Diagnostic imaging is the cornerstone of modern medicine, allowing physicians to see inside the body without surgery. Each imaging modality uses different physical principles to reveal different types of information. X-rays pass through the body and are absorbed at different rates by different tissues, producing images where dense structures like bones appear white and air-filled areas appear black. This makes X-ray ideal for detecting fractures, lung infections, and dental problems. CT scanning takes this concept further by combining multiple X-ray images taken from different angles to create detailed cross-sectional views of the body, providing far more information than a single X-ray image.

Magnetic Resonance Imaging, or MRI, works on an entirely different principle. It uses powerful magnetic fields and radiofrequency pulses to excite hydrogen atoms in the body, then detects the signals they emit as they return to their resting state. Different tissues produce different signal characteristics, creating exceptionally detailed images of soft tissues including the brain, spinal cord, muscles, ligaments, and internal organs. Because MRI does not use ionizing radiation, it is considered very safe and can be repeated as often as clinically necessary without cumulative radiation concerns.
