← ScienceWhich outcome occurs from resonant absorption in MRI?
A)Increased signal tissue contrast✓
B)Decreased magnetic field strength
C)Reduced radio-frequency penetration
D)Augmented static gradients instability
💡 Explanation
When radiofrequency matches the Larmor frequency, resonant absorption occurs; therefore, energy is directly deposited into tissue which increases signal because it allows enhanced differentiation between tissues, rather than affecting the radiofrequency penetration.
