MRI Scans in Wollongong, Warrawong and Corrimal
Magnetic resonance imaging (MRI) is a type of medical imaging used to take detailed images of the body. This imaging technique makes it possible for doctors to diagnose conditions by providing a detailed view of the inside of the body. MRI scans are most commonly used to detect abnormalities in soft tissues like ligaments, muscles, blood vessels, and organs. Unlike other imaging technologies such as X-rays or CT scans, MRIs do not involve any radiation exposure. Instead, they create highly detailed images of the internal structures in your body.
What is an MRI Scan?
An MRI scan is a non-invasive procedure that uses powerful magnets and radio waves to create high-resolution images of organs and other structures in your body. The powerful magnets generate a strong magnetic field around your body which causes the hydrogen protons in your body to align themselves with the external magnetic field.
When short bursts of radio waves are sent through your body, your protons are stimulated and spin out of equilibrium with the external magnetic field, when the radio pulse is turned off the protons realign with the external magnetic field by releasing energy which is detected by a computerised device known as a receiver coil. The receiver coil then sends the data from these signals back to the computer which creates detailed cross-sectional images of your organs or other structures in your body.
What Happens During an MRI Scan?
You will be placed inside a large round machine, where the magnetic field is created. During this process, you may hear loud tapping or buzzing noises as the magnetic field changes; however, these noises should not be loud enough to disturb you too much if you’re wearing earplugs or headphones. You may also experience slight discomfort due to lying still during the procedure; however, most people find this quite tolerable given that it only lasts for 15-30 minutes on average.
Preparation before an MRI
Before undergoing an MRI scan, it’s important to be properly prepared. Generally speaking, you’ll need to wear loose clothing without any metal fasteners such as zippers or buttons because they can interfere with the magnetic field generated by the machine. You’ll also need to remove all jewellery before entering the scanning room and may even be asked to change into special clothing provided by the facility if necessary. Additionally, if you have any implanted medical devices such as pacemakers or hearing aids, you’ll need to inform the staff member recording the scan so that they can determine whether or not it’s safe for you to undergo an MRI scan.
