Definition of Repeat MRI Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic technique that provides detailed images of the body’s internal structures. Occasionally, a patient may need to undergo a second MRI scan, commonly referred to as a repeat MRI. This occurs when the initial imaging does not fully meet diagnostic requirements due to various […]
Definition of Radiation Radiation refers to the emission and propagation of energy through space or a medium in the form of waves or particles. Originating from the Latin word “radius,” meaning ray or beam, radiation encompasses a broad spectrum of energy types that permeate various environments-from cosmic space to everyday life. It plays a crucial […]
