An MRI scan is the short form of Magnetic Resonance Imaging Scan. This type of scan uses a strong magnetic field and radio waves to create precise and detailed images of the internal tissues and organs of the body. An MRI scan is very useful for doctors to diagnose the issues accurately and suggest suitable treatments
MRI scanning is a painless and non-invasive procedure. The scanner resembles a large tube with a table in the middle, where the patient has to slide in. An MRI scan is better than CT scans and X-rays since it does not use any potentially harmful ionizing radiations.
When going for an MRI scan, the patient is asked to remove any metal objects like jewellery or accessories. Any person with a metal inside their body such as a bullet, shrapnel, cochlear implants, pacemakers or aneurysm clips cannot have an MRI scan.
An MRI scanner can detect anomalies of the brain and spinal cord. It can detect cysts, tumors and even breast cancer in women. Doctors suggest an MRI scan to detect abnormalities or injuries in the back and knee. It can also detect some heart problems, diseases of the liver, pelvic regions and such other internal problems.
Freequently Asked Questions About MRI-Scan
Q1. What is an MRI scan used to diagnose?
An MRI scan can be used to diagnose brain tumors, developmental anomalies, traumatic brain injuries, stroke, multiple sclerosis, infection, dementia, and causes of headache.
An MRI scan is quite valuable in diagnosing a broad range of conditions such as cancer, heart and vascular diseases, muscular and bone abnormalities and other internal injuries. It can detect abnormalities occurring in the bones using imaging methods.Q2.Is MRI scan painful?
An MRI scan is a painless procedure. It does not require an anaesthesia as it is a non-invasive procedure. Some patients tend to get claustrophobic and so, doctors administer a mild sedative to help them relax.
The procedure is painless as the patient does not feel any magnetic field or radio waves. There are no moving parts around the patient, and so, there is no sensation as well. During an MRI scan, the internal part of the magnet produces repetitive thumping, tapping and such other noises. But, patients can ask for earplugs or listen to music to block this noise.Q3. What is the Difference Between an MRI and CT scan?
Both MRI and CT scans are used to capture images within the body. The biggest difference is that MRIs – magnetic resonance imaging use radio waves, while CT scans – computerized tomography scans use X-rays.
Magnetic resonance imaging produces better and clearer images as compared to a CT scan. When doctors need to monitor the soft tissues, they suggest an MRI as it can create better pictures of the organs and soft tissues, such as herniated discs or torn ligaments.Q4. Why would a doctor order an MRI?
An MRI Scan helps doctors diagnose an injury or disease. It can monitor how well the patient is responding to the treatment and medications. MRIs are also done on different parts of the body to look closely at the soft tissues and the nervous system.
An MRI provides a better picture of the abnormal tissues. It is a better scan for detecting issues in the tendons, ligaments, spinal cord or other soft tissues. A CT scan can give you a high quality picture of the bones and is often suggested for diagnosing issues with the chest or lungs.Q5. How much does an MRI scan cost?
There are different rates of MRI scan depending upon the country, state and also on the area that needs to be scanned.
