Magnetic Resonance Imaging machines have had a huge impact on the way doctors study internal organs and tissues. As a non-invasive method, it produces detailed images of the soft tissues as part of MRI results. To produce the detailed images, MRI uses a magnetic field, a computer and radio waves.
As you already know, our bodies are largely composed of water. The hydrogen atoms in water are magnetic. When exposed to the MRI magnetic field, they align with the field.
The radio waves disrupt the atoms polarity and a sensor measures the time taken for the atoms to realign.
What Does MRI Test For?
With an MRI, doctors are able to examine the tissues and internal organs with high details. As a painless method, it reveals injuries and detects infections. For starters, it identifies the presence of cysts, and other anomalies.
When it comes to breast cancer, it helps in screening women who have a high risk of breast cancer. This enables the patient to take steps early. For the back and knee, it shows any abnormalities or injuries of the joints.
Doctors can also use the machine to find out if you have certain types of cardiovascular problems. For instance, they can look for blocked vessels and problems with the heart structure. If you are undergoing infertility evaluation, an MRI result can reveal any uterine anomalies.
MRI helps with the evaluation of pelvic pain among women. This has been found to be a major cause of endometriosis and fibroids. Last, they can check the health of the following organs:
Thanks to this technology, patients can begin preventative care immediately. This prevents the onset of diseases. Also, it improves their health.
What Can an MRI Show?
The MRI is capable of showing detailed pictures of soft tissues in the body. For instance, it can show detailed images of the brain and other organs. What you need to know is that the machine cannot show certain areas.
For example, it cannot display detailed images of hard bone and air. Since these areas do not give an MRI signal, they appear black on the image. When it comes to blood, soft tissues, bone marrow, and spinal fluid, they may appear black or white.
This depends on the amount of water and fat present in the tissue. It also depends on the settings used during the MRI scan. One of the most popular MRI machines in use today is the Open Upright MRI.
Designed to look like a bagel sliced in half, its perfect for claustrophobic patients. The reason for this is that it has more room inside and is completely open in front. Due to the shape of the MRI, it is unable to capture certain parts of the body.
How to Prepare for an MRI
It is important to let your doctor know if you have any health problems. For instance, liver or kidney disease. Also, you must inform the doctor if you recently had surgery, if you have allergies or are pregnant.
Remember, no metals allowed. That means body piercings, and metal joints among others. On the scheduled day, wear loose clothing with no metal fasteners.
Getting the MRI Results
Before getting your MRI results, the radiologist will review the images. Afterward, he or she will communicate with the doctor. In the doctor’s office, he will discuss the results with you and inform you what steps to take next.
