Medical imaging and computerized image processing have been characterized by significant technological advancements over the last three decades. The advancement in these technologies has led to the development of more sophisticated and efficient imaging modalities that have significantly improved both diagnosis and treatment of various diseases. These technologies provide medical practitioners with the capability to obtain detailed information related to the anatomy, physiology, metabolic, and other useful information from the human body.

The most common imaging technologies include; Ultrasound, Computed Tomography ( CT scan), X-Rays, Magnetic Resonance Imaging (MRI), Single Photon Emission Computed Tomography (SPECT), and Positron Emission Tomography (PET). These technologies have undergone continuous advancement over the years and are currently characterized by complex instrumentation and the use of hi-tech computer technology for data collection and image reconstruction. Among these medical imaging technologies, Magnetic Resonance Imaging has become the most favorable and outstanding imaging technology for medical practitioners as well as researchers.

Since its inception in the early 1970s, Magnetic Resonance Imaging (MRI) has rapidly developed into an invaluable medical imaging technology.Magnetic Resonance Imaging is regarded as an invaluable medical imaging technology because of its ability to produce images of outstanding quality non-invasively with no adverse side effects such as exposure to X-ray radiation. MRI is a versatile imaging technology and is widely used to image soft tissues of the body. It is also the most preferred technology in other imaging applications such as observing blood flow, distinguishing the gray and white matter of the brain, and measuring cortical thickness among other diagnostic as well as medical research applications.
