1. All You Need to Know About MRI Security What is NMR and how does it work? Nuclear magnetic resonance, or MRI, is a method for producing detailed images of organs and tissues throughout the body without the need to use X-rays or "ionizing" radiation. Instead, NMR uses a powerful magnetic field, radio waves, rapidly changing magnetic fields, and a computer to create images that show if any lesion, disease or abnormal condition is present. At MRI test lab in Delhi, the patient is placed inside the NMR machine, which is usually a large, open- ended device at both ends. The powerful magnetic field aligns the atomic particles called protons that exist in most body tissues. Then, the applied radio waves cause these protons to produce signals that are detected by a receiver inside the apparatus. The rapidly changing magnetic field gives these signals specific characteristics and, with the aid of computer processing, images of the tissues are created in the form of "slices" or "slices", which can be seen in any orientation. NMR examination produces no pain, and electromagnetic fields produce no known tissue damage. Sometimes the NMR apparatus can make loud noises such as hammering, or other types of noise during the procedure. However, the use of earplugs prevents problems that could be associated with this noise. Throughout the time, it will be monitored, and you will be able to communicate with the NMR technologist or the NMR machine operator through an intercom or other means. What NMR is used for? In general, MRI creates images that may show differences between healthy and non-healthy tissues. Doctors at MRI test Center in Delhi examine the brain, spine, joints (e.g., knee, shoulder, hip, wrist and ankle), abdomen, pelvic region, sinuses, blood vessels, heart, and other parts of the body. NMR Safety The powerful magnetic field of the NMR system attracts objects containing iron (called ferromagnetic) and can move them suddenly and with great force. This poses a possible danger to the patient or anyone in the path of the object. Great care is taken to ensure that external objects such as ferromagnetic screwdrivers and oxygen tanks are not carried into the area of the NMR system. As a patient, it is vital that you remove all of your metal items before the examination; This includes hearing aids, watches, jewelry, cell phones, and garments with wire or metal hooks. Also, make-up should be removed, The MRI system will attract all objects in the body that contain iron, such as aneurysm clamps or drug pumps. MRI test lab in Delhi/Ncr has a detailed procedure and control protocol which, if carefully followed, ensures that the NMR technologist and the radiologist are aware of the presence of any implant or metal material so that they can be taken special precautions. In some rare cases, the exam may need to be cancelled due to the presence of an implant or apparatus that is unsuitable for examination. For example, MRI will not be performed when there is a ferromagnetic aneurysm clamp present because there is a risk that the fastener will move and cause serious injury to the patient. In some cases, medical implants may be heated during the MRI examination as a result of the radiofrequency energy that is used for the procedure, which can also cause injury to the patient.

2. Therefore, it is essential to inform the NMR technologist about any implants or other internal objects you may have. The magnetic field of the NMR system can damage an external hearing instrument or cause a cardiac pacemaker, an electrical stimulator, or a neurostimulator to malfunction or cause harm. If you have a bullet or any other fragment of metal in your body, there is a chance that it may change position and possibly cause injury.
