Magnetic resonance and metal prostheses

It is not so rare that people who have undergone a metal prosthesis implant due to trauma or a pathology, may need to undergo a magnetic resonance imaging (MRI) , the diagnostic test that uses a magnetic field and frequency waves. 3D mammogram in Fair Lawn, NJ helps to obtain images of organs and anatomical structures and the main fear of patients with metal elements.

In fact, patients with metal implants can perform MRI without fear, with rare exceptions that are evaluated by the radiologist. Therefore, whether it is an examination carried out with closed magnetic resonance, or with the large magnet that is around the patient, or with the modern open magnetic resonance, prosthesis wearers can rest assured about any risks of moving screws, plates, metal sutures used for the reduction of fractures, surgery and prostheses.

The benefits of open MRI

Open MRI differs from traditional closed MRIbecause it does not involve positioning the patient inside a closed tube, it does not cause the typical rumbling sounds and therefore it is quieter than closed MRI, and the magnet is positioned only in correspondence with the part of the body to be evaluated – says Dr. Poretti – . The advantages over closed MRI mainly concern the psychological aspect and patient comfort. In fact, the exam room is smaller and more comfortable; the patient faces the exam with less discomfort since there is no “claustrophobic” component caused by the tube. For these reasons, open MRI is suitable for children, or for people suffering from panic or anxiety disorders, but also for overweight, obese and elderly people. However, open MRI does not allow the evaluation of large organs (heart, prostate, and abdomen),

  • fractures, herniated discs (cervical, dorsal, lumbar spine)
  • rotator cuff injuries and tendon (shoulder) injuries
  • meniscal and ligament (knee) injuries
  • injuries and tendonitis (ankles)

Finally, diagnostics with open magnetic resonance does not imply the use of contrast media and, as also in the case of traditional resonance imaging – concludes the expert – no specific preparation or suspension of any drugs is required “. Magnetic resonance imaging is used to study the skull, spine, spinal cord, musculoskeletal system and internal organs.
