TECHNOLOGY USED IN G SCAN (OPEN MRI)


An MRI Scan utilizes a strong magnetic field and radio waves to create detailed images of the organs and tissues within the body. Its main use is for musculoskeletal disorders in weight bearing areas.


HOW IS G SCAN (OPEN MRI) TEST PERFORMED


Conventional MRI can be difficult for people with claustrophobia, for children and for people who are physically large. Open MRI can solve this problem. With an open MRI system, the patient lies on an imaging table with free space on all sides. Before the exam you will be asked to fill out a screening form asking about anything that might create a health risk or interfere with imaging. Items that may create a health hazard or other problem during an MRI exam include:

  • Cardiac pacemaker or implantable defibrillator
  • Catheter that has metallic components that may pose a risk of a burn injury
  • A ferromagnetic metallic vascular clip placed to prevent bleeding from an intracranial aneurysm
  • An implanted or external medication pump (such as that used to deliver insulin or a pain-relieving drug)
  • A cochlear (inner ear) implant
  • A neurostimulation system
  • A catheter that has metallic components that may pose a risk of a burn injury.

Items that need to be removed by patients and individuals before entering the MR system room include:

  • Purse, wallet, money clip, credit cards, cards with magnetic strips
  • Electronic devices such as beepers or cell phones
  • Hearing aids
  • Metal jewellery, watches
  • Pens, paper clips, keys, coins
  • Hair barrettes, hairpins
  • Any article of clothing that has a metal zipper, buttons, snaps, hooks, underwire, or metallic threads
  • Shoes, belt buckles, safety pins

Objects that may interfere with image quality if close to the area being scanned include:

  • Metallic spinal rod
  • Plates, pins, screws, or metal mesh used to repair a bone or joint
  • Joint replacement or prosthesis
  • Metallic jewellery including those used for body piercing
  • Some tattoos or tattooed eyeliner.
  • Makeup, nail polish or other cosmetic that contains metal
  • Bullet, shrapnel, or other type of metallic fragment
  • Metallic foreign body within or near the eye (such an object generally can be seen on an x-ray; metal workers are most likely to have this problem)
  • Dental fillings (while usually unaffected by the magnetic field, these may distort images of the facial area or brain; the same is true for orthodontic braces and retainers)

In some cases, a contrast material, typically gadolinium, may be injected through an intravenous (IV) line into a vein in your hand or arm. The contrast material enhances the appearance of certain details. The material used for MRIs is less likely to cause an allergic reaction than the material used for CT scans.

An MRI can last up to an hour or more. You must hold very still because movement can blur the resulting images.

WHY IS G SCAN (OPEN MRI) TEST DONE?


Open MRI or G -SCAN is a kind of MRI which has following advantage in comparison to conventional closed MRI

  • It can be used for claustrophobic patient.
  • It provide ease for MRI scan for obese patients.
  • It helps in better evaluation of the spine and weight bearing joint. There are significant bio-mechanical changes from the recumbent to the weight-bearing position, and several pathologies are affected by these mechanical changes. MR imaging of the spine in the natural standing position is therefore the most logical solution, and that is exactly how the G-Scan gives a better view.

G SCAN (OPEN MRI) TEST RISKS


There are no known harmful side-effects associated with temporary exposure to the strong magnetic field used by MRI scanners.
