The magnetic resonance imaging is used as a tool of diagnosis to detect the injuries in human body. It is based on the principle that:
Protons in different types of human tissues have specific magnetic field environment
Magnetic field pattern of human body resonates with the externally applied magnetic field
Either $(1)$ or $(2)$
Neither $(1)$ nor $(2)$
The basic principle of MRI is protons in different types of human tissues have specific magnetic field environment.
