MRI: A to Z Guide
An MRI (magnetic resonance imaging) procedure is used to create detailed images of the organs and tissues within the body using a strong magnetic field and radio waves.
Following are some important facts about MRI:
- MRI scan is a non-invasive and painless procedure.
- Creates detailed cross-sectional images of the internal organs and structures of the body.
- It differs from CT scans and X-Rays, as it doesn’t use potentially harmful ionizing radiation.
- MRI enables the doctors, scientists, and researchers to examine the inside of the body in high detail using a painless and non-invasive technique.
- MRI is used to treat a number of problems:
- Anomalies of the spinal cord and brain
- Cysts, tumors, and other anomalies in a variety of body parts
- Identifies breast cancer for women who face a high risk of breast cancer
- Injuries or bruises of the joints, such as the back and knee
- Certain types of heart issues
- Problems of the liver and other abdominal organs
- Evaluation of pelvic pain in women with causes such as fibroids and endometriosis
- Suspected uterine problems in women undergoing evaluation for infertility.
- The list goes endless, as the use of MRI is always expanding in its scope.
Frequently Asked Questions:
Do you need to prepare for MRI?
On your arrival, the doctor will ask you to wear a gown. Due to the use of magnets, it’s important that you are not wearing any metal objects. So the doctor will ask you to remove any metal jewellery or accessories that may interfere with the machine. Also, the person cannot undertake and MRI if they have a metal inside their body such as shrapnel, bullets or other metallic foreign bodies. The list includes cochlear implants, pacemakers, implants, and aneurysm clips.
Is MRI dangerous to your health?
As radiation is not used in an MRI, there are no risks involved. But due to the use of a strong magnet, an MRI scan is not recommended for patients with implanted pacemakers or other types of iron-based metal implants.
Can MRI scan make you sick?
No, the only few reactions that are common are minimal such as headache, nausea, and dizziness for a brief period. Some people may feel coldness at the injection site.
Is MRI better than CT?
Yes, CT scans use X-Rays to form images inside the body, but MRI uses powerful magnetic fields and radiofrequency pulses to give detailed images of organs. CT scans use harmful radiation that MRI’s do not.
How does an MRI feels like?
It’s a machine that looks like a long narrow tube with both ends open. The MRI machine makes strong magnetic field around you, in which radio waves are directed at you. This procedure is painless, as you don’t feel the magnetic field. Also, there are no moving parts around you.
