MRI - Magnetic Resonance Imaging (General Practice)

Magnetic Resonance Imaging (MRI) is a non-invasive medical imaging technique that uses strong magnetic fields and radio waves to produce detailed images of the body's internal structures. It is widely used in medical diagnosis and research to detect abnormalities and diseases in various parts of the body, including the brain, spine, joints, and internal organs. MRI produces images with high spatial resolution and excellent soft tissue contrast, making it a valuable tool for identifying abnormalities that may not be visible with other imaging techniques.

During an MRI scan, the patient lies on a table that slides into a large tube-shaped scanner. The scanner uses powerful magnets to align the hydrogen atoms in the body's tissues. Radio waves are then used to produce signals that are detected by the scanner and converted into images by a computer. The entire process is painless and does not involve ionizing radiation, making it a safe imaging option for patients of all ages. Depending on the area of the body being scanned, the procedure can take anywhere from 15 minutes to an hour or more.

MRI is a valuable diagnostic tool for a wide range of conditions, including cancer, stroke, multiple sclerosis, and joint and musculoskeletal disorders. It is also used in research to study the brain and other organs in great detail. Advances in MRI technology, such as functional MRI (fMRI), diffusion tensor imaging (DTI), and magnetic resonance spectroscopy (MRS), continue to improve our understanding of the body's structures and functions, leading to more accurate diagnoses and better treatment options for patients.
