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.

a medicalimaging technique that uses
a strong magnetic field and radio

3. HO W M RI WO RKS
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.

5. ADVANTAGES O F M RI
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.

6. DISADVANTAGES O F M RI
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.

7. 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.
