Magnetic resonance imaging: new horizon in diagnostic techniques.

Magnetic Resonance Imaging (MRI) as a new diagnostic technology has the capacity for both imaging of body tissues or organs in action and spectroscopy which examines the chemistry of individual cells in health and disease. The principles and application of imaging without the use of ionizing radiation are presented. Potential hazards associated with magnetic resonance imaging center primarily around metal implants, metal prosthesis, and cardiac pacemakers. While this scanning is considered a painless procedure, there are several areas where patient teaching and support are important.
