open bore” machine. An “open bore” machine has a larger opening than traditional MRI machines, making it easier for patients who may be claustrophobic. Our MRI machine is a 3T magnet machine, compared to a typical machine that is around 1.5T. When comparing MRI machines, it is important to understand what the T stands for. Teslas (T) measures the strength of the magnetic field. The 3T MRI machine at the Joint & Spine Center is the only MRI machine with such a strong magnetic field that we have available in The Christ Hospital Network. The 3T machine allows for a faster exam time for patients, provides the physicians with a more detailed image, and works very well with imaging of small joints.
