Introduction to Magnetic Resonance Imaging (M.R.I)

What is Magnetic Resonance Imaging (M.R.I)?

Magnetic Resonance Imaging (M.R.I), which is also known as Quantum Local Call or Quantum machine for short, is a technique for producing images of the organs in the body by measuring the response of the atomic nuclei of body tissues to high-frequency radio waves when placed in a strong magnetic field. You must have seen this quantum machine with some local drug or supplements sellers like GYM centers and people that sell drugs or supplements for companies like Forever Living, GNLD, GreenLife, etc.

Some agents who sell drugs take quantum machine to different places like school, market, church, mosque etc., to check peoples’ health. However, the Box or panel called Quantum Machine is just an ordinary Health Apparatus that consists of all human anatomy and physiology; but it has not been programmed specially for specialist use.
The Quantum Machine becomes specialist Machine when you install the types of application that will work for your area of specialization. For example, if you buy an android phone at the rate of N10,000 and then programmed a lot of applications that worth N40,000 into it in order to make it useful for your purpose, this will make your android phone different from the same type of android phone, and will add more value, cost and more importance to your profession.
This is applicable to just ordinary Quantum Machine you see around, that people use freely for test to sell their drugs. These types MRI have no special devices, they are just like a phone that comes with company little application and games. Taking your phone to an engineer for more applications makes it more useful and different from that same type. It can now do the work that other of the same phone cannot do. Moreover, you cannot say because you want to make your phone different from others so that people can respect your job that you do on it, now install what is meant for a car on the phone. It is phone or laptop you will use no matter how common car is.
At G.V.M. Alternative Medical and Hospital, we have Magnetic Resonance Imaging (M.R.I) machine just the same Apparatus of Quantum, but we take to our oversea partner, - the Indian Board of Alternative Medicine to install all applications that are useful for use in our hospital. Uses include; I.V.F, Diagnostics, Gynecology Case Health, Maternity, Obstetrics, Insanity, Epilepsy, Tube Blockage, Ovarian Cyst, No Menses, No sperm, Low sperm, Knowing all causes of ailment Diseases, Delay in child Bearing and Knowing the solution. It can be used to find out problems such as: tumors, bleeding, injury, blood vessel diseases, or inflections.
The Magnetic Resources Images can only be interpreted by radiologist net and other profession like; Zoologist, Lab Technician, Lab scientist, or other areas of medical specializations or Radiologist that know about the M.R.I. machine. Welcome to New World of Technology.

To show abnormal tissue more clearly, an M.R.I scan can be done for the:

Head
MRI can look at the brain for tumors, an aneurysm, bleeding in the brain, nerve injury, and other problems, such as damage caused by a stroke. MRI can also find problems of the eyes and optic nerves, and the ears and auditory nerves.

Chest
MRI of the chest can look at the heart, the valves, and coronary blood vessels. It can show if the heart or lungs are damaged. MRI of the chest may also be used to look for breast cancer.

Blood Vessels
Using MRI to look at blood vessels and the flow of blood through them is called Magnetic Resonance Angiography (MRA). It can find problems of the arteries and veins, such as an aneurysm, a blocked vessel (dissection). Sometimes contract materials are used to see the blood vessels more clearly.

Abdomen and Pelvis
MRI can find problems in the organs and structures in the belly, such as the liver, gallbladder, pancreas, kidney, and bladder. It is used to find tumors, bleeding, inflection, and blockage. In women, it can look at the Uterus and Ovaries. In men, it looks at the prostate.

Bones and joints
MRI can check for problems of the bones and joints, such as arthritis, problems with the temporomandibular joints, bone marrow problems, bone tumors, cartilage problems, torn ligaments or tendons, or infection. MRI may also be used to tell if a bone is broken when X-ray results are not clear. MRI is done more commonly than other tests to check for some bone and joint problems.

