MRI Musculoskeletal

What is musculoskeletal MRI?
MRI is a noninvasive medical test that helps physicians diagnose and treat medical conditions.
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 evaluate various parts of the body and determine the presence of certain diseases.

Why should I do it?
MR imaging is usually the best choice for examining the:

  • Body's major joints.
  • Spine for disk disease.
  • Soft tissues (muscles, tendons and ligaments) and bones of the extremities.
  • MR imaging is typically performed to diagnose or evaluate:
  • Degenerative joint disorders such as arthritis and meniscus tears (knee) or labral tears (shoulder and hip).
  • Fractures (in selected patients).
  • Joint abnormalities due to trauma (such as tears of ligaments and tendons).
  • Spinal disk abnormalities (such as a herniated disk).
  • The integrity of the spinal cord after trauma.
  • Sports-related injuries and work-related disorders caused by repeated strain, vibration or forceful impact.
  • Infections (such as osteomyelitis).
  • Tumors (primary tumors and metastases) involving bones and joints.
  • Pain, swelling or bleeding in the tissues in and around the joints and extremities.
  • Congenital malformations of the extremities in children and infants.
  • Development abnormalities of the extremities in children and infants.
  • Congenital and idiopathic (developing during adolescence) scoliosis prior to surgery.
  • Tethered spinal cord (abnormal stretching in the spinal cord) in infants and children.

Any preparations needed?

  • Guidelines about eating and drinking before an MRI exam vary with the specific exam.
  • The radiologist or technologist may ask if you have allergies of any kind, such as allergy to iodine or x-ray contrast material, drugs, food, the environment, or Asthma.
  • The radiologist should also know if you have any serious health problems, or if you have recently had surgery.
  • Women should always inform their physician or technologist if there is any possibility that they are pregnant.
  • If you have claustrophobia (fear of enclosed spaces) or anxiety, you may want to ask your physician for a prescription for a mild sedative prior to the scheduled Examination.
  • Jewelry and other accessories should be left at home if possible, or removed prior to the MRI scan. These items include
    • Jewelry, watches, credit cards and hearing aids, all of which can be damaged.
    • Pins, hairpins, metal zippers and similar metallic items, which can distort MRI images.
    • Removable dental work.
    • Pens, pocket knives and eyeglasses.
  • People with the following implants cannot be scanned and should not enter the MRI scanning area unless explicitly instructed to do so by a radiologist or Technologist who is aware of the presence of any of the following:
    • Internal (implanted) defibrillator or pacemaker
    • Cochlear (ear) implant
    • Some types of clips used on brain aneurysms
    • Some types of metal coils placed within blood vessels
  • You should tell the technologist if you have medical or electronic devices in your body, because they may interfere with the exam or potentially pose a risk, Depending on their nature and the strength of the MRI magnet. Some implanted devices require a short period of time after placement (usually six weeks) Before being safe for MRI examinations. Examples include but are not limited to:
    • Artificial heart valves
    • Implanted drug infusion ports
    • Implanted electronic device, including a cardiac pacemaker
    • Artificial limbs or metallic joint prostheses
    • Implanted nerve stimulators
    • Metal pins, screws, plates, stents or surgical staples
  • A recently placed artificial joint may require the use of another imaging procedure. If there is any question of their presence, an x-ray may be taken to detect And identify any metal objects.
  • Patients who might have metal objects in certain parts of their bodies may also require an x-ray prior to an MRI.
  • Parents who accompany children into the scanning room also need to remove metal objects and notify the technologist of any medical or electronic devices They may have.
  • Infants and young children may require sedation or anesthesia to complete an MRI exam without moving
