Describe various neuroimaging techniques that are useful in mental health and their relative advantages and disadvantages. Sample paper:

 There are a variety of neuroimaging techniques that can be useful in the mental health arena. 

The three major types include positron emission tomography (PET), computed tomography (CT), and magnetic resonance imaging (MRI). 

Modern imaging techniques played a primary role in the acceptance of psychology by scientists as psychologists were unable to accept or deny theories since etiologies were based on speculations. 

Neuroimaging is prevalently utilized to rule out any underlying organic brain disorders in the mental health field.