Spine
MRI can check the discs and nerves of the spine for conditions such as spinal stenosis, disc bulges, and spinal tumors.
How To Prepare for MRI scan
Before you go for MRI Test, tell your doctor and the MRI technologist if you:

  • Are allergic to any medicines. The contrast material used for MRI does not contain iodine. If you know that you are allergic to the contrast material used for the MRI, tell your doctor before having another test.
  • Have a health condition, such as diabetes, Sickle Cell Anemia or Kidney problems. You may need to change your medicine schedule and some conditions may prevent you from having an MRI using contrast material.
  • Are you a nursing mother or may be pregnant.
  • Have any metal implanted in your body. This helps your doctor know if the test is safe for you. Tell your doctor if you have:
    * Heart and blood vessel devices such as a coronary artery stent, a pacemaker, an ICD (implantable cardioverter-defibrillator), or a metal heart valve.
    * Any other implanted medical device, such as a medicine infusion pump or a cochlear implant
    * Cosmetic metal implants, such as in your ears, or tattooed eyeliner.
  • Had recent surgery on a blood vessel. In some cases, you may not be able to have the MRI test.
  • Have an intrauterine device (IUD) in place. An IUD may prevent you from having the MRI test do.
  • Become very nervous in confined spaces. You need to lie very still inside the MRI magnet, so you may need medicine to help you relax. Or you may be able to have the test done with open MRI equipment. It is not as confining as standard MRI machines. Wear any medicine patches. The MRI cause a burn at the patch site.

You may need to arrange for someone to drive you home after the test, if you are given a medicine (sedative) to help you relax.
For an MRI of the abdomen or pelvis, you may be asked to not eat or drink for several hours before test.
You may need to sign a consent from that says you understand the risks of the test and agree to have done.
Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will done, or what the results will mean. To help you understand the importance of this test, fill out the medical test information form.

How it feels
You will not have pain from the magnetic field or radio waves used for the MRI test. The table you lay on may feel hard and the room may be cool. You may be tired or sore from lying in one position for long time.
If a contrast material is used, you may feel some coolness when it is put into your IV.
In rare cases, you may feel:
- A tingling feeling in the mouth if you have metal dental fillings.
- Warmth in the area being examined. This is normal. Tell the technologist if you have nausea, vomiting, headache, dizziness, pain, burning, or breathing problems.

How it is done
A magnetic resonance imaging (MRI) test is usually done by an MRI technologist. The pictures are usually interpreted by a radiologist. But some other doctors can also interpret an MRI scan. You will need to remove all metal objects (such as hearing aids, dentures, jewelry, watches, and hairpins) from your body because these objects may be attracted to the powerful magnet used for test. You will need to take off all or most of your clothes; depending on which area is being examined (you may be allowed to keep on your underwear if it is not in the way). You will be given a gown to use during the test if you are allowed to keep some of your clothes on, you should empty your pockets of any coins and cards (such as credit cards or ATM cards) with scanner strips on them because the MRI magnet may erase the information on the cards.
During the test, you usually lie with your back on a table that is part of the MRI scanner. Your head, chest and arms may be held with straps to help you remain still. The table will slide into the space containing the magnet. A device called a cell may be placed over or wrapped around the area to be scanned. A special belt strap may be used to sense your breathing or heartbeat. This triggers the machine to take the scan at the right time.
Some people feel nervous (claustrophobic) inside the MRI magnet, if this keeps you from lying still; you can be given a medicine (sedative) to help you relax. Some MRI machines are now made such that the magnet does not enclose your entire body. Open MRI machines may be helpful if you are claustrophobic.
Inside the scanner you will hear a fan and feel air moving. You may also hear trapping or snapping noises as the MRI scans are taken. You may be given earplugs or headphones with music to reduce noise. It is very important to hold completely still while the scan is being done. You may be asked to hold your breath for short periods of time.
During the test, you may be alone in the scanner room. But the technologist will watch you through window. You will be able to talk with the technologist through a two-way intercom.
If contrast material is needed, the technologist will put it in an intravenous (IV) line in your arms. The material may be given over 1 to 2 minutes. Then more MRI scans are done.
An MRI test usually takes 30 to 60 minutes but can take as long as 2 hours.

