Magnetic resonance imaging, known as MRI, of the head, uses a high magnetic field, radio waves, and a computer to produce more detailed images of the brain and other cranial structures than previous imaging modalities. This exam does not employ ionizing radiation and may necessitate the injection of gadolinium contrast material, which is less likely to trigger an allergic reaction than iodinated contrast material.
Inform your doctor about any health issues, recent surgeries, allergies, and the likelihood of pregnancy. Although the magnetic field is not dangerous, it may cause some medical instruments to malfunction. Although most orthopedic implants are safe, you should always inform the technician if you have any gadgets or metal in your body.
The rules for eating and drinking before your exam depending on your doctor’s advice. Take your regular medicines with the permission of the doctor. Wear loose, comfy clothing and leave your jewels at home. If you experience claustrophobia or anxiety, you should immediately consult your doctor.Consult the best diagnostic center to know mri scan cost in Hyderabad to schedule your test.
What Is a Head MRI Scan?
A painless, noninvasive examination that gives detailed images of your brain and brain stem is magnetic resonance imaging (MRI) of the head. The images are created by an MRI machine utilizing a magnetic field and radio waves. This examination is often referred to as a brain MRI or cranial MRI. You will be taken to a hospital or radiology center for a head MRI.
An MRI scan differs from a CT or an X-ray because it does not produce images using radiation. Because an MRI combines pictures to generate a 3-D view of your interior tissues, it is more successful than other scans at detecting abnormalities in microscopic brain regions like the pituitary gland and brain stem.A contrast agent, or dye, may be administered via an intravenous (IV) line to visualize particular structures or abnormalities better.
What Does a Brain MRI Reveal?
Your doctor can view details of blood flow and fluids surrounding the brain in MRI pictures, which can assist in diagnosing abnormalities in the brain about arteries and veins.
An MRI brain scan reveals brain lesions as well. A brain lesion is a dark or light patch on the brain that does not resemble normal brain tissues. Brain lesions can result from multiple sclerosis, an infection, or a tumor.
A brain MRI will generally allow your doctor to check blood flow and tissue health in the brain areas listed below.
- The cerebrum is the front section of the brain responsible for movement, body temperature, touch, vision, hearing, thinking, emotions, and learning.
- The brainstem is located at the center of the brain. This area is responsible for eye and mouth movements, sensory messages, hunger, consciousness, heart function, and involuntary muscular movements.
- The cerebellum is the brain’s backbone that coordinates voluntary muscle movements and aids with posture and balance.

What Happens During A Head MRI?
It is critical to remain still during the exam to capture the most explicit photos. Sedation, either orally or through an IV line, may be required for children with difficulties staying still. Adults who feel claustrophobic may benefit from sedation as well.
You will be positioned on a table,gliding inside the MRI machine. The table moves through a giant magnet in the shape of a tube. A plastic coil may be wrapped around your head. After the table is inserted into the machine, a professional will take a few minutes to photograph your brain. The device will have a microphone that will allow you to communicate with employees.
The exam usually lasts 30 to 60 minutes. You may be given a contrast solution, usually gadolinium, by IV to help the MRI scanner see certain portions of your brain, particularly your blood arteries. During the operation, the MRI scanner will generate loud pounding noises. You may be supplied earplugs to filter out the noises of the MRI scanner, or you may listen to music during the test.
There are no hazards associated with having an MRI. There is minimal possibility that you will be allergic to a contrast solution. However, inform the medical personnel if you have diminished renal function. Using a contrast solution may not be safe if this is the case.
Who Interprets The Results, And How Do I Obtain Them?
The images will be analyzed by a radiologist, a doctor trained to supervise and interpret radiology exams. The radiologist will sign the report and transmit it to your primary care or referring physician, who will discuss the findings with you.
A follow-up exam may be required and your doctor will explain why. For example, a follow-up test may be necessary to analyze further a potential problem with more views or a particular imaging technology. It may also check to see if an issue has changed over time. Follow-up assessments are frequently the best approach to determine whether treatment is effective or whether a condition requires addressing.
