A+ (Just Released)
Bloch showed that: ✔Correct Answer-Atomic protons act like tiny magnets
The energy used to form MR images is __________ the patient's tissues. ✔Correct Answer-Emitted
from
An NMR Spectrometer: ✔Correct Answer-Produces a graph, called a spectrum, of the amount of
each element in an unknown sample
_____________ showed that there are different MRI characteristics between normal and malignant
tissues ✔Correct Answer-Damadian
The first MR image was made during the: ✔Correct Answer-1970s
Which of the following men was awarded the 2003 Nobel Prize for Physiology or Medicine for his
contributions to MRI? ✔Correct Answer-Paul Lauterbur and Peter Mansfield
Which of the following is a characteristic of a mobile MRI system? ✔Correct Answer-Allow several
operators to share one MR system
Which of the following is a characteristic of MRI? ✔Correct Answer-No known long-term harmful
biological effects, Useful in patients requiring repetitive or multiple exams, No know short-term
harmful biological effects
Which of the following is a characteristic of ionizing radiation? ✔Correct Answer-Long-term
exposure has been linked to the development of malignancies, Sufficient energy to cause ionization
of living tissues
Which of the following is a characteristic of plain film x-ray images but NOT of MR images?
✔Correct Answer-The transmitted energy is measured after it passes through the patient, The image
is not a cross-section of the anatomy, A projection "shadow" image is produced
An image acquired perpendicular to the axis running from anterior to posterior in the patient is
called: ✔Correct Answer-coronal
Which of the following is an advantage of MRI but NOT of CT? ✔Correct Answer-The ability to
differentiate soft tissues of the body, No ionizing radiation is used
Which of the following is a characteristic of digital images? ✔Correct Answer-Easily stored on a
computer, Can be electronically transported to remote viewing sites
Arrange plain film x-ray imaging, CT imaging, and MR imaging in order from best to worst in their
overall ability to differentiate the tissues in the body without administering any constrast-enhancing
agent: ✔Correct Answer-MRI is better than CT is better than x-ray