Risks
There are no known harmful effects from the strong magnetic field used for MRI. But the magnet is very powerful. The magnet may affect pacemakers, artificial limbs, and other medical devices that contain iron. The magnet will stop a watch that is close to the magnet. Any loose metal object has the risk of causing damage or injury if it gets pulled toward the strong magnet.
Metal parts in the eyes can damage the retina. If you may have metal fragments in the eye, an X-ray of the eyes may be done before the MRI. If metal is found, the MRI will not be done.
Iron pigments in tattoos or tattooed eyeliner can cause skin or eye irritation. An MRI can cause a burn with some medicine patches. Be sure to tell your health professional if you are wearing a patch. There is a slight risk of an allergic reaction if contrast material is used during the MRI. But most reactions are mild and can be treated using medicine. There also is a slight risk of an infection at the IV site.
If you breastfeed and are concerned about whether the dye used in this test is safe, talk to your doctor. Most experts believe that very little dye passes into breast milk and even less is passed on to the baby.
But if you prefer, you can store some of your breast milk ahead of time and use it for a day or two after the test.

Results
A magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body.
The radiologist may discuss initial results of the MRI with you right after the test. Complete results are usually ready for your doctor in 1 to 2 days.
An MRI can sometimes find a problem in a tissue or organ even when the size and shape of the tissue or organ looks normal.

Magnetic resonance imaging (MRI)
Normal:
- The organs, blood vessels, bones, and joints are normal in size, shape, appearance, and location.
- No abnormal growths, such as tumors are present
- No bleeding, abnormal fluid, blocking in the flow of blood, or bulges in the blood vessels (aneurysms) are present
- No signs of inflammation or inflection are present

Abnormal:
- An organ is too large, too small, damaged, or absent
- Abnormal growths (such as tumors) are present
- Abnormal fluid from a cause such as bleeding or an infection is present. Fluid is found around the lungs or heart. Fluid is found around the liver, bowel, or other organ in the abdomen
- A blood vessel is narrowed or blocked. An aneurysm is present
- Blockage in the gallbladder bile ducts or in the tubes (ureter) that lead out of the kidneys is present
- Damage to joints, ligaments, or cartilage is seen. Bones are broken or show infection or disease
- Problems of the nervous system are present, such as multiple sclerosis (MS), dementia, Alzheimer disease, or herniated disc.

What affects the test?
Reasons you may not be able to have the test or why the results may not be helpful include
- Pregnancy: An MRI test usually is not done during pregnancy. But MRI may be done to get more information about a possible problem that cannot be seen clearly with ultrasound
- Medical devices that have use electronics, such as a pacemaker or medicine infusion pump. The MRI magnet may cause problems with these devices, and that may keep you from having an MRI
- Medical devices that have metal in them. The metal might make some of the detailed MRI picture blurry. This may prevent your doctor from seeing the organ that is being looked at. For example, an intrauterine device (IUD) with metal may prevent your doctor from seeing the uterus clearly
- Inability to remain still during the test
- Obesity: A person who is very overweight may not fit into standard MRI machines.

Many modern medical devices that do not use electronics-such as heart valves, stents, or clips-can be safety placed in most MRI machines. But some newer MRI machines have stronger magnets. The safety of MRI scans with these stronger MRI magnets in people with medical devices is not known.

What to think about
- Sometimes your MRI test results may be different from the results of CT, ultrasound, or X-ray tests, because the MRI scans shows tissue differently
- MRI is a safe test for looking at structures and organs inside the body. It costs more than other methods and may not be available in your area
- Open MRI machines are now made so that the magnet does not completely surround you. But these machines may not be available in all medical centers. Open MRI is useful for people who are claustrophobic or obese
- Magnetic resonance angiogram (MRA) is a special MRI method that studies blood vessels and blood flow. To learn more, see the topic Magnetic Resonance Angiogram (MRA)
- MRI spectroscopy is a special MRI method that identifies certain medical problems by looking for specific chemicals in body tissues
- Contrast material that contains gadolinium may cause a serious skin problem (called nephrogeric fibrosing) if you have serious kidney disease or if you have had a kidney transplant.

MRI can be used to check different parts of the body, such as the head, belly, breast, spine, shoulder, and knee.
