Abstract
Introduction
In today’s world, MRI emerged as one of the most prompting modalities in the field of research and diagnostic imaging. MRI has an excellent imaging in diagnosis of certain diseases and lesions(8). Growth in number of MRI scans all over the world is because of its superior soft-tissue contrast, physiological and functional applications compared with other modalities(5).
Magnetic resonance imaging (MRI) is an established diagnostic and research tool in the field of diagnostic imaging mainly because of its excellent soft tissue delineation [1].The very first MRI scan on human body was recorded in the year 1977. MRI has proven itself to be magnificent and multifaceted imaging technique in the field of diagnostic imaging. MRI uses magnetic and radio waves to create high resolution images of structures and organs present inside human body.
In an MRI, hydrogen atom which is present abundantly in human body act as natural magnet. When the patient is kept inside the magnetic bore of MRI, the atoms of hydrogen align themselves in parallel or anti-parallel. The alignment of atom occurs because of presence of strong magnetic field. When the RF pulse is sent, the protons are in excited state.
