Areas of the brain which were injured during a stroke will show up "______" on an ADC (apparent diffusion co-efficient) map compared to healthy tissue. Diffusion. This is thermally induced motion of water molecules in tissues. High. A low ADC corresponds to ________ signal intensity on DWI. Low.

A brain MRI (magnetic resonance imaging) scan, also called a head MRI, is a painless procedure that produces very clear images of the structures inside of your head — mainly, your brain. MRI uses a large magnet, radio waves and a computer to produce these detailed images. It doesn’t use radiation. Currently, MRI is the most sensitive imaging test o...
Some brain MRI exams use an injection of contrast material. The contrast agent is often gadolinium, which is a rare earth metal. When this substance is present in your body, it alters the magnetic properties of nearby water molecules, which enhances the quality of the images. This improves the sensitivity and specificity of the diagnostic images. C...
A head MRI and a brain MRI are the same procedure. They both provide images of the inside of your head. While healthcare providers most often use head and brain MRIs to assess your brain, these imaging procedures provide images of other structures in your head, too, such as facial bones, blood vessels and nerves.
A brain or head MRI shows the structures inside of your head, including: 1. Your brain. 2. Blood vessels that connect to your brain. 3. Your skull and facial bones. 4. Structures in your inner ear. 5. Your eyes and their supporting tissues, such as your optic nerves. 6. Other nerves (large nerves in your head, called cranial nerves). 7. Surrounding...
Neurologistsand other healthcare providers order brain MRIs for several different reasons, including helping diagnose new neurological conditions based on certain symptoms or to monitor existing conditions. Some of the conditions a brain MRI can help diagnose or monitor include: 1. A blood clot in your brain. 2. Brain aneurysm. 3. Brain hemorrhage....
A radiologistor a radiology technologist will perform your brain (head) MRI. A radiologist is a medical doctor who performs and interprets imaging tests to diagnose conditions. A radiology technologist is a healthcare provider who’s specially trained and certified to perform an MRI scan.
A brain MRI, also called a head MRI, uses a powerful magnetic field, radio waves and a computer to produce pictures of the brain. The pictures produced are clearer and more detailed than other imaging methods. Magnetic resonance imaging (MRI) does not use ionizing radiation and may require an injection of a contrast material called gadolinium.
Nov 3, 2023 · Normal brain MRI. A brain MRI is one of the most commonly performed techniques of medical imaging. It enables clinicians to focus on various parts of the brain and examine their anatomy and pathology, using different MRI sequences, such as T1w, T2w, or FLAIR. MRI is used to analyze the anatomy of the brain and to identify some pathological ...

Apr 15, 2020 · Learn why each image type is used – this will enable you to know what you are looking for (e.g. for MR brain it’s useful to look at T2, then FLAIR, then DWI/ADC, as this will help distinguish between most differentials). Compare against other imaging modalities. Compare the MRI images to other imaging modalities (e.g. ultrasound, CT, plain ...
