Physics
The magnetic field strength (Bo) unit of measure.
What is Tesla?
This scientist invented alternate current and magnetic field rotation in his NY lab, ultimately being the first to measure magnetic field strength.
Who is Nikola Tesla?
DWI is the abbreviation for this MRI sequence.
What is diffusion weighted imaging?
A fluid filled cyst is best visualized with this sequence.
What is T2 weighted?
The three planes of a 3D MRI image.
What are x, y, and z?
"TE" in an MRI sequence
Echo Time or Time to Echo
These collaborators at Columbia University coined the term "nuclear magnetic resonance."
Who are Rabi and Gorter
This short TR and short TE sequence will result in an image with high signal from fat (white) and low signal from water (black).
What is a T1 weighted image?
White matter integrity, or the structure of axons, can be visualized with this sequence.
What is DWI (diffusion weighted) or DTI (diffusion tensor)?
The anterior-most lobe of the brain.
What is the frontal lobe?
These atoms are the primary source of the MRI signal
What are hydrogen atoms?
This physicist from the 1800s conducted the coil experiment to discover electromagnetism could create a direct current.
Who is Michael Faraday?
This sequence appears as the inverse of a T1 weighted image, with fat giving off low signal (black) and fluid giving off high signal (white).
What is a T2 weighted image?
This sequence would be used immediately after an injury to assess swelling or edema.
What is FLAIR?
The name of the view along the X axis.
What is the sagital view?
The degree to which nuclear polarity and rotation
changes give off sine waves.
What is resonance?
These colleagues demonstrated different atomic structures create different signals.
Who are Bloch and Purcell?
This sequence produces a T2 weighted image, but with the signal from fluid attenuated to lower the hyperintense signal so that it appears black.
What is FLAIR?
If you wanted to watch brain activity (blood oxygenation) during a cognitive task, you would use this sequence.
The brain region that Erickson and Miller described as changing in volume in relation to physical activity and photoperiod.
What is the hippocampus?
This mathematical conversion turns sinusoidal waves into frequencies.
What is the Fourier Transform?
In 1954, this scientist published the first paper examining biological tissue using NMR imaging.
Who is Erik Odeblad?
This sequence consists of a tagging pulse along one plane in the neck, followed by a delayed series of volumes across the brain to calculate perfusion.
What is ASL (arterial spin labeling)?
White matter hyperintensities, which are thought to be lesions throughout the white matter, are best visualized using this sequence.
That is FLAIR?
What is the visual cortex? (occipital lobe)
