"Magnetic resonance is like an AC alternator or a transformer, the changes in magnetic flux causes a wave of electrons to move through the line."
"Magnetic resonance imaging is like a CT scan, but uses a magnetic field and radiofrequency radiation instead of X-rays. Both CT and MRI scans generally show very detailed images of tumours and their sites of spread."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
