MRI magnetic resonance imaging is a safe, non-invasive diagnostic imaging procedure. MRI uses radio waves, a magnet and computer software to obtain two- and three-dimensional (3D) images of the inside of the body.
These images are used for detecting and treating various diseases in their early stages, such as osteoarthritis, stroke and cancer. MRI can detect disease in structures throughout the body including the brain, eyes, heart, breast, neck, shoulders, spine, heart, liver, kidney, spleen, pancreas, and the pelvis and hips. MRI can also provide amazing images of joints in the shoulder, wrist, ankle and foot.
At Allied Diagnostic we scan with a high-field HDx1.5 Tesla (T) magnet. Tesla is a metric unit that is related to the strength of the MRI unit’s magnetic field. Studies show that a 1.5T magnet produces the best images.
How does MRI work?
When the patient is inside the MRI unit’s magnetic field, tiny particles in the body called protons are forced to line up and spin in the same direction. While the protons are aligned, radio waves are sent into the magnetic field. These signals disturb the protons and make them spin in different directions. When the signal is stopped, the protons line up again and release energy. This energy is measured by the surface coils that are positioned around the area of the body being studied. When turned on, the coils are like special antennae that receive the energy. Diseased tissue emits response signals that vary dramatically from those of normal tissue. The knocking or thumping heard inside the magnet is the sound of the coils being turned on and off as they measure the energy from the disturbed protons. The computer then takes these measurements from the coils and constructs cross-sectional and 3D images of the body’s structures.
Allied Diagnostics presents the latest technology High Resolution 0.35T Open MRI, offering a variety of specialty focused services for detailed studies and accurate diagnostic reading. The advanced coil technology of this MRI system, delivers high definition images of, but not limited to, the chest, abdomen, pelvis, the central nervous system and 3D musculoskeletal imaging. This large open scanner has a fast scanning time (shorter scanning time than conventional open MRI’s) and fast post processing data acquisition. This wide open system is particularly suited for claustrophobic, paediatric and obese patients. The basic technology of an open MRI machine is similar to that of a closed-bore MRI. The major difference for the patient is that instead of lying in a narrow tunnel, the imaging table has more space around the body so that the magnet does not completely surround the person being tested, alleviating any feelings of claustrophobia.
