It is used in taking the images of heart, muscles and the brain because it differentiates the body tissues prominently than any other imaging process. It does not make use of ionizing radiations as radiographs and tomography. It is quite different from the CT scan in respect to the position of the image as Interventional Radiology provides the images from all angles and CT scans show the images horizontally. The patient is laid in a huge magnet which is cylindrical in shape. The wave that are passed through the patients body have magnetic field 30,000 stronger that the magnetic field of earth. While this procedure the atoms present inside our body gets affected and tends to change the position of the nuclei. Due to the movements, the star producing radio waves of them, this is picked up by the scanner and then turned into an image with the help of the computer. The image thus formed is the related to the location of the incoming signals. The nucleus of the hydrogen atom present in our body in the form of water helps in the creation of MRI scans. Interventional Radiology is used to create the images of almost all the tissues present in our body. The tissue in which the hydrogen content is low appears to be dark such as bones, and the tissues having more water are brighter. We can get clear images of those body parts that are located in between bone tissue, for example brain. It is commonly used to diagnose tumors. The patient on whom Interventional Radiology is performed cannot go home after the test. As it uses strong magnetic fields, the patient is restricted to wear any jewelry or metal objects. Patients with pacemaker are not allowed to go through this test.
