Basics
MRI stands for this.
what is MAGNETIC Resonance Imaging?
This imaging technology, first developed in the 1970s, revolutionized non-invasive visualization of soft tissues.
What is an MRI?
This type of particle's alignment in a magnetic field is the foundation of MRI imaging.
What are hydrogen protons?
The type of electromagnetic wave that MRI's do NOT use.
X-rays so NO IONIZING RADIATION!!
This type of MRI machine is more comfortable for patients with claustrophobia because it has no tunnel.
What is an open MRI?
The type of field MRI's use
What is magnetic ?
The two names behind MRI and MRI machines
What is Paul Lauterbur & Peter Mansfield?
This principle explains how an oscillating magnetic field causes nuclei to absorb and re-emit energy.
What is resonance (or magnetic resonance)?
The MRI machine detects signals from protons after they do this, once the radio wave pulse is turned off.
What is metal?
This special type of MRI looks at how the brain is working by measuring changes in blood flow.
What is functional MRI (fMRI)?
Types of tissues you can see from an MRI (give examples for bonus points)
what are soft tissues? Examples include : bones, tendons, & muscles
Time and place magnets were found
What is Magnesia before 2500 BC?
The type of pulse the magnetic field uses to align the protons within the body
What is radio frequency?
MRI scans can be uncomfortable for some people due to this condition that makes it hard to stay inside the tube.
What is claustrophobia?
This technology uses MRI to create 3D images of blood vessels without using X-rays.
What is Magnetic Resonance Angiography (MRA)?
This unit of magnetic field strength is commonly used in MRI machines.
What is the Tesla?
In 1971, Paul Lauterbur produced the first MRI image of this object.
What are two test tubes?
The type of magnets MRI machines use
What are permanent & electro magnets?
This type of reaction is rare but possible when a contrast agent like gadolinium is injected.
What is an allergic reaction?
The price range for an MRI
What is $800 to $5,000?
This bodily molecule, abundant in tissues, makes MRI especially useful for imaging soft tissues.
What is water (or hydrogen in water)?
This U.S. physician and inventor filed early patents for using NMR to detect cancer, sparking controversy over credit for MRI’s invention.
Who is Raymond Damadian?
The substance MRI coils are cooled with to create a superconductor
What is liquid nitrogen? (Superconductor is a material that loses all electrical resistance)
Definition of metal interference
When strong magnets can move or heat metal objects in the body (e.g., pacemakers, implants).
The six common types of MRI's. (hint : 2 are mentioned in this section)
What are functional MRI, Magnetic Resonance Angiography, Cardiac MRI, Diffusion MRI, Musculoskeletal MRI, & Abdominal/Pelvic MRI?
