A brain scan is an imaging test that allows doctors to see the structure and activity of your brain. It can help them diagnose and treat conditions like epilepsy, traumatic brain injury, stroke and dementia. The primary tool used for this is called a functional magnetic resonance imaging (fMRI).

Using fMRI technology, practitioners can identify active areas of the brain by measuring changes in its blood flow as it responds to specific tasks or stimuli. This helps them compare normal activities in the brain to abnormal ones that may be caused by neurological disorders or illnesses.

Brain scans also provide a detailed overview of your brain’s structure, which is important for understanding why certain conditions occur. Structural MRI (sMRI) uses magnetic fields and radio waves to create detailed images of your skull and soft tissues within it. This lets healthcare professionals spot changes in the texture or shape of any part of your brain, including your gray matter and white matter areas that are responsible for thought processes and coordination movements.

Brain scans are also used to monitor drug therapy or any other treatments you may be undergoing as part of a medical condition. By regularly checking on how your brain functions through imaging tests, practitioners can make more informed decisions about managing your care plan more effectively.

What is a Brain Scan?

A brain scan, also known as a neuroimaging study, is a non-invasive procedure that uses specialized technology to get images of the structure and function of the brain. Brain scans can help diagnose and monitor a range of neurological conditions, including dementia and epilepsy. They can also be used to track the progression of diseases and to assess the effects of treatments.

Let’s take a closer look at how the technology works and what the results can tell us:

Types of Brain Scans

Brain scans are a valuable method medical professionals can use to diagnose medical conditions. There are two major types of brain scans: structural MRI scans and functional MRI scans.

Structural MRI Scans: Structural MRI scans provide images of the entire brain in cross section. They are used to identify disease, trauma, or congenital deformity that affects anatomical structure. This can reveal tumors that were not previously seen on other forms of imaging, as well as pinpoint particular issues such as strokes or aneurysms.

Functional MRI Scans: Functional MRI (fMRI) scans measure the active functions of the brain, as opposed to simply mapping its physical anatomy. This type of scan provides an insight into areas in our brains that control certain mental processes—such as planning and problem-solving—which allow us to form thoughts according to expressions of emotions or imagination. On fMRI machines, technicians use sophisticated software to study a patient’s reactions when presented with stimuli—such as a picture or thought experiment—in order to measure changes in oxygen levels throughout the brain. These changes indicate which areas are being used more heavily during mental exercises, leading physicians to possible diagnoses regarding psychological disorders or physical injuries like Alzheimer’s or Parkinson’s Disease.

Benefits of Brain Scans

Brain scans, also known as imaging studies, can provide important information about the structure and function of the brain. With a brain scan, doctors are able to evaluate how a person’s brain is working and diagnose certain diseases or conditions that may be causing headaches, confusion, seizures and other neurological symptoms.

There are many benefits to having a brain scan. These include:

  • Identifying and understanding physical abnormalities in the brain like tumors, bleeding or inflammation.
  • Detecting areas of decreased blood flow or oxygen in the brain. This can help to diagnose diseases such as stroke and Alzheimer’s.
  • Helping to determine if there has been any physical damage from an accident or injury.
  • Assessing changes in brain structure due to illnesses like dementia or depression.
  • Analyzing changes over time for conditions like multiple sclerosis (MS) and epilepsy that can cause varying levels of impairment throughout life.

Additionally, brain scans are often used in research studies to gain insight into different psychiatric disorders such as bipolar disorder, schizophrenia, anxiety disorders and post-traumatic stress disorder (PTSD). The insights gained from these studies can be used to develop more effective treatments for these conditions. Brain scans may also show differences between people who have certain mental illnesses and those who do not have them.

What Can a Brain Scan Tell You?

Brain scans are an incredibly powerful tool for diagnosing and understanding how different parts of the brain are activated. By measuring different components of the brain such as electrical activity, oxygen levels, and blood flow, medical professionals and scientists can learn more about how the brain functions and how it is affected by diseases and disorders.

In this article, we’ll take a look at what a brain scan can tell you about your current state of health.

Brain Structure

Brain scans can be used to detect changes in the structure of the brain. Structural MRI, a type of MRI scan, uses powerful magnets and radio waves to produce detailed images of various parts of the brain. It is used to look for any abnormalities that might explain a person’s symptoms or suggest an underlying medical condition. For example, structural scans can be used to track the progression of brain tumors and other cancerous growths, as well as neurological diseases such as dementia.

When doing a structural scan, healthcare professionals measure heights, widths, and depths between different parts of the brain in order to accurately compare these measurements against predetermined normal values. These values are based on large-scale databases which allow for comparison among individuals and for changes over time within the same individual. With this data healthcare professionals are able to detect any areas where there may be too much or too little activity or damage in certain areas compared to normal functional processing.

