MRI(magnetic resonance imaging): - It is a medical imaging technique used in reaiology to visualize detailed internal structure. - MRI uses a powerful magnetic field to align the magnetization of some atoms in body, and radio frequency fields to systemically alter the alignment of this magnetization. - Strong magnetic field gradients cause nuclei at different locations to rotate at different speeds. 3-D spatial information can be obtained by providing gradients in each direction. (can identify soft tissue and each part of body which could not be identified by CT imaging)

fMRI (functional MRI) : upgraded version of MRI which can picture the images of actual functional parts of our body. (psychologists usually take fMRI photos of participants' brain)

- can identify which part of brain is in charge of which part of central nervous system.

PET:can differentiate the malignant and benign tumors or cancers. use absorption and activity of glucose to identify photos of CT/MRI
