Which is better a CT scan or MRI?
Advantages of MRIs Magnetic resonance imaging produces clearer images compared to a CT scan. In instances when doctors need a view of soft tissues, an MRI is a better option than x-rays or CTs. MRIs can create better pictures of organs and soft tissues, such as torn ligaments and herniated discs, compared to CT images.
What are two major disadvantages of MRI scans?
Drawbacks of MRI scans include their much higher cost, and patient discomfort with the procedure. The MRI scanner subjects the patient to such powerful electromagnets that the scan room must be shielded.
Why would a doctor order an MRI?
An MRI provides a clearer picture of abnormal tissues. It is a better scan for looking at ligaments and tendons, your spinal cord and other soft tissues. A CT scan can give you a higher-quality picture of bones and is better for diagnosing chest and lung problems as well as detecting some cancers.
Can MRI results be seen immediately?
This means it's unlikely you'll get the results of your scan immediately. The radiologist will send a report to the doctor who arranged the scan, who will discuss the results with you. It usually takes a week or two for the results of an MRI scan to come through, unless they're needed urgently.
Why are MRIs so loud?
The MRI machine uses a combination of a strong magnet, radio transmitter and receiver. When the sequences are performed, electric current is sent through a coiled wire-an electromagnet. The switching of the currents causes the coils to expand making loud clicking sounds.

Frequently Asked Questions
What is Magnetic Resonance Imaging? Magnetic Resonance Imaging (MRI) is a painless and non-invasive method used by physicians to view the human body and obtain anatomical and functional diagnostic information.
What are the Advantages of the MRI Scan?
MRI scanners are designed to visualize non-bony parts or “soft tissue” areas such as muscles, ligaments and tendons. In particular, the brain, spinal cord and nerves are seen much more clearly with MRI than with regular x-rays and CAT Scans / CT Scans.
Radiation-Free Medical Imaging
There are imaging tests that use radiation, such as X-rays and CT scans. The MRI does not rely on radiation but sound waves to produce images of the body. MRI uses the natural magnetic properties of the body. While inside the machine, a radiofrequency is emitted.
Clear, Detailed Images
MRIs can create cross-sectional images of the body. This is made possible by sophisticated computer technology that combines 2D images to create 3D images.
A Whole Body Scan
An MRI machine is designed to fit the whole human body. The head-to-toe scan offers significant advantages over other medical imaging tests. Since the MRI can scan the entire body and produce cross-sectional images, doctors can detect early signs of disease or abnormalities.

This could be because the patient is suffering symptoms of sciatica, where the sciatic nerve is being pressurised and the pain is travelling all the way down the leg.
How long does it take for a back injury to heal?
It is usual for these stresses and strains to heal by themselves or as a result of physiotherapy, within about 6 weeks maximum and often within a month. An MRI scan is usually requested after a month or so, if the lower back pain shows no signs of abating.
Why does my lower back hurt when I get an MRI?
Often the basic root causes of pain in the lower back are nothing more than a strained muscle, or a stretched/strained ligament.
Why does my spine feel pressure?
Often the cause of the pressure is due to a disc in the spine becoming ruptured or protruding, which can be referred to as a herniated disc. Arthritis or the beginning of arthritis can also cause the nerve to become trapped.
Can MRI show sciatic nerve pressure?
Whilst sciatica is relatively easy to diagnose, it is more difficult to diagnose what is causing the pressure on the sciatic nerve: this is where the MRI scan comes into its own. The MRI scan can show causes that are not revealed in XRays.
Can MRI scans be used with X-rays?
Yet the fact remains that an MRI scan can show any damage to soft tissue, which simply cannot be seen within an X-ray. This can be very important in terms of eliciting which form of treatment should be used.
Can an MRI show a serious illness?
The MRI scan can also quickly show any serious underlying condition and ensure that patients can be reassured if there is no serious illness highlighted within the results of the scan. Thus your pain consultant is in the best position to indicate whether or not an MRI scan is required for your particular situation.

What happens when the radiofrequency field is turned off?
When the radiofrequency field is turned off, the MRI sensors are able to detect the energy released as the protons realign with the magnetic field. The time it takes for the protons to realign with the magnetic field, as well as the amount of energy released, changes depending on the environment and the chemical nature of the molecules.
How does an MRI work?
How does MRI work? MRI of a knee. MRIs employ powerful magnets which produce a strong magnetic field that forces protons in the body to align with that field. When a radiofrequency current is then pulsed through the patient, the protons are stimulated, and spin out of equilibrium, straining against the pull of the magnetic field.
Why do you give contrast agents before an MRI?
Contrast agents (often containing the element Gadolinium) may be given to a patient intravenously before or during the MRI to increase the speed at which protons realign with the magnetic field. The faster the protons realign, the brighter the image.