Structural scans also provide more information than just numbers. Different colors represent different kinds of tissues in our brains, helping identify areas that may need further evaluation or follow-up scans so that any possible issues can be pinpointed earlier rather than later. Brain scan engineering technology has enabled us to peer into our brains more than ever before and understand our anatomy at unprecedented levels Never before seen imaging techniques have made it possible for medical teams across all disciplines spot abnormalities earlier when treatments are more effective for better patient care and overall outcomes with less costly measures over time.

Brain Function

Brain scans, also known as neuroimaging, are tests that study the structures or functions of the brain through the use of a variety of imaging technologies. The most common types of brain scans detect abnormalities in physical anatomy such as tumors, trauma or acquired developmental delays.

In addition to identifying physical problems, brain scans can also be used to evaluate neurochemical processes and underlying neural networks that are associated with specific behaviors. By looking at how the different parts of the brain correspond to behavior, scientists can more easily understand how they work and how they might be changed through medical treatment or therapy.

Brain scans can be used to test for conditions such as depression and ADHD based on functional changes in certain regions of the cerebrum or activity in certain neuronal pathways. By taking an image from different angles, it is possible to piece together a detailed three-dimensional picture of what is going on within each part of an organ such as the brain and identify localized changes in structure or function. Through studies on individuals who have had strokes or Alzheimer’s disease, doctors and researchers also use brain scans as a way to measure patterns in dysfunction in order to help diagnose these conditions in other patients.

Brain Activity

Brain scans can provide invaluable insight into how our brains work. They are used to examine a person’s present and past neurological (brain-related) function. During a brain scan, hospitals or clinics use technologies such as MRI, CT scans, EEGs and PET scans to create detailed images of the brain. These images show general brain activity, including which areas are active or inactive in response to certain stimuli.

Brain scans help doctors diagnose a variety of conditions, such as tumors or strokes. They can also be useful for monitoring the progress of treatment and health management plans. Brain scan results can reveal conditions that would not be detected by traditional methods such as physical examinations or blood tests. For example, a head injury leading to memory loss might not appear on an x-ray but would on an MRI or CT scan.

Beyond diagnostic applications, brain scans also play an important role in research studies involving the mind/body connection or psychological issues like depression and anxiety disorders. Functional Magnetic Resonance Imaging (fMRI) shows how well different parts of the brain communicate during various tasks and activities – essentially mapping out our cognitive processes at work in real time! Brain scanning technology is advancing rapidly – allowing us to understand potential new treatments for previously mysterious conditions like Alzheimer’s disease and addiction.

Brain Injury or Disease

Brain scans, such as MRI and CT scans, can provide doctors with valuable information about the structure and function of a person’s brain. They can be used to diagnose or monitor brain injury or disease, look for tumors or other anomalies, detect signs of stroke and other vascular issues, identify areas of abnormality due to injury or infection, study the effects of drugs on the brain and more. Brain scans are a crucial tool in diagnosing brain conditions such as Alzheimer’s Disease, multiple sclerosis, traumatic head injuries and other neurological disorders.

MRI (magnetic resonance imaging) imaging creates detailed pictures that show the physical structure of the brain including soft tissue and nerve pathways. The scan uses magnetic fields, radio waves and fluid contrast to create images that are helpful in diagnosing a variety of neurological conditions including: stroke, traumatic head injury (TBI), tumors, infections such as meningitis or encephalitis, dementia such as Alzheimer’s Disease, hydrocephalus (an excess accumulation of fluid in or around the brain) and epilepsy.

CT (computed tomography) is similar to an MRI but utilizes X-rays to generate views from different angles. It is able to provide detailed images quickly to help identify problems caused by trauma such as blood clots or bleeding within the skull. It can also be used to identify infection by finding areas that appear swollen compared with surrounding tissues. In some cases it may offer better results when examining structures where tissue appears intact but has been damaged in some way – like after a stroke.

Brain scans are invaluable tools in identifying abnormalities caused by injury or disease and allow doctors to develop effective treatments plans accordingly.


Brain scans are useful tools in the diagnosis and treatment of various conditions. By using brain scanning technology, medical professionals can detect abnormalities in a person’s brain and determine the best course of action. Through brain scans, doctors can observe how different brain regions respond to stimuli, allowing them to understand how a patient’s disease or injury is affecting their daily life.

The information obtained from a brain scan can help doctors design targeted treatments for an individual’s condition, so that they can address the problem in an effective manner. Brain scans should not be used as an isolated diagnosis tool, however; medical practitioners should always take into account a person’s history and other diagnostic tests before reaching a clinical decision. Even when used in conjunction with other diagnostics, it is essential that doctors explain the meaning of results from brain scans to ensure that patients understand what is happening inside their heads.
