MRI – Magnetic Resonance Imaging

Magnetic Resonance Imaging (MRI) uses radio waves and a strong magnetic field to produce detailed images of body tissues and organs. 1.5T high field Open MRI is able to accommodate patients up to 550 pounds without sacrificing image resolution. Other open field MRI’s use low-field magnets to accommodate claustrophobic or large patients, which limits diagnostic quality. The higher the field strength, the faster the scan time and the better the quality of images produced.

Preparation
A MRI technologist will review the exam with you and ask that you remove watches, hearing aids, glasses, jewelry and other items that may interfere with the scan. The technologist will escort you into the MRI area and ensure you are comfortable on the table. During the MRI, the technologist will be in direct voice communication and able to see you at all times during the procedure.

There are conditions that may prevent you from having the MRI.

  • Cardiac pacemaker
  • Certain cerebral aneurysm clips
  • Cochlear implants (inner ear)
  • Pregnancy in the first trimester
  • Neurostimulators
  • Infusion pumps such as for insulin or pain control
  • Recent vascular stent (within eight weeks of placement).
  • Metallic fragments that may be in sensitive areas, such as near the eyes

Exams
The entire MRI process will take an average of 40 to 60 minutes with procedure times varying between exams.

  • MRI Head/Brain
  • MRI Spine (Cervical, Thoracic, Lumbar)
  • MRI Breast
  • MRI Extremities (Shoulder, Elbow, Wrist, Hip, Knee, Ankle)
  • MRI Abdomen/Pelvis
  • MRA (Brain, Carotids, Renal)

Gadolinium contrast may be injected during certain exams. The contrast will enhance abnormal tissue in the body such as scar tissue or tumors. BUN & Creatinine lab values may also be required for patients over 50 years of age or with a history of kidney disease.

Results
The LRG board certified radiologist will study the images and provide a written report which includes a description of the findings. Our reports are available to your physicians within 24 hours of the completion of the exam. The report could take longer if we are waiting for studies from an outside facility for comparison. If the results are urgent your physician may acquire a preliminary report by phone.
