What type of spinning does MRI rely on - CORRECT ANSWER-
Individual spins of protons and neutrons within the nucleus
how do subatomic particles spin - CORRECT ANSWER-they
automatically spin in opposite directions but at the same rate as
their partners. in nuclei that have an even mass number, ex
have the same number of protons and neutrons. half spin in
direction and half the other. the nucleus itself has no net spin.
Angular momentum - CORRECT ANSWER-the spin of MR active
nuclei, which depends on the balance between the number of
protons and neutrons in the nucleus
What are MRI active nuclei? - CORRECT ANSWER-Nuclei with odd
mass numbers where the number of neutrons is slightly more
or less than the number of protons, spin directions are not
equal and opposite so the nucleus it's self has a net spin or
angular momentum
MRI active nuclei - CORRECT ANSWER-Have a tendency to align
their axis of rotation to an applied magnetic field, occurs
,because they have angular momentum or spin, as they contain
positively charged protons, they possess electrical charge
Law of electromagnetic induction, Faraday 1833 - CORRECT
ANSWER-Refers to three individual forces: motion, magnetism
and charge; if two are present then the third is automatically
induced.
Magnetic moment - CORRECT ANSWER-denotes the direction of the
north/south axis of the magnet and the amplitude of the
magnetic field
MRI active nuclei that have a net charge and are
spinning/motion they - CORRECT ANSWER-automatically acquire a
magnetic moment and can align with an external magnetic field
Important MR active nuclei - CORRECT ANSWER-Hydrogen, carbon,
nitrogen, oxygen, fluorine, sodium, phosphorus
what allows the the nucleus to be MR active - CORRECT ANSWER-
although neutrons have no net charge, their subatomic particles
are not evenly arranged over the surface of the neutron and this
imbalance enables the nucleus in which the neutron is situated
to be MR active as long as the mass number is odd
How is alignment measured - CORRECT ANSWER-as the total sum of
the nuclear magnetic moments and is expressed as a vector
quantity.
, the strength of the total magnetic moment is specific to - CORRECT
ANSWER-every nucleus and determines the sensitivity to magnetic
resonance
Protium - CORRECT ANSWER-Isotope of the hydrogen nucleus that is
the MRI active nucleus used in clinical MRI, contains a single
proton, has an atomic and mass number of 1
Why is protium used - CORRECT ANSWER-Because hydrogen is so
abundant in the body and because it's solitary proton gives it a
relatively large magnetic moment. These characteristics enable
utilization of the maximum amount of available magnetization
in the body
Law of electromagnetism - CORRECT ANSWER-States that a magnetic
field is created when a charged particle moves
How does the hydrogen nuclei act as a small magnet - CORRECT
ANSWER-The hydrogen nucleus contains one positively charged
proton that spins or moves, therefore the hydrogen nuclei has a
magnetic field induced around it
What does the magnet of each hydrogen nucleus contain -
CORRECT ANSWER-A north and south pole of equal strength
What is used in the classical theory of the principles of MRI -
CORRECT ANSWER-The north and south axis of each nucleus is
represented by a magnetic moment
