MRI Scan

Precision Imaging with

MRI Scan

Magnetic Resonance Imaging (MRI) is a non-invasive medical imaging technique that is often used to visualize and examine internal structures of the body with exceptional clarity and detail. The imaging technique leverages a robust magnetic field, radio waves, and advanced computer technology to generate and display very high-quality cross-sectional images of the internal organs that can help in precise and timely diagnosis. Used for various diagnostic and screening purposes, MRI provides valuable insights into several medical conditions without generating the need to subject the patients to ionizing radiations of other scans.

Overview of the Key Aspects of MRI:

Types of MRI Machines: 

MRI machines are often available in various types such as closed MRI machines and Open MRI machines. Open MRI machines are particularly designed to accommodate patients who have trouble lying flat or have claustrophobia. Closed MRI machines have a tunnel-like or cylindrical shape that elevates the magnetic field to generate more precise and detailed images.

Procedure: 

●       During the MRI procedure, the patient is often made to lie flat on the table equipped with motors that smoothly slides inside the MRI machines.

●       Depending on the body part to be scanned, the patient is moved on the scanner either through the side of the head or feet.

●       It is crucial to remain still during the scan to avoid blurry or unclear images.

●       The machines generate a robust magnetic field around a patient’s body with radio waves directed at the body. Since it is not felt, the procedure is relatively painless.

●       As the scan starts, the magnetic inside the machine make a whirring and tapping sounds that are repetitive.

●       Although these sounds are not harmful in any way, earplugs or headphones may be offered to patients with sensitive hearing.

●       The scan can last from 15 minutes to more than an hour depending on the requirement for the scan.

●       In rare cases, a contrast material can be injected into a vein through an intravenous line which can enhance imaging and improve precision of diagnosis.

Benefits of MRI

●       Non-invasive and painless imaging process

●       Offers exception soft-tissue contrast for accurate differentiation and diagnosis

●       Generally considered safe

●       Can effectively diagnose several medical conditions related to joint injuries, neurological disorders, tumors, cardiovascular diseases, and abdominal conditions, among others

●       Reduces the need for high ionizing radiation imaging such as CT scan and X-rays

It is important for patients to inform their medical provider and radiologists about any metal implants such as plates, screws, or pacemakers and other medical conditions before undergoing MRI scanning to avoid any complications from arising. Patients need to wear comfortable clothing’s, preferably without metal zips or buttons and must avoid watches, hairpins, and piercings. In addition, patients need to inform their healthcare provider in case of any kidney issues, allergies, or pregnancy-related details in case contrast agents may need to be administered.
