Breast MRI is a highly accurate diagnostic imaging of breast tissues using strong magnetic fields and radio waves combined with a computerized digital system. It is often recommended when other tests like ultrasounds and mammograms fail to provide a precise diagnosis for tailoring a comprehensive treatment approach.
Learn here about the science behind an MRI and what the procedure involves.
How does an MRI work?
An MRI is a large, tube-like machine that creates a strong magnetic field along with radio waves. This alters the natural alignment of hydrogen atoms in your body. Computers are used to create a 2D image of your body structure and organ, based on the activity of the hydrogen atoms. A magnetic field is created and signals of radio waves are sent from a scanner. These signals are received by a computer that analyzes and converts them into an image of the part of the body being examined. This image appears on a projected monitor screen.
How do you prepare for a breast MRI?
You may prepare yourself in the following ways for a breast MRI:
- Eat a good meal as usual
- You must change into a patient gown and remove all jewelry.
- Inform your doctor about any past allergic reactions to contrast dyes
- If you are extremely claustrophobic take an anti-anxiety medication after consulting your doctor
- Inform your doctor if you:
- Are pregnant
- Are breastfeeding
- Have any pacemaker
- Have any body piercing
- Have any metal plates or pins
- Have any permanent tattoo
- Are not able to lie on your stomach
What happens during a breast MRI?
In general, an MRI follows this process:
- An IV line will be given for injecting the contrast dye
- You will lie on a scan table on your stomach. The table will have special openings for your breasts
- You will be given earplugs to help block out the loud noise from the scanner
- You must stay still while the machine scans your breasts
- A contrast dye may be injected mid-way
- Once the scan is over you will be off the table and the IV line will be removed
Bottom line
Breast MRIs can help detect abnormalities accurately since they offer accurate breast tissue images. If you think you suffer from any breast abnormality seek medical help immediately for further evaluation. Your doctor may recommend diagnostic tests like ultrasounds, mammography, or MRI. An MRI is the most preferred diagnostic aid since it offers superior accuracy in a short span of time.
