Brain MRI: What It Is, Procedure and Does Your Whole Body Go In For the Scan
In this comprehensive guide, we will talk about brain MRI scans. Furthermore, we will discuss its procedure, benefits, and does your whole body go in for a brain MRI.
In the ever-evolving medical imaging landscape, Magnetic Resonance Imaging (MRI) has emerged as a powerful diagnostic tool. It enables healthcare professionals to delve deep into the human body, including the intricate complexities of the brain.
Understanding the Basics of Brain MRI
What is an MRI?
With the use of strong magnets and radio waves, magnetic resonance imaging creates precise cross-sectional pictures of the internal organs of the human body without using any harmful radiation. Unlike other imaging techniques like X-rays or CT scans, MRI doesn’t use ionizing radiation, making it a safer alternative for both patients and medical personnel.
How Does MRI Work?
At the heart of MRI lies the interaction between the body’s hydrogen atoms and the powerful magnetic field generated by the MRI machine. When exposed to the magnetic field, the hydrogen atoms align themselves in a specific manner.
The subsequent introduction of radiofrequency pulses causes these atoms to resonate, emitting signals that the MRI machine’s detectors capture. A computer then processes these signals to create highly detailed images, showcasing various tissue types and structures within the body.
The Role of Brain MRI
Why is Brain MRI Necessary?
You must wonder why would a neurologist order an MRI of the brain. A wide variety of neurological diseases and illnesses may be accurately diagnosed using brain MRI. From detecting the presence of tumors and lesions to evaluating blood vessel abnormalities and assessing the effects of trauma, Brain MRI provides invaluable insights into the brain’s inner workings.
This non-invasive imaging method enables medical professionals to make precise diagnoses, plan treatments, and track the development of a variety of neurological diseases over time.
Common Uses of Brain MRI
Tumor Detection: Brain MRI is highly sensitive in detecting both benign and malignant brain tumors. Its ability to provide detailed images helps healthcare professionals determine the tumor’s size, location, and characteristics, which are essential for treatment planning.
Stroke Evaluation: Timely intervention depends on a quick and correct assessment of strokes. Brain MRI helps identify the type and location of a stroke, guiding medical teams in choosing the appropriate treatment approach.
Multiple Sclerosis (MS): MRI of the brain is instrumental in diagnosing and monitoring the progression of MS. It helps visualize the presence of lesions in the brain and spinal cord, aiding in early detection and management.
Neurodegenerative Diseases: Brain MRI can be used to diagnose diseases like Alzheimer’s and Parkinson’s. The method makes it possible to see the structural alterations in the brain that are a sign of these illnesses.
The Brain MRI Procedure
Preparing for the MRI
Patients might have to adhere to particular guidelines before having a brain MRI, such as fasting or avoiding certain drugs. Any pacemakers, metal implants, or other medical equipment must be disclosed to the healthcare practitioner since they may affect the results of an MRI.
During the MRI
During the procedure, the patient lies down on a padded table that slides into the MRI machine. To obtain clear and precise pictures during the scan, you must stay motionless. Due to the machine’s small size or the loud noises it makes, some people could feel slight pain. Patients are often provided with earplugs or headphones to mitigate these effects.
Post-MRI Care
Patients can often continue their regular activities right away after the brain MRI. A radiologist then analyzes the image scans carefully and generates a comprehensive report for the healthcare provider.
Does Your Whole Body Go In For a Brain MRI?
You must be wondering does your whole body go in for a brain MRI. In a brain MRI, only the head and upper neck region of the body typically slide into the MRI machine. The rest of the body remains outside the machine. The MRI machine itself is a cylindrical tube with a tunnel-like structure where the patient lies down. The patient’s head is inserted inside the tube throughout the entire procedure, while the body stays outside.
It’s important to note that only the specific area being examined, in this case, the brain and surrounding structures, is captured in the MRI images. The MRI machine is designed to focus on the targeted region to provide detailed and accurate images. This focused approach allows for better visualization and assessment of the brain’s anatomy and any potential abnormalities.
Patients undergoing a brain MRI will need to lie still during the procedure to ensure the clarity of the images. Some individuals might find the confined space of the MRI machine uncomfortable, and healthcare providers from Diagnostic Imaging Network take steps to help patients feel more at ease, such as providing earplugs or using an open MRI machine if available.
What Does Hyper Intensity Mean On The MRI Report?
Hyperintensity refers to an area on the image produced by the MRI scan that appears brighter than the surrounding tissue. This increased brightness is usually observed on T2-weighted or fluid-attenuated inversion recovery (FLAIR) images. However, what does hyperintensity mean on an MRI report? It can indicate various conditions or changes within the body, including:
Fluid Accumulation
Hyperintense areas may indicate the presence of fluid, such as edema (swelling) or accumulation of cerebrospinal fluid. These areas can be indicative of inflammation or other pathological processes.
Ischemia or Infarction
In certain cases, hyperintensity can signal reduced blood flow or lack of blood supply to a particular area, which might be a sign of ischemia or tissue infarction (cell death due to lack of blood flow).
Lesions
Hyperintense regions could represent lesions, which might be caused by a variety of factors, including infection, inflammation, or tumors.
Demyelination
In conditions like multiple sclerosis (MS), hyperintense areas may suggest demyelination, where the protective covering of nerve fibers (myelin) is damaged.
Aging and Normal Changes
As individuals age, hyperintense spots, often referred to as “white matter hyperintensities,” might appear in brain MRI scans. These are associated with normal aging and changes in the brain’s blood vessels.
Other Pathological Changes
Hyperintensities can also be linked to other pathological changes, such as certain neurodegenerative diseases, infections, or vascular abnormalities.
It’s important to note that interpreting hyperintense areas in an MRI report requires expertise and context. A radiologist or medical professional with experience reading MRI scans will analyze the images and provide a comprehensive assessment of any findings.
The appearance of hyperintensity alone may not always signify a particular illness. Rather, it is a potential marker that warrants further investigation and clinical correlation to determine its underlying cause.
How Long Does It Take To Get MRI Results?
What is the turnaround time for MRI results? Usually, a number of variables affect how long it takes to get MRI findings. The following timetable for getting your MRI findings is what you may typically anticipate:
Immediate Preliminary Findings
In some cases, especially in emergency situations, a radiologist may provide immediate preliminary findings to the healthcare provider shortly after the MRI scan. This initial assessment can help guide immediate medical decisions.
Official Report
A radiologist typically generates a comprehensive radiology report, which includes a thorough analysis of the MRI images. This report is then sent to the healthcare provider. The turnaround time for this report can vary. However, it is often available within a few days to a week after the scan from Edison Diagnostic Imaging Services.
Follow-Up Appointment
Upon release of the radiological report, your healthcare professional will discuss the findings with you during a subsequent session. They will explain the findings, discuss any relevant diagnoses, and recommend appropriate next steps or treatments based on the MRI results.
It’s important to note that the exact timeline for receiving MRI results can vary. It’s based on factors like the type of facility, the availability of radiologists, the urgency of the case, and the overall workload of the facility.
If you want to receive your MRI results early, discussing them with your healthcare provider or imaging center is best.
