What does sagittal mean in MRI?
A sagittal plane, (also known as median plane) is an y-z plane, perpendicular to the ground, which separates left from right.
What is T1 in brain MRI?
T1 (longitudinal relaxation time) is the time constant which determines the rate at which excited protons return to equilibrium. It is a measure of the time taken for spinning protons to realign with the external magnetic field.
What is normal brain MRI?
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.
What is a sagittal view of the brain?
The sagittal plane divides the right and left side of the brain into parts. The midsagittal plane would divide the right and left sides of the brain into two equal parts, like cutting down the middle of a baked potato before you put on the toppings.
What does sagittal image mean?
The term sagittal is derived from the Latin word sagitta, meaning “arrow”. An image of an arrow piercing a body and passing from front (anterior) to back (posterior) on a parabolic trajectory would be one way to demonstrate the derivation of the term.
How do I read my brain MRI results?
MRI interpretation Systematic approach
- Start by checking the patient and image details.
- Look at all the available image planes.
- Compare the fat-sensitive with the water-sensitive images looking for abnormal signal.
- Correlate the MRI appearances with available previous imaging.
- Relate your findings to the clinical question.
What does T1 and T2 mean on MRI?
T1 images – 1 tissue type is bright – FAT. T2 images – 2 tissue types are bright – FAT and WATER.
What is an abnormal brain MRI?
In the simplest terms, an abnormal brain MRI means that the scan does not show a healthy brain. The scanned image may show structural damages that may indicate injury but also lesions, inflammation, swelling, and bleeding.
What does sagittal view mean?
The sagittal or lateral plane dives the body into left and right halves and is an x-z plane. Technically, the sagittal or median plane goes right through the middle between the body’s left and right halves.
What does sagittal mean in medical terms?
Sagittal Plane (Lateral Plane) – A vertical plane running from front to back; divides the body or any of its parts into right and left sides.
