ABOUT MRI SCAN
Magnetic resonance imaging (MRI) is a
medicalimaging technique that uses a strong
magnetic field and radio waves to create
detailed images of the inside of the body.

HOW MRI WORKS
MRI WORKS BY TAKING ADVANTAGE OF THE FACT THAT
THE NUCLEI OF ATOMS, SUCH AS HYDROGEN, HAVE A
MAGNETIC MOMENT. WHEN A PATIENT IS PLACED IN A
STRONG MAGNETIC FIELD, THE NUCLEI OF THESE
ATOMS ALIGN THEMSELVES WITH THE
FIELD. A RADIOFREQUENCY PULSE IS THEN
APPLIED, WHICH CAUSES THE NUCLEI TO
FLIP OUT OF ALIGNMENT WITH THE FIELD.
AS THE NUCLEI RELAX BACK INTO
ALIGNMENT, THEY EMIT RADIO WAVES,
WHICH ARE DETECTED BY THE MRI
MACHINE. THE SIGNALS FROM THESE RADIO WAVES ARE
THEN USED TO CREATE IMAGES OF THE INSIDE OF THE
BODY.

ADVANTAGES OF MRI
MRI IS A VERY VERSATILE IMAGING TECHNIQUE THAT
CAN BE USED TO IMAGE A WIDE VARIETY OF
TISSUES IN THE BODY. MRI IS A
NON- INVASIVE AND PAINLESS
PROCEDURE, WHICH MAKES IT A GOOD CHOICE FOR
PATIENTS WHO ARE UNABLE TO UNDERGO OTHER IMAGING
PROCEDURES, SUCH AS CT SCANS OR X- RAYS. MRI
CAN PROVIDE VERY DETAILED IMAGES OF TISSUES IN
THE BODY, WHICH CAN BE USED TO DIAGNOSE A
VARIETY OF MEDICAL CONDITIONS.

DISADVANTAGES OF MRI
MRI MACHINES ARE LARGE AND EXPENSIVE, WHICH
LIMITS THEIR AVAILABILITY. MRI SCANS CAN
BE TIME- CONSUMING, AND THEY MAY NOT
BE SUITABLE FOR PATIENTS WHO ARE
CLAUSTROPHOBIC. MRI SCANS CAN BE
AFFECTED BY METAL OBJECTS IN THE BODY, SO
PATIENTS MUST REMOVE ALL METAL OBJECTS BEFORE
UNDERGOING AN MRI SCAN.

CONCLUSION
MRI IS A POWERFUL IMAGING TECHNIQUE THAT CAN BE
USED TO DIAGNOSE A VARIETY OF MEDICAL
CONDITIONS. MRI IS A NON-
INVASIVE AND PAINLESS PROCEDURE, BUT IT
CAN BE TIME- CONSUMING AND EXPENSIVE. PATIENTS
WHO ARE CONSIDERING AN MRI SCAN SHOULD TALK TO
THEIR DOCTOR TO SEE IF IT IS THE RIGHT IMAGING
PROCEDURE FOR THEM.
