What is MRI Scan? MRI (magnetic resonance imaging) scan as shown in figure 1 is a radiology technique that uses a strong magnetic field and radio waves to generate images of parts of the body that cannot be seen as well with X-rays, CT scans or ultrasound.The image and resolution produced by MRI is quite detailed and can detect tiny changes of structures within the body. MRI scan is the best way to see internal of human body without cutting it open. Figure 1- label diagram of MRI History of MRI The history of MRI was began in 1945. It all started when Felix Bloch(figure 2) which is a Swiss Physicist conducted a new experiment regarding a study of nuclear moments in solids, liquids, or gases.

One of the reasons is is because MRI do not involve the exposure of radiation. Therefore people such as pregnant woman and babies who might be vulnerable to the effects of radiation can also safely use. It is also useful for scanning and detection of abnormalities soft tissue structures, such as ligaments and cartilage, and organs such as the brain , heart, and eyes. Besides, blockages can be identified by providing information about the blood circulation throughout the body and blood vessels The disadvantages of using MRI include MRI scanners are very expensive. In addition, MRI scans give out a very loud noises while processing because they involve a really high amount of electric current supply. MRI often has trouble producing high quality images in parts of the body that move, making them unsuitable for investigating problems such as mouth tumours because of coughing, or swallowing, can make the image that are produced less clear. Lastly, bone and calcium do not show up on an MRI scan. So diseases such as osteoporosis cannot be detect using MRI scanning.Bone and calcium do not show up on an MRI
