A 32-year-old male asked:

is one brain mri the same as the next, or does the machine get calibrated differently depending on the symptoms the patient is experiencing?

Calibrated: The brain MRI can be performed with or without contrast agents depending on the suspected cause of the symptoms.

Different: The MRI is callibrated differently from one test to another. This is called a T1 or T2 gradient . It is how fast the hydrogen atoms are moved by the magnet which is how the MRI works. Some scans are used with special dies too.
