What does FLAIR mean in CLINICAL MEDICINE
FLAIR stands for Fluid Attenuated Inversion Recovery. It is a magnetic resonance imaging (MRI) technique that uses a specific sequence of radiofrequency pulses to suppress the signal from cerebrospinal fluid (CSF). This allows for better visualization of the brain and spinal cord, as well as other structures that are surrounded by CSF.
FLAIR meaning in Clinical Medicine in Medical
FLAIR mostly used in an acronym Clinical Medicine in Category Medical that means Fluid attenuation inversion recovery

FLAIR Meaning in MEDICAL
In medical imaging, FLAIR is used to:
- Detect abnormalities in the brain and spinal cord, such as tumors, strokes, and multiple sclerosis
- Evaluate the extent of inflammation or edema in the brain or spinal cord
- Visualize the flow of CSF
- Help diagnose and monitor conditions that affect the brain and spinal cord, such as Alzheimer's disease, Parkinson's disease, and epilepsy
FLAIR Full Form
- Fluid
- Attenuated
- Inversion
- Recovery
How FLAIR Works
FLAIR works by using a series of radiofrequency pulses to invert the magnetization of the protons in the CSF. This means that the protons in the CSF will be aligned in the opposite direction of the protons in the other tissues. When the MRI scanner acquires the signal, the protons in the CSF will produce a negative signal, while the protons in the other tissues will produce a positive signal. This results in the suppression of the CSF signal, making it possible to visualize the brain and spinal cord more clearly.
Essential Questions and Answers on Fluid attenuation inversion recovery in "MEDICAL»CLINICAL"
What is Fluid Attenuated Inversion Recovery (FLAIR)?
FLAIR is a magnetic resonance imaging (MRI) technique that suppresses the signal from fluids, such as cerebrospinal fluid (CSF) and blood, while enhancing the visibility of tissues. It is commonly used to evaluate the brain and spinal cord.
How does FLAIR work?
FLAIR uses a combination of inversion recovery and fluid suppression techniques. First, an inversion pulse is applied to invert the magnetization of all protons in the tissue. Then, a series of radiofrequency pulses is applied to selectively suppress the signal from fluids, leaving the signal from tissues intact.
What are the advantages of FLAIR MRI?
FLAIR MRI offers several advantages over conventional MRI techniques:
- Improved contrast between tissues and fluids: FLAIR suppresses the signal from fluids, making it easier to visualize tissues that are normally obscured by CSF or blood.
- Reduced artifacts: FLAIR reduces artifacts caused by fluid motion, such as those seen with conventional MRI techniques.
- Increased sensitivity to subtle lesions: FLAIR can detect small lesions that may be difficult to see with other MRI techniques.
What are the limitations of FLAIR MRI?
FLAIR MRI has some limitations:
- Longer scan times: FLAIR MRI scans take longer than conventional MRI scans.
- Reduced spatial resolution: FLAIR MRI has a lower spatial resolution than conventional MRI scans.
- Limited sensitivity to certain tissues: FLAIR MRI is not as sensitive to certain tissues, such as bone and air.
What are the clinical applications of FLAIR MRI?
FLAIR MRI is used in a variety of clinical applications, including:
- Brain imaging: FLAIR MRI is used to evaluate the brain for conditions such as stroke, multiple sclerosis, and Alzheimer's disease.
- Spinal cord imaging: FLAIR MRI is used to evaluate the spinal cord for conditions such as spinal cord injury, multiple sclerosis, and tumors.
- Head and neck imaging: FLAIR MRI is used to evaluate the head and neck for conditions such as sinusitis, tumors, and vascular malformations.
Final Words: FLAIR is a valuable MRI technique that provides detailed images of the brain and spinal cord. It is used to diagnose and monitor a wide range of conditions that affect the central nervous system. FLAIR is a safe and non-invasive procedure that can provide valuable information for healthcare professionals.
