This article is based on an Ingredient facts behind MRI Scanner machine by Mr Mohammed Sahil, Biomedical Trainer, ATHEENAPANDIAN ORGANIZATION
Introduction:
•An MRI referred as 'Magnetic Resonance Imaging'. • The first magnetic resonance scanning machine was invented by "Raymond damadian", He is the father of MRI. • After inventing an MRI, the first magnetic resonance scanning was done on 1977.
What is MRI?
• It is a Radiology imaging technique by using magnetic resonance concept. • It uses a radio wave, magnetism and computer will produce images of body structures. • It diagnosing on 3-Dimensional(3D) imaging view, very detailed scanning and better view of soft tissues, comparing CT scan.
What we need to take scanning done on MRI machine?
It will diagnose the conditions like • Brain, including tumors • Spinal cord injuries • Musculoskeletal problems • Gastrointestinal tract conditions • Soft tissue and Bone pathology Who Can’t have an MRI Scan? • a cardiac pacemaker • a cochlear implants • If you are pregnant • metallic foreign body in your eye • certain clips in your head from brain operations Principle of MRI: • The principle (Nuclear Magnetic Resonance) NMR is that many hydrogen nuclei have spin and all nuclei are electrically charged. • MRI makes use of the magnetic properties of certain atomic nuclei. • The hydrogen nuclei will partially aligned by applying strong magnetic field. • The nuclei can be rotated using radio waves, and it subsequently oscillate in the magnetic field.
Main parts of MRI Scan machine?
• Scanner (3 coils) (Static Magnetic field coil, Gradient coil, RF coil) • Computer • Recording hardware
Advantages of MRI:
• No ionizing radiation • Variable thickness in any plane • Many details without IV Contrast
Disadvantages of MRI:
• Very expensive • MRI scan will not prescribed for who have placed metallic devices within the body. • RF transmitters will cause severe burn if we have mishandled.
