MRI scan is a medical imaging technique that doesn’t involve X-ray but uses a strong magnetic field to generate high-quality images of organs. The GE SIGNA Creator Digital 1.5 Tesla MRI is available at our MRI centre in Thrissur.
The technique is widely used for medical diagnosis. It has a wide range of applications in medical diagnosis: neuroimaging, cardiovascular, musculoskeletal, gastrointestinal, and angiography. It is the investigation of choice in the preoperative staging of many carcinomas and has a role in diagnosis, staging, and follow up of tumors. An investigative tool for neurological carcinomas, it offers better visualization of the posterior cranial fossa, containing the brain stem and cerebellum.
MRI is a non-invasive diagnosing technique involving magnetic fields and radio waves. The scanning machine looks similar to a large tube. Strong magnets surround the structure. The patient is placed on an adjustable surface at the nearer mouth of it. During the process, the patient moves inside the tube into the strong magnetic field
The strong magnetic force aligns the protons of the patient to the direction of the magnetic field. The introduction of radiofrequency spins these protons, and once the radio waves are cut off, the protons go back to their previous position aligning to the magnetic field.
The energy released and the time taken for this realignment process changes according to the chemical nature of the body. Contrast agents are given to patients through for some exceptional cases to get brighter images in MRI centers.
MRI scan produces clear images of tissues and non-bony parts like muscles, nerves, tendons compared to an x-ray or a CT scan. MRI scanning process does not involve the use of any harmful radiations like an x-ray. Conditions that can be diagnosed in an MRI scan centre includes:
Although the scan does not involve any ionizing radiation, the strong magnetic field can cause severe effects on a minority category. Below are the groups at risk when undergoing procedures in an MRI scan centre.
The standard technology for MRI scans is 1.5 Tesla MRI Scan, and they are the most commonly used type of scan technology. 1.2T and 3T MRI scans are the other specifications available. Open and wide-bore are two types of MRI scans based on size. Tesla is the measuring unit of the magnetic field produced by the machine in the scan center. The 1.5 Tesla MRI Scan is capable of producing a high-quality image within a short period compared to a 1.2T MRI scan.
Our scheduling staff will block convenient slots for the scanning procedure. Please report 15 minutes prior to the appointment time to verify the documents. Make sure that you remove all the metal items from the body like ornaments, hairpins, etc. This may affect the quality of the result and can cause discomfort to you.
