MRI or Magnetic Resonance Imaging is one of the best medical imaging techniques of the world. It is also very common nowadays and preferred by most doctors in Australia. This is because it is a type of medical imaging which uses magnetic fields and gradients and radio waves to capture the anatomical images and psychological functioning of the body parts. It helps a doctor know about various fatal diseases in the body and its functioning.
Now there are CT and CAT scans, X-rays, PET scans, etc. Then why is MRI preferred more? The fact that makes MRI scan different from the other imaging techniques is that it does not use harmful ionizing radiations like the other scans, rather it uses the less harmful and more efficient technique of magnetic fields and radio waves.
Significance of MRI scan
An MRI scan is highly recommended when you suffer a bone damage or tissue damage or any muscular problems due to any accidents. Doctors recommend it to diagnose various types of medical issues. Just as MRI can show in great detail about abnormalities in soft tissues, there is another similar imaging called MRA (Magnetic Resonance Angiography). It is a variation of MRI. It can picture the flow of blood in the body and can detect clots and other such irregularities in the body.
Who can get an MRI scan done?
Well, not everyone is eligible for an MRI scan. Why? Because it emits and creates a very strong magnetic field to do the process, which may turn out to be harmful to the body, if the body is not suitable for such strong magnetic fields.
The types of people not eligible for an MRI are:
- A person having any permanent metallic piercings or insertion of rods due to surgeries
- A person who recently has undergone surgery
- A pregnant lady (though it is not harmful to the foetus, still it’s not advisable)
- A person having a pacemaker installed in his body
- A person with a cochlear transplant
How is an MRI scan done?
The whole process is machinery. There is very less involvement of manual tasks. MRI scan is done firstly in a chamber with very less magnetic objects. Before any person enters the chamber, he or she is thoroughly checked and brushed off of any magnetic elements on or in the body. Inside the chamber, there is a movable table and the MRI machine.
The person to be scanned lies down on the table, and the technician then makes the table move inside the MRI machine till the part which is to be scanned. Once the placement is done, the machine is switched on, and it creates a strong magnetic field around that part. Due to the strong magnetic field and radio waves, the protons of the hydrogen atoms start to spin with the protons of the body producing a faint signal on the MRI scanner’s receiver. This signal is then converted into an image by the computer attached to the MRI machine.
Usually, the process is painless, but sometimes a claustrophobic person may have some problems like uneasiness or headaches. In such a case, a sedative is given to the person to help ease the MRI process for that person.
The Test Results
The outcome or the image or the result of the MRI scan usually takes a couple of hours to be generated by the computer. The time taken to get the result depends according to the part of the body scanned and the nature of the problem. This is because different tissues of the body send different types of signals to the signal interceptor. A good tissue will send a different signal than a cancerous or a diseased tissue. Thus, the more complicated the internal organs and tissues are, the more time it requires to attain the image. After the image is generated, it is now time to prepare the report. The diagnostician then sits to file the report of the scan. He studies the image using his professional skill and knowledge and prepares the report in the most accurate form.
Once all this is done, the report is given to the patient or the doctor who then further studies the case based on the report, and the MRI scanned image and then prescribes further actions to be taken by the patient.
MRI in Australia
MRI in Australia came almost as soon as it was discovered. The major development of the MRI scan was done in the three top medically advanced countries viz. The United Kingdom, the United States and India. India, because of its huge population and requirement needs help to research more on this scan and develop it. MRI scan in Hyderabad India is very renowned. Nowadays there is an MRI scanner in almost every hospital in Australia. Most diagnostic centers too now possess an MRI scanner.
Sydney and Melbourne are medical treatment hubs of Australia. Almost all medical facilities are abundant here. Brisbane is another city not behind it. According to a majority of people of Australia, for MRI, Melbourne is the best nowadays. Melbourne is growing day by day with lots of advanced and better quality MRI scans than the rest of Australia.
What types of MRI scan is available in Melbourne?
There are almost all varieties of MRI scan in Melbourne. Some of them are mentioned below:
- MRI Abdomen
- MRI Abdomen and Pelvis
- MRI Angiogram
- MRI Ankle
- MRI Arm
- MRI Arthrogram.
These types top in quality of MRI. Melbourne also now has started making MRI cheaper than others in Australia. A good quality MRI in Melbourne will cost between $100 – $500 depending on which body part is to be tested. In other cities, it can cross more than this too as because of their involvement of more technicians and other “not so necessary resources”.
MRI is a revolutionary imaging technique in the medical world. Invention of it has helped doctors recognize fatal diseases beforehand. But there must always be a control in development. In the process of developing the MRI system, it should be kept in mind that it does not turn out to be harmful to the body.
