ABOUT
M RI  
Magnetic resoSnanCce AimaNging (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 M RI
WMROI WORKSK BY S 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, WHICHCAUSES 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
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 - INVASIV E       AND       
PA INLE SS  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
M RI
MRI MACHINES ARE LARGE AND EXPENSIVE,   
WHICH LIMITS THEIR AVAILABILITY.
MRI     SCANS     CA N     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.
CONCLUSIO
N 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.
