Magnetization Is Different for Various Tissues

question 20

Multiple Choice

Magnetization is different for various tissues. With many tissues involved in magnetic resonance imaging, we need to obtain the best possible contrast. Magnetic resonance imaging is, for this reason, done in three modes. Which of the following is NOT one of the modes?

• A)a mode that emphasizes contrast due to proton density
• B)a mode that emphasizes contrast due to photon density
• C)a mode that emphasizes contrast due to relaxation time T1
• D)a mode that emphasizes contrast due to relaxation time T2
