QuestionAnswer
Name some contraindications of a MRI? (let's say 5 for fun) pacemakers, cerebral aneurysm clips, certain heart valves, IUD's, cochlear implants, neurostimulators, welders, tattoos (eyeliner)
What atom is used for making an MRI? Hydrogen, b/c doesn't have any neutrons so the nucleus is easily magnetized.
For an MRI tissue contrast is weighted based on (FA), (TR), (TE), (TI). What do these abbreviations stand for? FA = Flip angle, TR = Repetition time, TE = Echo time, TI = Inversion time
When is Fat bright, T1 or T2? When is water bright, T1 or T2? In T1 fat is bright and water (CSF) is dark. In T2, H2O is bright, (also he said Nowadays Fat is bright on T2 as well).
***T/F Air, cortical bone, ligaments and tendons have low intensity (dark) signals on ALL sequences? True, what this means is those areas will show up dark on T1, T2, PD (proton density) and STIR sequences
***TR < 1000ms, and T < 30ms, FA = 90 degrees. (is this T1 or T2) T1
****TR > 2000ms, TE > 60ms, and FA = 90 degrees? (is this T1 or T2)? T2
Is the repetition time and echo time larger in T1 or T2 weighted images? T2
True or false? A three week old hemorrhage (subacute hemorrhage) will show up dark on a T1 weighted image. True!
What is it called when the pedicles on C2 are snapped? Hangman's fracture
I would for sure know the numbers for T1 and T2, and what shows up on each. That means don't discard the flashcards until you fear them as if they were giggleman
