MRI (Magnetic Resonance Imaging)

The phycisian need some examination to diagnose patient diseases .for that goal need some medical equipment such as x-ray ,ultrasound machine,computed tomoghrapy,bone scan and MRI.Magnetic resonance imaging (MRI) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Noninvasive is meaning that the body is not tampered with in any way. Since humans are not able to feel any type of radio waves, patients will not feel a thing. A loud tapping noise will be experienced, however, as the magnets are turned on and off throughout the exam.
MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. The images can then be examined on a computer monitor, transmitted electronically, printed or copied to a CD. MRI does not use ionizing radiation (x-rays).
Detailed MR images allow physicians to better evaluate various parts of the body and determine the presence of certain diseases that may not be assessed adequately with other imaging methods such as x-ray, ultrasound or computed tomography (also called CT, MDCT or CAT scanning).

Using MRI scans, physicians can diagnose or monitor treatments for a variety of medical conditions, including:

• Abnormalities of the brain and spinal cord
• Tumors, cysts, and other abnormalities in various parts of the body
• Injuries or abnormalities of the joints
• Certain types of heart problems
• Diseases of the liver and other abdominal organs
• Causes of pelvic pain in women (e.g. fibroids, endometriosis)
• Suspected uterine abnormalities in women undergoing evaluation for infertility

There is little to no preparation needed before getting an MRI. When you first arrive at the hospital, the doctors will ask you to change into a gown. You will also be asked to remove all accessories such as jewelry, credit cards, and any metallic objects. The reason for this is because MRIs involve magnets, which may interact with objects in your possession. This in turn may lead to bad results and/or poor image quality.
