Magnetic Resonance Imaging that is commonly known as MRI testing, is a scanning technology prescribed by doctors. This scanning technology helps the doctor in viewing deep tissues, nerves and inner regions in injured organs thus diagnosing the illness and its cause. Radio-waves are used for producing images during scanning. MRI scans are particularly helpful in investigating the root cause of the specific illness of the patient. These days, MRI scanning can be done in radiology departments of hospitals or diagnostic centers. Open and closed MRI are the 2 types of MRI machines that are distinguished on basis of the types of magnets fitted inside them.
You need to notify lab authorities and the doctor in advance, if you are pregnant, have any device implant undergone in the past or are allergic to the certain material. If exposed to the allergic material, the patient could be susceptible to another health condition. Also, women looking to become pregnant should notify the technician as the contrast agent used remains in the body for few days after the scan.
On the day of the MRI, you can eat and drink according to your routine. Before going to the center for the scan, it is advisable to take out whatever metallic ornaments, belts, hairpins, dentures etc. objects at home itself. You are made to change into a hospital gown before you lie down on the table. You need to get into a comfortable position before actual scanning begins because movements during scanning are prohibited. Sometimes noise blocking ear-phones are provided by the center or hospital.
The patient is expected to lie down on a table that slides into the MRI machine. The MRI machine is a tunnel-shaped cylindrical structure fitted with high-definition magnets. It is an open-ended machine. It is in turn attached to a computer for the doctor or technician to view the scanned images. Sometimes, a contrast agent is injected into the patient’s vein. This agent helps the technician get a neater view of muscle linings of the concerned organ. Cross-sectional images are generated because of the interaction of magnetic waves and the patient’s body particles. The bodily particles contain ions and emit radio waves. This interaction pinpoints internal structures present in the organs. You are advised to be completely still during the scanning span of 30-60 minutes. Or else there are chances of the images coming out blurred.
1. Detection of cancers: Tumors in parts like brain, breast, spine and other parts of the body may or may not metamorphose in cancer. Such tumors can be viewed through MRI imaging.
2. Joint disorders: Bone and joint disorders, inflammatory conditions in knees and many other varied disorders can be investigated through an MRI
3. Detection of heart diseases and disorders: Congenital heart defects, abnormalities in heart muscle and blood vessel complications are few disorders of heart that can be detected using an open MRI.
4. Spinal injury investigation: Injuries in spinal cord due to accident or deformity can be detected through MRI imaging as well
5. Brain injuries: Extent of brain damage after injury can be mapped through a brain MRI
1. Breathing space: An open MRI machine is wide which offers a better breathing space to the patients which a closed MRI machine doesn’t offer. That is a necessary factor since the patient has to stay put in the machine for around 30-60 minutes.
2. Utility: Open MRI is useful in inspecting deep tissues and surrounding regions.
3. Precision: Open MRI machines provide high-quality images of the aimed organ and its inner layers. Images thus produced are high on precision and accuracy.
4. Clarity: Open MRI machines provide clearer images in comparison with other scanning modalities.
5. Beneficial for claustrophobic patients: Many people have claustrophobia, meaning fear of closed spaces. Such people can undergo open MRI scanning when instructed by the doctor to undergo MRI scanning for any health issue.
6. Detailed diagnosis: Open MRI scans are known to provide a detailed and comprehensive reading of the organ undergoing scanning, making diagnosis easier.
7. No exposure to radiation: MRI does not involve any exposure as such to radiations. That makes MRI scans harmless, minimally invasive and least comfortable.
MRI imaging is an extremely superior scanning modality. It does help the patient to follow precautions and instructions given to him by the technician beforehand.
